About multiple cameras

[yanrihong]

Dear authors, while reading the paper, I am very interested in the use of multiple cameras, especially in the part regarding the processing of camera outputs. I have the following questions:

When dealing with the RGB outputs of multiple cameras, how is the selection of RGB images achieved?
Is it based on certain specific criteria or algorithms to choose the RGB image of one particular camera,
or is there a fusion process for the RGB images from multiple cameras?
If it is a fusion process, what kind of fusion method is used?
