全景体视图自动方程

在体视结构中,视点、景物以及画面三者间相对位置的任何改变均会引起体视图的变异,本文建立的自动方程,含有11个可变参量(6个景物参量、3个视点参量、2个画面参量),适当地控制这些参量,即可绘制出所希望的全景体视图。实现了:(1)景物姿态随意变换;(2)全景跟踪观察;(3)画面可置于空间任意位置。至此,彻底地解决了单画面全景体视图的算法。本文还初步实现了复合画面全景体视图,将对全景体视图的更深入研究及开拓应用起到推进作用。

THE AUTOMATIC EQUATION OF PANORAMIC STEREOGRAPHS

In stereo-structure, any changes of the relative position of sight point, scenery and picture plane can lead to variation of stereograph. The automatic equation presented in this paper includes eleven variable parameters, that is, six scenery parameters, three sight point and two picture plane ones. The desired panoramic stereographs can be established by means of the proper controlling of these parameters. The graphs thus drawn have the following three characteristics, (l)The posture of the scenery can be changed at will; (2)The panoramic observation can be done by means of tracing; (3)The picture plane can be placed anywhere if necessary. The paper also tries to fulfil the multi- picture plane panoramic stereographs.
