| 摘 要： | 摄像机水平扫动，垂直扫动，旋转和放大等操作造成的几帧图像之间着坐标变换，证明了这些坐标变换构成一个投射群，同时对透射模型进行精确的定量分析，确定了适合该模型的参数取值范围。许多有趣的现象可以用数学分析清晰地解释。

| Abstract: | The precise quantity analysis for the projective model which estimating the coordinate transformation between pairs of images,taken with a camera that is free to pan,tilt,rotate about its optical axis,and zoom is presented. The valid domains of the parameters in the model are determined. Many interesting phenomena (for example,the image will disappear if the camera is on a plane to which the camera faces) can be clearly explained by our mathematical analysis. |
