摘要:

针对双相机工业摄影测量系统不同应用场景下实测精度与标称精度不匹配的问题,对系统网形结构进行了深入研究。通过研究发现:当物方测量点交会角大于45°,测量点与基线水平夹角介于28°~68°,竖直视角不超过23°,且测量点位于双相机工业摄影测量系统纵深方向[0.4B,1.3B]范围内时,测量点的精度较高,超过该范围,测量点的误差将变大。本文基于以上结论提出一种采用双相机工业摄影测量系统对测量场内规定位置标准尺长度测量,通过比较标准尺测量值与标称值差异,快速评定系统测量场精度的方法。试验表明,该方法能够快速准确地评定双相机工业摄影测量系统测量场精度,对于保证系统现场作业质量,提高现场作业效率具有重要指导作用。

Abstract:

In response to the issue of mismatch between nominal accuracy and actual measurement accuracy in different application scenarios of the binocular stereo industrial photogrammetry system, in-depth research was conducted on the mesh structure of it. It has been found that if the intersection angle of the measurement points is large than 45°, the horizontal angle between measurement points and baseline among 28°and 68°, vertical viewing angle less than 23 °, and the distance between the measure points and the baseline among 0.4B and 1.3B, the measure points' accuracy is high. If the measure points out of this range, the uncertainty of the points measurement will increase. Based on the above conclusions, a method has been proposed that use a binocular stereo industrial photogrammetry system to measure the length of a scale-bar at specified positions within the measurement field. By comparing the difference between the measured values of the scale-bar and the nominal value, the accuracy of the system's measurement field can be quickly evaluated. Experiments have shown that this method can quickly and accurately evaluate the measurement field accuracy of the binocular stereo industrial photogrammetry system, which plays an important guiding role in ensuring the quality of on-site operations and improving the efficiency of on-site operations.

Key words: binocular stereo industrial photogrammetry system, measuring field, calibration, scale-bar
