| 摘 要： | 以平面图形为观察对象，利用透视投影变换进行多角度的观察，将变换的结果与相机拍摄的具有相同角度的图片进行比较。来研究平面图形的三维观察效果。在透视投影变换过程中。像素点会发生重合和分离的情况，前一种情况可不考虑，对后一种情况利用插值作了处理。实验获得了良好的效果。这表明利用透视投影变换进行的多角度的观察，可以得到三维物体各个角度的概貌，从而实现三维物体的重构。

| Abstract: | In order to research the three-dimensional observation result of plane graphic,this paper takes it as observation object and observes it from different angles by perspective projection transformation.Then the result of the transformation is compared with the photos taken by camera from the same angle.In the transformation,pixels may be superposed or be separated.The first case is neglected and the second is processed by interpolation.A good result is obtained and indicates that the three-dimensional object is observed by perspective projection transformation, and we can get the whole appearance feature of the three-dimensional object, and then reconstruct the three-dimensional object. |
