Abstract

Due to the manufacturing, installation, and other reasons, the camera optical system can not work accurately according to pinhole imaging principles because of lens distortion. There exist optical distortion errors between the practical images of object in the camera imaging surface and ideal images of object. The distortion should be eliminated on occasion of images precise measuring and strict locating. This paper puts forward the basic principle of rectifying the system geometrical distortion errors using planar grid. Experiment results show that the method of rectifying the radial distortion and the tangential distortion put forward in this paper has obvious improved results.
