step S102: and acquiring house information of the target house.
The target house may be a house in which the position of the internal light source is required to be determined when the decoration design is performed. The house information is information that needs to be extracted from the target house when the light source position determination is performed, so as to determine the light source position based on the extracted house information. In one embodiment, house information may be obtained by identifying a house pattern of a target house, to obtain a complete house pattern scheme, and according to the obtained house pattern scheme data, the obtained house information includes: wall information, door and window information, outline information of a house pattern and the like, and obtaining indoor layout information in a house according to house information of the target house, wherein the indoor layout information comprises the following components: furniture position information, furniture height information, furniture shape and size information, and the like.
Step S104: determining a target house type diagram of a target house based on house information; the target floor plan includes one or more of furniture position information, furniture height information, and furniture shape and size information.

And drawing a target house pattern diagram of the target house based on the wall information, the door and window information, the outline information of the house pattern diagram and the indoor layout information in the house information.
Step S106: and determining the light source position of the target house based on the deep learning algorithm and the target house pattern.
The target house type diagram comprises wall information, door and window information, outline information of the house type diagram, furniture position information, furniture height information and furniture shape and size information of the target house, the light source position of the target house is determined based on a deep learning algorithm and the target house type diagram, influences of indoor furniture size and furniture placement position of a furniture altimeter on the light source position are fully considered according to actual scenes of the target house, a light source position result obtained based on the deep learning algorithm is more fit with the actual situation, and the rationality of light source position determination is improved.
According to the method for determining the light source position, provided by the embodiment of the invention, on the basis of fully considering the light source position influence factors (furniture position information, furniture height information and furniture shape and size information), the light source position in the target house can be rapidly determined based on the deep learning algorithm and the target house type diagram of the target house, so that the calculation efficiency of determining the light source position is improved.
The existing light source position determining technology does not consider furniture height information in the target house, so that the light effect of the determined light source position is poor, and the light source position determining method provided by the embodiment of the invention also considers furniture height in the target house, optimizes the light source position determining method and improves the accuracy of determining the light source position.
In order to improve the rationality of light source position determination, the embodiment provides a specific implementation manner of determining the house pattern diagram of the target house based on house information, wherein the house information comprises house outline and indoor layout information, and the specific implementation manner can be implemented with reference to the following steps (1) to (3):
step (1): and determining furniture arrangement information of the target house based on the house outline and the indoor layout information, and determining furniture shape and size and furniture position information of the target house according to the furniture arrangement information of the target house.
The furniture arrangement information can also be obtained based on a house pattern of the target house, the furniture arrangement information comprises the arrangement position of each piece of furniture in the house, a top view of the piece of furniture and size information of the piece of furniture, the arrangement position can be the relative position relation between the piece of furniture in the house and the wall body outline, and the shape, size and position information of the piece of furniture in the target house can be determined based on the house outline and the indoor layout information in the house information.
Step (2): and determining a furniture graph according to the furniture shape and the size of the target house, and determining the color depth of the furniture graph according to the furniture height of the target house.
In one embodiment, the furniture image can also be determined from the top view of the piece of furniture and from the dimensional information of the piece of furniture. The shape of the furniture graph is determined according to the shape of the top view of the furniture, for example, the top view of the wardrobe and the bed is rectangular, the wardrobe and the bed are represented by rectangles with different sizes, and the size of the furniture can be reduced by a preset proportion according to the actual size of the furniture, so that the size of the furniture graph is obtained. In order to convert three-dimensional information (e.g., the height of furniture) in a target house into two-dimensional information, the color depth of a furniture pattern may be determined according to the height of furniture in the target house, so that the furniture height information is represented by furniture patterns of different shades, for example, a relationship table of the color depth of the furniture pattern and the height of furniture may be established, and the height of furniture may be determined according to the relationship table and the color of the furniture pattern.
In another embodiment, according to the top view of all pieces of furniture and according to the position information of the pieces of furniture, the maximized rectangle is drawn to just surround all parts of the furniture, so that each piece of furniture can be represented by a rectangular block, and as the specific furniture outline and furniture texture have small influence on the calculation of the light source position, pieces of furniture in the target house can be determined as rectangular blocks with different sizes, the aspect ratio of the rectangular blocks can be determined according to the aspect ratio of the actual size of the furniture, and the aspect ratio of the rectangular blocks of different pieces of furniture is different.
Step (3): and determining a target house type graph of the target house based on the furniture position information, the furniture graph and the color depth of the furniture graph.
In order to make the calculated light source position more accurate, the target house type graph can contain more influencing factors influencing the light source position, for example, furniture in the target house has a great influence on lamplight, including the size, placement and height of the furniture, and the target house type graph of the target house is determined according to the furniture position information, the furniture graph and the color depth of the furniture graph, so that the house type graph includes the furniture position information, the furniture height information and the furniture shape and size information.
In order to improve the accuracy of light source position determination, the embodiment provides a specific implementation manner of determining the light source position in the target house type diagram based on a deep learning algorithm and the target house type diagram: inputting the target house type graph into a pre-trained DCGAN (Deep Convolution Generative Adversarial Networks) network model, generating an countermeasure network by deep convolution, and determining the light source position of the target house based on the DCGAN network model; the DCGAN network model is obtained based on a known house type graph and light source position training of the known house type graph. Firstly, training the DCGAN network model by using a known house type graph and the light source position of the known house type graph, wherein the known house type graph comprises wall information, door and window information, outline information of the house type graph, furniture position information, furniture height information and furniture shape and size information in the known house type, inputting the light source positions of the known house type graph and the known house type graph into the DCGAN network model, and training the DCGAN network model to enable the DCGAN network model to learn the mapping relation between the information of the known house type graph (comprising the wall information, the door and window information, the outline information of the house type graph, the furniture position information, the furniture height information and the furniture shape and size information) and the light source position of the known house type graph. The target house type diagram is input into a trained DCGAN network model, and the trained DCGAN network model can determine the optimal light source position in the target house according to wall information, door and window information, outline information of the house type diagram, furniture position information, furniture height information and furniture shape and size information in the target house type diagram. The DCGAN network model obtains the light source position of the target house type graph in a backtracking mode based on the existing high-quality rendering scheme effect graph. The light source position may be output as the vertex coordinate position of the pixel region, or may be output by drawing the pixel region of the light source position on the target floor plan.
The DCGAN network model is a combination of CNN (Convolutional Neural Networks, convolutional neural network) and GAN (Generative Adversarial Networks, generating type countermeasure network), which introduces the convolutional network into the generating type model to perform unsupervised training, and utilizes the strong feature extraction capability of the convolutional network to improve the learning effect of the generating network. In one embodiment, the DCGAN network model in the present application adopts a GAN in a base version, where two opposite networks G and D are used in the GAN, G is a generating network, D is a discriminating network, the purpose of G is to generate an image through network parameters, D is to determine true and false of the image, the two networks are mutually opposed, the more true the image generated by the G is, the higher the probability of judging errors by the D is, and because a trained group is provided, the capability of the D can be continuously improved, and in turn, the capability of the G to generate a higher quality image can be continuously promoted, so that in the continuous mutual opposed promotion, the G can completely generate data which is almost close to a real image, and the main purpose is to better extract the characteristics of a target household pattern graph by introducing a convolutional neural network CNN. Therefore, by combining the base-GAN with the CNN, the generating network is continuously optimized, so that the DCGAN network model generates a house pattern diagram with a proper light source position.
In order to improve user experience and make the light source position more intuitive, the method for determining the light source position provided in this embodiment further includes: and determining the light source coordinates of the target house type graph according to the center point of the light source position of the target house. The calculated light source positions are a plurality of pixel matrixes at specific positions in the target house type graph, the pixel values around the pixel matrixes are 0, so that the accuracy of the calculated light source positions is improved, the specific installation position of the later-stage lamp is conveniently determined, and the center point of each light source position pixel matrix is calculated to be used as the light source coordinate of the target house type graph. According to the light source coordinates in the house type graph, the light source coordinates can be applied to the decoration design graph, and according to the light source coordinate positions, a light source is added to the light source positions in the 3D graph of the house, and a complete house decoration design effect graph is displayed through rendering of the light source.
In practical applications, referring to the flowchart of the method for determining the position of the light source shown in fig. 2, the method for determining the position of the light source can be used to generate the position of the light source in the house type map, and specifically, the method can be executed with reference to the following steps S202 to S208:
step S202: and acquiring a two-dimensional target house pattern diagram of the target house according to house information of the target house.
Specifically, all wall body and furniture information of the target house can be obtained by identifying the house type diagram of the target house, or the wall body information of the target house is drawn according to the analysis file of the existing house type diagram to obtain a complete outline diagram with house structure layout; drawing furniture in the target house in the profile diagram, according to the top view of all furniture and according to the specific positions of the furniture, taking the maximum just surrounding all parts of the furniture as a standard, using rectangular blocks to represent and replace all furniture, abstracting all furniture information, and omitting the detail information because the specific furniture profile and texture have smaller influence on the light source position; although the detail features of the furniture can be abstracted, the furniture height has a great influence on the determination of the position of the light source, so that the heights of all furniture are converted into gray rectangular blocks with different shades to be represented, the darker the color of the rectangular blocks is, the higher the height of the furniture is represented, and in this way, the 3-dimensional furniture information can be converted into two-dimensional image information. Taking the house type diagram of the house A shown in fig. 3 as an example, by identifying the house type diagram of the house A, obtaining all wall and furniture information of the target house, and obtaining a two-dimensional target house type diagram of the house A according to furniture arrangement information and furniture size information of the house A, wherein the two-dimensional target house type diagram of the house A is shown in fig. 4.
Step S204: the DCGAN network model is trained using training images.
The training images are house type drawings and known light source positions in the house type drawings, wherein the house type drawings comprise wall information, door and window information, outline information, furniture position information, furniture height information and furniture shape and size information of houses. The specifications of the training images are unified, and a house type graph without a light source (also called a two-dimensional target house type graph) and a house type graph with a light source (the house type graph refers to a graph obtained through data drawing, data supplementing and data conversion) can be combined to form the training images; all training images may also be adjusted to the same size, e.g. 640 x 640 resolution.
Step S206: inputting the two-dimensional target house type graph into a pre-trained DCGAN network model, and generating the house type graph with the light source position based on the DCGAN network model.
Taking the two-dimensional target house type diagram of the house a shown in fig. 4 as an example, the two-dimensional target house type diagram of the house a is input into a trained DCGAN network model, the house type diagram with the light source position of the house a shown in fig. 5 is generated, and gray dots (other colors such as red) in fig. 5 are the generated light source positions.
Step S208: and determining the light source coordinates in the target house type graph based on the house type graph with the light source positions.
And extracting the light source position from the generated house type map with the light source position to obtain the house type map with the light source position, and comparing and dividing image pixels of the house type map with the light source position by adopting a threshold method according to the color channel to obtain all the light source positions. For example, when the generated light source positions are red dots, the furniture and the house outline are gray with different shades, the light source is red, and the contrast segmentation of the image pixel points is performed by adopting a threshold method, so that all the light source positions are obtained. The above-mentioned light source position is actually a pixel matrix at a specific position, and the coordinates of the light source, that is, the specific coordinates of the lighting, are determined by calculating the center point of the light source position. Taking the house type diagram with the light source position of the house A shown in fig. 5 as an example, comparing and dividing the image pixel points by a threshold method to obtain all the light source positions in fig. 5, and calculating the center point of the light source positions to obtain the house type diagram with the light source coordinates of the house A, such as the house type diagram with the light source coordinates shown in fig. 6.
According to the method for determining the light source position, three-dimensional information in house information is converted into the two-dimensional target house type graph, influences of furniture size, height and placement positions in the target house on the light source position are fully considered, the DCGAN network model obtained through training and the light source position result obtained according to the DCGAN network model are more attached to the actual condition of the target house, and the rationality and accuracy of light source position determination are improved.
