摘　　要：结合激光点投影和激光测距仪,开发了精确测量桥梁病害的透视畸变校正算法。使用四个激光点获取校正图像所需的参数,对高精度单反相机采集的桥梁病害图像进行校正,从而获取病害真实参数。试验证实了四点校正法的可行性,可从采集到的不同角度的桥梁病害图像中获取正视图对应的参数。The perspective distortion correction algorithm for the accurate measurement of bridge diseases is developed by combining the laser point projection and laser rangefinder.The images of bridge diseases collected by the high-precision DSLR camera are corrected by using the four laser points to obtain the parameters required for image correction,so as to obtain the true parameters of diseases.The feasibility of the four point correction method is confirmed by the experiment,and the parameters corresponding to the front view are obtained from the images of bridge diseases collected from different angles.
