The application research on digital camera calibration with MatLab and photoshop

The digital camera calibration is a digital camera to determine the parameters of internal and external parameters of the process. The purpose of calibration is to establish three-dimensional objects in the world coordinate system and image coordinates relations. The calibration method is usually photogrammetry traditional equipment calibration method, the direct linear transformation method, short perspective transformation and least square method. These methods are available through Matlab and photoshop End auxiliary procedures.
