this information 110° (H) x 70° (V) x 120° (D) max. regards the raw frames provided by each single CMOS sensor.
The final FoV after image rectification is a little smaller, you can retrieve this information real-time from the CameraParameters data structure of the ZED SDK: C++/Python.
Please do not consider the global FoV created by stitching the left and the right images. The camera is designed to overlap the frames the most as possible to be able to perform the stereo-matching processing on the maximum available FoV. For this reason, a stitched image would result in an image with a FoV slightly bigger.
On a video, I have a final fov of 92.8°. Instead of the initial 110°
Is the center of the final fov aligned with the fov of the left lens ?
In that case, we “lose” 8.6° in the left of the image, and 8.6° in the right of the image.
Or is it biased and can we lose more of one side of the image ?
The rectified left image is centered in the optical center of the left lens.
The rectified right image is centered in the optical center of the right lens.
So you lose ~4.3° on the left and ~4.3° on the right of each image.
