Web19. feb 2024 · The projection matrix is used to convert world space coordinates into clip space coordinates. A commonly used projection matrix, the perspective projection matrix, is used to mimic the effects of a typical camera serving as the stand-in for the viewer in the 3D virtual world. WebThis method estimates a perspective projection matrix using SIFT (Scale-Invariant Feature Transform) and obtains the 3D shape of a non-planar surface using POC (Phase-Only Correlation) [38,39,40,41].
