Projector-Camera calibration projector-camera v3a
Calibration method to find Gp=(camera coordinate system to projector to transformation) • Project a point xp in projector image to the projection frustum and the calibrated camera captures the handheld moving plane (4 corners) and the projected point Xc. • The camera coordinate system is the world coord. Sys. • The 4 corners define the handheld plane for display (). • The captured image point of Xc is xc’, which defines the vector VXc from the camera center to the point Xc. • Intersection between and VXc is Xc, hence Xc can be found. • xp=Gp *Xc, so if enough points (>=6, typically 40) correspondences between Xc and xp are given Gp can be found. projector-camera v3a
