technical field [0001] The invention belongs to the field of high-voltage line detection data processing, and relates to a high-voltage line chain point and the entire chain track processing that can analyze the position of the high-voltage line and realize the stable output of the high-voltage line track by analyzing and processing the radar echo data of the high-voltage line method. Background technique [0002] At present, there are not many researches on high-voltage line data processing technology. Most of them are research on high-voltage line detection itself. Due to the characteristics of high-voltage line targets themselves, the track processing of group target tracking is similar to the processing of high-voltage line track. The following articles indicate this field background technology: [0003] Geng Wendong's "Research on PDA-Based Group Target Merging and Separation Method" published in "Signal and Information Processing" 2007 Radio Engineering.

This may also be related to the small application range of this technology, and the related group tracking technology cannot be directly applied to high-voltage line types, and the processing effect on high-voltage lines is not ideal.

[0006] Current problems: analysis and detection of high-voltage line position and high-voltage line track processing

Moreover, the drawing of high-voltage lines cannot be interrupted. The lack of intermediate points will inevitably seriously affect the quality of the entire high-voltage line. However, the inevitable shaking of the helicopter during flight and the occlusion of unknown objects will cause individual high-voltage line points to flicker. This also requires us to use the track processing algorithm to compensate for this short-term point loss phenomenon and maintain the complete display of the high-voltage line
