Line-scan camera calibration: a robust linear approach

Nettet1. des. 2013 · To test the proposed method, we use NED's NUCLi7300 line scan camera and RODENSTOCK's Grandagon-N lens for calibration. According to the specification supplied by the manufacture, the focal length of the lens is 90 mm and the resolution of the line camera is 7300 × 3, with unit cell size of CCD sensor being 10 μm × 10 μm.A 300 … NettetThis 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. rubys dress shop darlington
