Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
As it is shown in figure 1, the object of present invention offer is industrial and the stacking method of Image model, it comprises the following steps:
S1: obtain the image in each face of object.
Wherein, the image of acquisition refers to the omnidirectional images of object.Such as, adopt with every 2 degree from horizontal direction with camera
Collect an image, 180 can be gathered；Then one image of every 30 degree of collections from top to base, the most total about can adopt
Collect 1080 images, cover the image in (360 degree of orientation) in a lot of orientation of object.
S2: obtain the cloud data of each image by image processing software after being processed by described image.
In this step, it is sharpened by the described all images collected use Photoshop image processing software,
Relatively color, take off the end etc. and process, be then passed through a cloud three-dimensional software and generate a cloud data for object；Described cloud data includes three-dimensional seat
RGB color information on mark and each some cloud.
S3: according to described cloud data production cloud model, thus obtain the texture mapping of point cloud model.
In this step, according to described cloud data with the RGB color information on each some cloud by software Agisoft
PhotoScan Pro software (threedimensional model reconstruction software) processes the point cloud model generating object, on each some cloud of model
There is RGB color information, therefore can be obtained by the model texture mapping of this point cloud model.
Described step S1 to S3 is the process of the optical grating point cloud model obtaining object.
S4: obtain the laser scanning threedimensional model of object.
Wherein, the laser scanning threedimensional model detailed process obtaining object includes: by using handheld laser scanner
HandyScan carries out the scanning of comprehensive (360 degree) and acquires the three-dimensional mesh data of object object, is then passing through

This step is the acquisition methods of the laser scanning threedimensional model obtaining object, and it walks with the acquisition of optical grating point cloud model
Suddenly (S1 to S3) does not has sequencing.
S5: obtain the seat of laser scanning threedimensional model and the same characteristic point of the object different parts of model texture mapping
Mark.Such as, described coordinate is three-dimensional coordinate, that is to say XYZ coordinate.
S6: described coordinate is overlaped and obtains the three-dimensional data image with texture color of object.
In this step, owing to being same object, the model obtained by different methods, laser scanning is obtained
Model is coordinate data, not RGB color information；And due in point cloud model each some Yun Shangdou include RGB face
Therefore two models are carried out overlapping merging by color information, it is possible to clearly obtain the texture mapping of object.That is to say and first choose
The different parts of object, then corresponding with texture mapping selects object same position respectively at laser scanning three-dimensional module
Characteristic point, overlaps the characteristic point merging at same position, thus finally by software Geomagic Studio software
By two model combinations together, thus obtained the high-precision, with the three-dimensional data image of texture color of object.
As in figure 2 it is shown, present invention also offers the overlapping system of the industry of a kind of object and Image model, including:
