Abstract: Based on the characters of the line scan camera and the vehicle-borne 3D data acquisition system, it presented a method which is for the calibration of the scan line camera (SLC) based on the laser scanner. The SLC has many advantages, such as high frequency and wide view angle, which is better than a frame digital camera in saving images and getting a complete image. But it also has a same problem: lens distortion. SLC and LS are two important parts of the the vehicle-borne 3D data acquisition system. It uses SLC to grab the color texture information of the objects, and uses the LS to get the 3D coordinate information of the objects. The two sensors have a common character: during the acquisition the LS data is a line which is made up with discrete points and the SLC data is a color line. Base on this character it presented a method which is for the calibration of the scan line camera (SLC) based on the laser scanner. Using the angle information from the original laser scanner data, combing the principle of the scan line camera, it built a calibration model for SLC and designed some experiment method for that. Then it computed high precision calibration parameters, which provides basis for the texture mapping in the future and gives references for the similar sensors calibration.
