Is there a way to request dewarped images from the ImageServer? I'm trying to draw bounding boxes on a fisheye camera, but I want to match the dewarped image displayed on the smart client so that the boxes line up.

The answer is no. The image server can only give you the original image.

How should I map bounding boxes then? Is there a guide for sending bounding boxes on fisheye cameras so that they map correctly on the dewarped smart client view?

I just talked to my colleague regarding this question, but the answer is still no, there is no such a guide unfortunately. The only thing that you could do is to develop your own dewarping but it might be not so easy, we assume.
