Proposal

I want to make sure wether the rgb image return by pyzed have distortion or not? If has distortion, how to diminish it? And is the 3d point map returned by pyzed API align to the image with distortion?

Use-Case

I want to calculate the radius of a round wood board accuratly, due to the 3d points of the edge is not stable. I calculate the fitted plane of the wood board first, then I project the pixel coordinate of the wood board edge back to the fitted plane. While, the radius value I got always bigger than real radius. The same thing happen when I calculate the distance of two points, which both lay on the board.

Thanks

Hi @JimXu1989,

When retrieving your image via the API, you can choose whether to retrieve the sl.VIEW.LEFT_UNRECTIFIED or sl.VIEW.RECTIFIED (here is the corresponding doc : sl.VIEW and retrieve_image) If you don't want "distortions" in your image, you will need to retrieve the sl.VIEW.LEFT

Thanks, so the example provide by stereolab, which use sl.VIEW.LEFT, already return left images without distortions, am I right?

@JimXu1989 yes exactly
