This approach requires an … 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. bobwhite\\u0027s 20NettetThis paper presents a new calibration method of line scan camera model based on cross-ratio invariance using a calibration pattern on the top of the gauge block. Instead of using the 3D pattern, planner pattern with precise motion platform, or pre-calibrated matrix camera, only a planner pattern with gauge blocks is used in this new method. cloak rand
