Aiming at the problem of image mosaic distortion caused by radial distortion, this paper proposes a method which introduces a single parameter division model into image mosaic. In this method, Harris operator is used to extract feature points, and the single parameter division model is used to correct radial distortion. A normalized cross-correlation method is utilized to complete preliminary matching, a random sampling consistent algorithm is used to improve matching accuracy, and the splicing process is completed according to matching relationship. The simulation results show that the method can be deployed quickly, and the heavy calibration process is saved. It is suitable for correcting the radial distortion caused by various types of cameras, which can realize the image mosaic without distortion. It provides a reference for the research of advanced driving assistance system and sky eye monitoring system.
