摘要
传统摄影测量是基于测点的前方交会和后方交会,所以共线方程(即物点、像点与摄影中心位于一条直线上)是整个摄影测量的核心。相对定向和绝对定向则基于同名像点共面的思想,而在工业计量测量和飞机姿态测量等领域,大量存在的是一些直线或者曲线,并不存在明确意义的点。因此,提出了基于广义点的相对定向和绝对定向的方法,解决了传统相对定向和绝对定向不能解决的问题,理论上证明该方法是可行的。
Traditional photogrammetry was based on forward intersection and resection using survey point, so collinear equation (object point, image point and center of projection lie in a line) was the kernel of the whole photogrammetry, and relative orientation and absolute orientation were based on ideology of coplanar corresponding image point. But in the field of industry metrological measurement and aircraft attitude measurement, there were baselines or curves, but not the definitude point. So this article brought forward the method of relative orientation and absolute orientation based on generalized point, which resolved the problem that the traditional relative orientation and absolute orientation could not do. The method was proved feasible in theory.
