Localization method for dangerous distance from ground objects to wires in transmission line corridor
In order to accurately locate the dangerous distance between ground objects and wires in a transmission line corridor,a method for locating the dangerous distance between ground objects and wires in the transmission line corridor was proposed.LiDAR was used to obtain point cloud image data and filtering method was used to eliminate image noise.By using gradient calculation and phase grouping,the linear edge position of target image was detected,and the abnormal distance points were extracted.Global detection of abnormal distance between poles and towers was achieved through global peak values,and a safety distance evaluation model was established using grey correlation analysis method to locate the dangerous distance between ground objects and wires in the transmission line corridor.The test results show that the average reserved error value of the fault tolerance space for abnormal distance localization of this method is 0.3 m,the average error value of abnormal localization is 0.26 m,and the average localization accuracy is 98.9％,by which can improve the accuracy of dangerous distance localization from ground objects to wires in the transmission line corridor.
