| 摘 要： | 本文针对工业摄影测量中高温锻件上的反射标志提取方法进行了探讨,提出绿激光投射到锻件上并提取标志中心点的方法,通过摄影采集绿激光标志图像并提取分析,验证此方法相比于用Canny算子和椭圆拟合算法提取所用的时间减少三分之二,与V-STARS摄影测量系统比对后,精度近0.039像素,初步满足了中精度工业摄影测量的要求。

| Abstract: | The location method of reflecting mark on the high temperature forging in the industry photogrammetry was studied in the paper.A method of centre location was proposed.Through the photographic collection and analysis,some experiments proved that the method was 2 times faster than Canny Ellipse fitting method and the accuracy was better 0.039 pixel than V-STARS photogrammetry system.The method could satisfy the basic need of photogrammetry and would produce practical value. |
