Hardware insulator positioning system, method and automatic maintenance system

Abstract

The invention provides a metal insulator positioning system, which is used for overhauling actuators. The metal insulator positioning system includes a monocular vision unit and a recognition and positioning unit. The monocular vision unit is used to obtain the image of the metal insulator including the marking unit, and the recognition and positioning unit is used. In order to obtain the pose of the hardware insulator in the coordinate system of the inspection actuator through the marking unit according to the image, the marking unit includes a plurality of marks for setting relative positional relationships. The invention also provides a metal insulator positioning method and an automatic maintenance system. The metal insulator positioning system, method and automatic maintenance system provided by the present invention, by setting two marks with the same shape and different sizes on the metal insulator, use the monocular vision unit to realize the positioning of the metal insulator, and only need the monocular vision unit to realize the positioning of the metal insulator. High precision positioning.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a hardware insulator positioning system, method and automatic maintenance system. Background technique [0002] With the expansion of demonstration and promotion of the new generation of smart substations, energy consumption and waste have been effectively reduced, and the performance of substations has been optimized. Among them, the isolated circuit breaker replaces the combined application of the traditional circuit breaker and the isolating switch, the maintenance requirements are greatly reduced, and it supports a leaner and more compact substation layout and higher availability, so it has been widely used. [0003] Although the reliability and stability of the isolating circuit breaker have been greatly improved compared with the previous circuit breakers and isolating switches, it is still necessary to arrange personnel maintenance in a timely manner. In addition to the pro...

Problems solved by technology

[0010] The second monocular vision solution has low positioning accuracy, mainly because the relative position of the camera and the target object changes greatly, and the outline of the target object to be measured is uncertain, resulting in a large range of calculation results.

[0011] However, for smart substations, the automatic maintenance system requires a low-cost positioning system that can position the metal insulators with high precision
