| 摘 要： | 本文介绍了一种多站点近景摄影测量系统，即通过使用近景摄影测量技术，在多个站点观测目标，可提高测量精度．该系统构建了一种简易控制场，采用基于共线方程式的解析处理方法，通过空间后方交会算法对系统进行标定，并通过多片空间前方交会算法解算目标的空间坐标．试验结果表明，在长宽高各3m的范围内，该系统的多个目标距离测量的平均中误差为0．07mm．

| Abstract: | A system used close-range photogrammetry technology and observed targets by multi-site to improve precision is introduced. It constructs a simple control field, and uses analytic disposal approach based on collinear equation, to implement system calibration by method of spatial resection, and compute spatial coordinate of targets by method of spatial intersection. The experimental results shows that, in the system, RMS of multi-target distance could be 0.07 mm in range of 3 m ×3 m × 3 m. |
