Determination of Three-Dimensional Camera Parameters with the Information on Two-Dimensional Plane for 3D Measurement

抄録

The camera parameters of each camera must be determined to demand the three-dimensional coordinate of the object in image from a stereo image. The determination of the camera parameters is the most important calibration work for a highly precise measurement. The determination of eleven linear camera parameters needs the information of more than six points of the coordinates in space (x, y, z) and the corresponding camera screen projection coordinate (X, Y). The set of those six points must include three-dimensional structural information (six points must not on same plane). In this research, a theoretical method to determine eleven camera parameters from four points of information in the plane and focal length of the camera lens is developed.
