How to project the 3D point to image？ #57

Closed GCQi closed 1 year ago

GCQi commented 1 year ago

I read the 3D point and intrinsic&extrinsic parameter from json file, and i want to project the 3D points to image plane, but the result is confusing. And I did not find a indruction about the coordinates system, could you tell me the define of different plane and the transformation about 3D plane and image plane?

Hi, we define the coordinates system on this page.

Hi, thank you for your excellent work. I have already read the document, but I am still confused about the reason for the first three coordinate changes. They change the coordinate frame from Waymo camera to Waymo camera, but I'm not sure what their purpose is.

Refer to offcial replay, we can project the 3D point in waymo coordinate.
