Calibration of the intrinsic and extrinsic parameters of a camera as well as the lens distortion parameters is a crucial step in many camera-based vision applications. Further, ensuring the simple operation of the calibration process and the accuracy of the calibration results is critical. The calibration process of the line-scan cameras is more complicated when compared with that of the area-scan cameras. Herein, the imaging geometric model and the lens distortion model, which are suitable in case of line-scan cameras, are described; subsequently, the general calibration procedure of the line-scan camera is summarized. Furthermore, the calibration methods that have been previously proposed in the literature based on static imaging and dynamic scanning imaging are classified and analyzed, and their characteristics are briefly reviewed.
