Is the blue light only work as a symbolize depth sensing working?

Each time I use depth viewer, under the left camera will have a blue light. Is that true for zed 2i camera using two camera for stereo matching? Is the blue light a depth sensing camera?
Is there any details about the depth sensing principle?

Hi @dians
the blue led only indicates that the camera is operating, it’s not used by the Depth processing algorithm.
You can turn it on and off by using ZED SDK API commands:
C++/Python

I found that, after compare RGB and Depth image, the Depth image is a cropped version of left RGB(which close to the blue light), what is the reason?
I mean the Depth image will include a black vertical bar because of some “Visual blindness”?

That’s to be expected. The depth perception is present only in the overlapping areas of the left and right fields of view.
