Example Embodiment

[0046] The present invention will be described in detail below with reference to the drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation mode and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0047] The laser fence has a short distance and small angle deviation due to the mechanical deformation of the fixed end (such as thermal expansion and contraction) after a long time operation outdoors. However, since most of the previous position offset calibration uses manual methods, the efficiency is low, and the problem cannot be solved in time, leading to serious consequences. Such as figure 1 with figure 2 As shown, this embodiment implements an image capture-based system for correcting the position of a laser fence at the periphery of a substation. The laser fence at the periphery inclu...

Abstract

The invention relates to a substation perimeter laser fence position correction system and method based on image capture. The position correction system comprises control devices, three-dimensional holders, diode verification devices and image capture devices, wherein the three-dimensional holders, the diode verification devices and the image capture devices are connected with the control devicesrespectively. Each diode verification device comprises a laser diode and a photosensitive sensor, wherein the laser diode and the photosensitive sensor are arranged on two adjacent fence vertical rodsrespectively. Each image capture device comprises a camera and a reference object with point light sources. The cameras are arranged on the fence vertical rods. The reference objects with point lightsources are fixedly arranged at positions 30 cm from the vertical rods. The three-dimensional holders match the fence vertical rods. The fence vertical rods are vertically arranged on the three-dimensional holders. The control devices control the movement of the three-dimensional holders according to the feedback results of the diode verification devices and the image capture devices to correct the position of the fence vertical rods. Compared with the prior art, the system provided by the invention has the advantages of high correction efficiency, timely correction and the like.

Description

Technical field [0001] The invention relates to the technical field of substation perimeter protection, and relates to a substation perimeter laser fence, in particular to a system and method for correcting the position of the substation perimeter laser fence based on image capture. Background technique [0002] At present, a large number of laser fences are used in the safety monitoring of substations, which are necessary devices to prevent foreign objects from intruding and protecting equipment. However, even if the existing fence adopts a retractable fence bracket fixed on the work site, long-term outdoor operation will cause positional deviation due to factors such as deformation of the base, water accumulation in the device, and unstable expansion and contraction, resulting in the acceptance of laser fences. If the other party's signal is not available, an error alarm is generated. The traditional laser fence position correction is done by manual means, the work efficiency ...
