Abstract

The invention provides method and system for accurately positioning a polling target of a transformer substation. The method comprises the steps of determining a polling target; guiding a polling robot to reach the polling target; adjusting an image according to the task load, and adjusting the position of a holder; calculating the deviation of a polling target center in the sampling image center; slightly adjusting the position of the holder according to the deviation to obtain a clear target image. With the adoption of the method and system, the accuracy and precision of positioning the polling target can be improved.

Description

technical field [0001] The invention relates to a precise positioning method and system, in particular to a precise positioning method and system for substation inspection targets. Background technique [0002] Visible light cameras, infrared thermal imaging cameras and other substation inspection robots are equipped with task load systems to detect abnormal appearance of substation equipment, identify abnormal temperature and identify abnormal instruments. However, due to factors such as the precise positioning error, heading error, and gimbal rotation error of the inspection robot itself, the precise positioning of the task load system is inaccurate, causing the detection target to be out of the image field of view or deviate from the center of the image, making it difficult to obtain high-resolution, high-definition images. High-degree images directly affect the accuracy and accuracy of substation equipment detection results. [0003] The invention patent with the applic...
