摘要
从摄影测量原理出发,结合电力线测距的特点,分析了电力线的摄影几何,提出了相应的电力线位置确定策略及满足电力线实时测距要求的基于物方匹配的计算方法,并对实时测量的技术难点进行了分析。模拟实验和实际实验验证了此方法的可行性。
Based on the principle of photogrammetry,we analyze the features of the geometric conditions for photography of the power line.Then,a strategy to determine the locations of the power transmission line is proposed and realized,as well as one method that meets the requirements of real-time ranging based on object-space matching is extended.Also the technical problems of real-time measurement are researched.Finally,experiment results prove that this method is feasible and effective.
