| 摘 要： | 实验环境下检校的相机主距在外界作业环境下产生微小的改变.围绕主距变化对模型点坐标产生的影响展开讨论,得出主距改变对不同像点的影响不是等值的.而且主距越长,模型点之间的距离就越短,主距越短模型点之间的距离就越长.因此在作业过程中,若出现特殊情况使主距有明显变化的过程,必须对摄影机主距进行重新测定.

| Abstract: | The camera principal distance calibrated under the experimental from the outside world may produces small changes.The purpose of this study is research of principal distance changes effect on model.The result showed the model change caused by principal distance was not equivalent,and the longer the principal distance,the shorter the distance between model points.The shorter the principal distance,the longer the distance.The authors suggest if special circumstances make changes in the principal distance it m... |
