Research on techniques for geometric calibration of three fields push-broom-type sensor

The paper combines with three fields push-broom-type sensor, which is independently developed by Shanghai Institute of Technical Physics, Chinese Academy of Sciences, and with the use of full color light source, reflected mirror, rotating table, parallel light tube, image acquisition software, computers and other laboratory equipment to create a geometric calibration method. The method aimed at three fields’ push-broom- type sensor imaging system, and we can get the geometric calibration raw data. The geometric calibration method can provide a method to establish an image mosaic model, and provide basic data for the geometric correction[1] about image distortion.
