Zed2 depth data

[xiaohu-art]

hello, thank you for your work! I am going to run some custom data with your repo, and I use Zed2 camera to capture RGB-D images. I found the image from Zed2 is with shape (width, height, 4), but I don't know if this shape is correct or supported. Meanwhile, I print the depth data and cast it to np.uint16 but there is so many "nan" value, so I am again wonder if it is right.

the shape shape (width, height, 4) is the RGB image (with alpha). You need to get their depth image.
