Camera Calibration Techniques in IP Camera

Most commercial cameras have a number of factory distortions, the which must be calibrated. Camera calibration consists of calculating the internal parameters of the camera focal length, position of the principal points, pixel skew and distortion coefficients) and is usually Carried out by computer applications that establish geometric relationships between objects and projections calibration in CCD cameras. Radial distortion can cause the position at a point in the photo to change from the actual location, so that the spatial and geometric quality is reduced. To get accurate spatial information from a photo taken by the camera, each type of correction must be given, one of the which is camera calibration. Camera calibration is a process to Determine the inner orientation elements and lens distortion of an object. In this research, it is an IP VISION LS / LSMB2200C camera with a resolution of 1280 x 720. The calibration method used is Self Calibration from Matlab.
