Problems solved by technology

[0003] (1) The current reduction of construction land leads to the reduction of equipment spacing. Due to the lack of precise sensing and positioning technology and methods, the construction difficulty of live work near the substation is increased, and the safe operation space is reduced;
[0004] (2) The working space of the urban line channel becomes crowded, and there is a lack of active dynamic identification and judgment of non-contact safety distance;
[0005] (3) The sensing sensitivity and distance accuracy of the existing distance sensing devices based on field strength theory on the market are greatly affected by voltage, electromagnetic field, and transmission environment medium
[0006] To sum up, due to the current unfavorable target positioning and identification supervision, the safety production situation of substations is severe, with high incidence of personal casualties and equipment damage accidents
Although a variety of detection algorithms have been developed for dynamic object perception detection, most object perception methods based on deep learning rely on a large number of annotation labels, require a lot of work, and are not suitable for and uncooperative spatial objects. And the versatility of these algorithms needs to be further improved, and the accuracy and robustness of the algorithms are not strong enough to quickly and accurately lock the target and calculate the state and category parameters of the dynamic target in a complex environment
In addition, the extraction of different feature values ​​often only focuses on the information of a certain aspect of the image, and cannot express the target more comprehensively.
[0007] For the above problems, no effective solution has been proposed
