Camera intrinsics extrinsics
WebJul 7, 2015 · Mapping depth pixels with color pixels The first step is to undistort rgb and depth images using the estimated distortion coefficients. Then, using the depth camera intrinsics, each pixel (x_d,y_d) of the depth camera can be projected to metric 3D space using the following formula: WebThe model generalizes across many lens types and is trivial to integrate into existing 3D reconstruction and rendering systems. Our key insight is to use an invertible neural …
