Along with the rapid development of digital image gathering and processing technology, image has become an important way for people to gain information, and it has also become an important content of the image processing to make the correlation evaluation using the image information to the product geometry information. This article studies geometric rectification and perspective projection rectification.Space Coordinate Localization in Large Space Stakeout Environment Based on Single CCD. Camera is to use CCD camera as the probe,and make the images in the watch scene input into the computer,then using the algorithms of image processing,calculate the space position of the object. This thesis try to syncretize computer vision,computer graphics and digital image processing,using the reference point image of obtaining from CCD camera (four points being square), the image will be analyzed and processed, the image can be reconstructed,calculate the space position of the object.For reducing price of project in the fact, introduce CCD camera with a large-field,gain image of geometry distortion and perspective projection. Camera calibration is the tradition way,using it to analyze ,but it has too many parameter to calculate make it not to apply in fact. This thesis make the image do distortion and perspective projection correction , reconstruct the image. Establishing model of image coordinate and space coordinate based on the corrected image,it can calculate the space position of the object. In this paper,we present a rectification method of Geometric rectifycation by applying the theory of beeline has been beeline, it improves efficiency, the result shows that the method is reliable and valid, we present a rectification method of perspective projection by applying the theory of forming vanishing point.Based on all have been researched, the thesis brings forward an overall design for the system. The experiment results show the system has the good feature ofveracity and reliability.
