摘　　要：为满足摄影测量中相机检校的需要,选用一种室内相机检校场的精密测量方法与实验分析方法,对相机检校场进行检校。根据山东科技大学室内三维检校场中标志点的排列规则,点数众多的实际分布特点,选用高精度的经纬仪测量系统,选取最佳的仪器和基准尺摆放位置对检校场内的标志点进行测量。利用统计检验的方法对标志点点位的稳定性进行分析,判断出标志点稳定可以满足相机检校的需要。In order to meet the needs of digital camera calibration in photogrammetrie. Choose an indoor digital camera calibration method of precision measurement and experimental analysis to measure camera control for calibration. According to the virtual distribution characteristic of marked points on 3D camera calibrating network in SDUST, Using theodolite measurement system for measurement of three dimensional coordinates of points. Make a measurement by choose a best position of instrument and reference meter. Make a precision analysis by theory of statistical test. Then judge the stability can meet the demand of digital camera calibration.
