摘要
Abstract
The paper has introduced a model of radial distortion and eccentric distortion for array CCD camera and established the expand collinearity equation for calibration on non-measurable camera.Quaternion has been used to describe the attitude parameters.The mathematical model has been established for camera calibration based on unit quaternions.The rotation matrix is constituted of unit quaternions instead of Euler angels(ω,φ ,κ).The calibration experiments of small size array CCD camera have been done by using 3D control field indoors.We have acquired better orientation precision above 0.2 pixel.关键词
