Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an image capturing method for a camera according to an embodiment of the present invention, where the method is applicable to a situation where a field of view of the camera needs to be enlarged, and the method can be executed by an image capturing device of the camera. The method provided by the embodiment specifically comprises the following steps:
and step 110, receiving a starting request of the target camera.
For example, a plurality of cameras are installed on the electronic device, a camera opening option may be set in a control interface of the camera application program, the camera opening option may include one or more cameras among the installed plurality of cameras, and after any one camera is selected from the camera opening options, an opening request of the selected camera may be received.
For example, the default camera opening request may be received after the camera application is started.
And step 120, starting the target camera and at least one associated camera of the target camera.
For example, a control interface of a camera application program may be provided with associated camera setting options, where the associated camera setting options may include cameras in a camera opening option and selectable associated cameras corresponding to each camera, and an associated camera selected by a user from the selectable associated cameras corresponding to each camera is set as an associated camera of the camera.
For example, after the target camera to be turned on is determined, the associated camera of the target camera may be set. If a target camera is selected from the camera opening options, a related camera setting list can be popped up, all installed cameras can be listed in the related camera setting list, and the camera selected by the user in the related camera setting list is set as the related camera of the target camera.
For example, each camera may be provided with a default associated camera, and after receiving an opening request of a target camera, the target camera and the default associated camera of the target camera may be opened.
Therefore, after the starting request of the target camera is received, the target camera and the associated camera of the target camera can be started, the image information of different angles in the current scene can be acquired through the target camera and the associated camera, and the image information in a large view field range can be acquired through the integration of the image information acquired by the target camera and the associated camera.
And step 130, acquiring the image information of the target camera and the image information of the associated camera, and processing the acquired image information according to a preset rule to determine the target image information of the target camera.
For example, after the image information of the target camera and the image information of the associated camera are obtained, the image information of the target camera and the image information of the associated camera can be fused according to a preset image fusion algorithm, and the fused image information is used as the target image information of the target camera, so that after a starting request of the target camera is received, favorable information in the image information of the target camera and the image information of the associated camera can be extracted to the maximum extent to be used as the target image information of the target camera.
For example, after the image information of the target camera and the image information of the associated camera are acquired, the image information of the target camera and the image information of the associated camera are analyzed and processed respectively through a preset rule, so that better image information in the image information acquired by the multiple cameras is used as the target image information. For example, in a meeting scene, after the image information of any camera is acquired, the image information can be subjected to face recognition, and counting element information such as the number of human faces, the distance between the human faces and the center of the image, the size of the image pixels occupied by the human faces and the like in the image information, adding each element information according to the corresponding weight to obtain a decision value corresponding to the image information, the image information corresponding to the maximum decision value in the image information of the multiple cameras can be used as the target image information of the target camera, so that in a conference scene, after receiving the starting request of the target camera, the target image information of the target camera can be automatically switched between the image information of the target camera and the image information of the associated camera through a preset rule, and the visual field range of the target camera is further expanded, so that conference personnel can conveniently know the dynamic state of a scene in a larger visual field range in real time.
For example, the position information of the sound source can be acquired through the microphone array, for example, the angle of the sound source relative to the microphone array can be acquired, so that the corresponding relationship between the preset angle range and the camera can be stored, after the angle of the sound source relative to the microphone array is acquired, the camera corresponding to the angle can be determined according to the stored corresponding relationship between the preset angle range and the camera, and then after the target camera and the associated camera acquire the image information again, the image information of the camera corresponding to the angle is used as the target image information of the target camera, so that the target image information can be corresponding to the position of the sound source in real time. In a conference scene, the target image information can be corresponding to the image information of the speaker in real time, so that conference personnel can communicate conveniently.
The embodiment receives the starting request of the target camera; starting a target camera and at least one associated camera of the target camera; the method comprises the steps of obtaining image information of a target camera and image information of an associated camera, processing the obtained image information according to preset rules to determine the target image information of the target camera, starting the target camera and the associated camera after receiving a starting request of the target camera, obtaining the image information of a plurality of cameras, analyzing and processing the image information of the plurality of cameras to determine the target image information of the target camera, and further conveniently and intelligently expanding the visual field range of the target camera.
Example two
Fig. 2 is a flowchart of an image obtaining method of a camera according to a second embodiment of the present invention, which is further optimized based on the above embodiments. The method provided by the embodiment specifically comprises the following steps:
and step 210, receiving a starting request of the target camera.
Preferably, a plurality of cameras are installed in the electronic device, and an operating system of the electronic device is an android system.
Fig. 3 is a schematic structural diagram relating to a camera architecture in the android system. Wherein, the framework that relates to the camera in the tall and erect system of ann mainly includes: application layer (Application), Framework layer (Framework), Hardware Abstraction Layer (HAL), Linux Kernel layer (Kernel), and hardware layer (HW). When a certain camera is started or a parameter of a certain camera is set through a camera Application program in an Application layer, the Application layer calls an Application Programming Interface (API) provided by a framework layer, the framework layer calls an interface of a hardware abstraction layer, and the hardware abstraction layer correspondingly calls an interface of a Linux kernel layer, so that the camera on the hardware layer is driven to be started or the camera is set according to the set camera parameter. After the camera acquires the image information, the acquired image information is transmitted to the application layer sequentially through the Linux kernel layer, the hardware abstraction layer and the framework layer, so that the camera application program acquires the image information of the camera.
Preferably, the method provided in this embodiment can be executed at a hardware abstraction layer, and the hardware abstraction layer does not need to modify other layers when executing the method, and can be compatible with any third-party application program.
It should be noted that the method provided in this embodiment may also be implemented in other layers, such as an application layer or a framework layer.
After receiving a starting request of a target camera, simultaneously starting the target camera and at least one associated camera of the target camera so as to obtain image information of different angles in the current scene through a plurality of cameras.
And step 230, distributing corresponding buffer areas for the target camera and the associated cameras.
Preferably, after the target camera and the associated cameras are started, corresponding buffer areas are respectively allocated to the target camera and each associated camera, so that after each camera acquires image information, the image information can be cached in the corresponding buffer areas.
Illustratively, after the number of the images cached in the buffer area corresponding to each camera reaches the preset number of the images, the buffer area corresponding to each camera is cleared, or the buffer area corresponding to each camera is cleared at regular time to ensure that the subsequent image information can be timely stored in the corresponding buffer area.
And step 240, receiving a control instruction of the target camera.
For example, the camera may be controlled in the camera application, for example, parameters of the camera are set, the camera is controlled to start and stop, and the like, and after the camera application performs corresponding setting on the target camera, a corresponding control instruction of the target camera may be received. The parameters of the camera may include parameters such as resolution and frame rate.
And step 250, sending the control instruction to the target camera and the associated camera.
Preferably, after receiving the control instruction of the target camera, the received control instruction is sent to the target camera and the associated camera, so that the target camera and the associated camera are simultaneously controlled through the control instruction of the target camera.
If the received control instruction is a stop instruction, the stop instruction is sent to the target camera and the associated camera, so that the associated camera of the target camera is closed while the target camera is closed.
And step 260, caching the image information of the target camera and the image information of the associated camera into corresponding buffer areas.
When the target camera and the associated camera acquire the image information and return the image information, the returned image information can be received, and the received image information is cached to the corresponding buffer area.
And 270, acquiring the image information of the target camera and the image information of the associated camera, and processing the acquired image information according to a preset rule to determine the target image information of the target camera.
And step 280, if the image information of the associated camera is the target image information, the thread where the target camera is located acquires the image information of the associated camera from the buffer area of the associated camera for displaying.
When any camera is started, the thread corresponding to the camera is started so as to finish the operations of acquiring, sending or displaying the image information of the camera in the thread.
For example, if the preset rule is that image information obtained by fusing image information of a target camera and image information of a certain associated camera according to a preset fusion algorithm is used as target image information of the target camera, after the thread where the target camera is located obtains the image information of the target camera, the thread where the target camera is located can obtain the image information of the associated camera from a buffer corresponding to the associated camera, fuse the image information of the target camera and the image information of the associated camera according to the preset fusion algorithm, and return the fused target image information to the camera application program, so that the camera application program obtains the target image information and displays the target image information in a display interface of the target camera.
For example, if the image information of a certain camera is determined to be the target image information by a preset rule, the image information of any camera can be obtained from the corresponding buffer area through the image analysis thread after being cached to the corresponding buffer area, and analyzing the image information according to a preset rule, if the image information of a certain associated camera is determined to be the target image information according to the image information analysis result of each camera, since the image information cannot be returned to the application layer through the thread of the associated camera to display the target image information in the display interface of the target camera, therefore, after the thread where the target camera is located acquires the image information of the target camera, the thread where the target camera is located acquires the target image information from the buffer area corresponding to the associated camera, so that the target image information is returned to the camera application program through the thread where the target camera is located; if the image information of the target camera is determined to be the target image information according to the image information analysis result of each camera, the thread where the target camera is located can directly return the acquired image information of the target camera to the camera application program. Thus, the camera application may acquire and display target image information in a display interface of the target camera.
Preferably, the image information of the target camera and the image information of the associated camera can be acquired from the buffer area at intervals of a preset time through the image analysis thread, and the acquired image information is analyzed and processed respectively according to a preset rule, so that the image information is not required to be analyzed and processed after each frame of image information is returned by each camera, and the calculation amount is reduced.
The preset time interval can be set according to actual conditions, and can also be determined according to the frame rate and the preset frame number.
Preferably, after the image information of the target camera is returned to the camera application program, the buffer areas corresponding to the cameras are cleared, so that the image information in the buffer areas is cleared more timely, and the follow-up image information can be guaranteed to be timely stored in the corresponding buffer areas.
In the embodiment, the control instruction is sent to the target camera and the associated camera, so that the target camera and the associated camera are simultaneously controlled through the control instruction of the target camera; the method comprises the steps that corresponding buffer areas are distributed for a target camera and an associated camera, image information of the target camera and image information of the associated camera are obtained from the buffer areas at intervals of preset time, the obtained image information is processed according to preset rules to determine the target image information of the target camera, and better image information is determined to be used as the target image information of the target camera by utilizing the image information of a plurality of cameras; if the image information of the associated camera is the target image information, the thread where the target camera is located acquires the image information of the associated camera from the buffer area of the associated camera for displaying, so that the target image information is returned to the application layer through the thread where the target camera is located, and the target image information is displayed in the display interface of the target camera.
