Description

I can running this project, now I want to use the camera matrix and depth map to calculate the 3D(X,Y,Z) point postition on the point cloud? Or a approximation value is OK. Thank you

Research direction

Start by tracing OpenSfM's camera-matrix and depth-map outputs and how they represent points in the point cloud. Determine whether they support mapping a 2D image point to a 3D position or only an approximation; done means documenting or implementing a reliable mapping approach.
