Abstract

The invention relates to a rapid image recognizing method of a power tower pole outline. The method comprises the following steps: (1) converting a shot color image into a gray level image through brightness calculation, and carrying out smooth denoising on the image; (2) based on an improved Harris angle point detecting method, realizing the detection to power tower pole pixel in an outline image of a known area shape; (3) firstly gridding the image, and subsequently calibrating the power tower pole pixel by adopting a gridding angle point density clustering algorithm through the clustering to the angle point density; and (4) calibrating and outputting the power tower pole pixel. By detecting a pole tower area in the image, a small range area for detecting various members can be provided; detailed capital construction data of each pole tower are backed up and can be checked in power departments; specific positions and numbers of various members in the image can be extracted accurately based on the information, and moreover the intelligent diagnosis to normal faults of various members can be further realized.

Description

technical field

[0001] The invention relates to a pattern recognition method developed by computer vision technology, in particular to a fast image recognition method for the outline of a power tower. Background technique

[0002] For a long time, most of the work of installation, operation, maintenance and overhaul of transmission lines in my country has been mainly done by manpower, and the level of mechanization is far behind the international advanced level. With the emergence of high-voltage, high-power, and long-distance transmission lines, the transmission lines are getting farther and farther away from cities and main traffic roads, making their construction, operation and maintenance more and more difficult. The development of modern aviation industry and automation technology provides new technical methods and means for the construction and operation and maintenance of transmission lines. Automated inspection of areas that are difficult to reach by manpower by mea...
