针对近景摄影中传统的测量算法误差较大、计算过程较繁琐的问题,提出了一种新的测量算法———栅格空间量测法。该算法直接由标定点的像点构造一个理想的栅格量测空间,将感兴趣的物点通过其像点映射到该栅格量测空间,经与栅格网点的数据按距离进行融合后得出其定位值。最后通过实验对该算法进行了验证,结果表明:该算法的测量误差控制在忽米级,定位精度明显优于传统算法且计算简便。

Aiming at the problems in close-range photography that traditional photogrammetry has higher error and complicated calculation process,this paper presents a new photogrammetry called grid space measuration,which constructs an ideal grid measuring space directly by the image point from the calibra-ted point,then makes the interested physical point maps to the grid measuring space through its image point,finally gets its location value by fusion according to the distance with the grid data.Finally the ex-perimental result shows that the error can be controlled within centimillimeter level by using this algo-rithm,the positioning precision is superior to the traditional algorithm,and the calculation is simple.
