【摘要】 本文探讨应用普通相机、普通设备进行精密近景摄影测量的方法。试验结果表明,在3、4m的摄影距离内,当布置了精度高于0.1 mm的高精度三维控制场,应用直接线性变换(DLT),解析计算精度可达到点位中误差为±0.35mm的要求;在10m内可达到±1mm的精度。由于使用的是普通相机,因此不但有实用价值而且容易推广。更多还原

【Abstract】 This paper is dealing with the application of ordinary cameras and equipmentsfor proceeding with the precision close range photogrammetry method. Accordingto the results of the experimentations, it is found that at the photographic dis-tance of 3-4 metres, when a high accuracy a-dimensional control area with accu-racy higher than 0.1mm having been arranged, and making use of direct lineartransformation(DLT), the analytic computation can reach toe mean square errorof points about ±0.35mm; and, within a distance of 10m, the accuracy canreach ±1mm. Due to the usage of ordinary cameras it has a practicality valueand will develop.更多还原
