Embodiment 1
[0085] This embodiment provides a white balance synchronization method, such as figure 1 shown, including the following steps:
[0086] S1. Obtain the pixel ratio and pixel position mapping relationship of the key camera and the synchronous camera.
[0087] In this embodiment, the key camera and the synchronous camera may be different cameras arranged on the same side of the same shooting terminal. Wherein, the shooting terminal may be a mobile phone, a tablet computer, a video camera, a camera, a notebook computer and other devices. The key camera and the synchronous camera are set adjacent to each other on the shooting terminal, and the light source information corresponding to the two should be the same at the same time. It can be understood that multiple cameras can be installed on the same side of the shooting terminal, and one of the cameras with a moderate focal length and no obvious distortion is selected as the key camera, and the other cameras are used for synchron...
Embodiment 2
[0127] This embodiment provides a white balance synchronization system, such as Figure 6 As shown, the system 10 includes:
[0128] A priori module 11, used to obtain the pixel ratio and pixel position mapping relationship of the key camera and the synchronous camera;
[0129] The target image acquisition module 12 is used to acquire the key target image collected by the key camera and the synchronous target image collected by the synchronous camera, the key target image and the synchronous target image are images collected simultaneously for the same shooting target;
[0130] White balance processing module 13, carries out white balance processing to key object image;
[0131]Target region extraction module 14, for extracting the target region of interest from the key target image;
[0132] Mapping area extraction module 15, for obtaining the target mapping area corresponding to the position of the target region of interest from the synchronous target image according to th...
Embodiment 3
[0161] This embodiment provides an electronic device, which can be expressed in the form of a computing device (for example, it can be a server device), including a memory, a processor, and a computer program stored on the memory and operable on the processor, wherein the processor The white balance synchronization method provided in Embodiment 1 can be realized when the computer program is executed.
[0162] Figure 7 A schematic diagram of the hardware structure of this embodiment is shown, as Figure 7 As shown, the electronic device 9 specifically includes:
[0163] At least one processor 91, at least one memory 92, and a bus 93 for connecting different system components, including the processor 91 and the memory 92, wherein:
[0164] The bus 93 includes a data bus, an address bus, and a control bus.
[0165] The memory 92 includes a volatile memory, such as a random access memory (RAM) 921 and / or a cache memory 922 , and may further include a read only memory (ROM) 923...
