Nettetcamera calibration. The traditional approaches use a set of checker-board images taken at various positions and exploit planar geometry to estimate the calibration parameters. PMD camera calibration: Since PMD cameras are relatively new, most of the current approaches borrow heavily from traditional cam-era calibration technique. Nettetalgorithms dealing with plane-based calibration have inherited their motivation from one of these approaches. Direct Linear Transform (DLT) This calibration procedure consists of two steps. In the ﬁrst step the linear transformation from the object coordinates (x j,y j,z j) to image coordinates (u ij,v ij) is solved.
