Problems solved by technology

However, in the actual operation site of the substation, the access passages in the substation are too long, and it is basically impossible to completely close them. When the site is large and there are many operating sites, there are insufficient on-site safety monitoring personnel, and it is difficult to monitor the operating area in real time, which increases the safety risk

Embodiment

[0032] Example: see Figure 1-Figure 3 .

[0033] A substation operation object and target positioning method based on the fusion of infrared and visible light, using the visible light and infrared sensor system deployed on-site in the substation to collect on-site images in real time, using a distributed image processing platform, after denoising, fusion and enhanced preprocessing, Further, target and background segmentation and target feature extraction are carried out to detect on-site intrusion targets, and then dynamic target identification, positioning and tracking are carried out.

[0034] In the process of identifying, locating and tracking the above-mentioned dynamic target, it is mainly divided into three stages, including: dynamic target detection and recognition based on 3D scene and multi-spectral image fusion, target positioning based on multi-eye camera and target based on 3D scene Tracking, and the corresponding algorithm prototype is given; the dynamic target...

Abstract

The invention discloses a positioning method of a working object and a target of a substation based on infrared and visible light fusion. The technical scheme is as follows: by using a visible light and infrared sensor system deployed in the substation site, real-time images are collected, and a distributed image processing platform is used to remove the noise, fuse and enhance the pretreatment, then the target and the background are segmented, target features are extracted to detect a site intrusion target, and then dynamic target identification, lactation and tracking are performed. It is divided into three stages: dynamic target detection and identification based on 3D scene and multi-spectral image fusion, target location based on a multi-camera and target tracking based on a 3D scene,and a corresponding algorithm prototype is given. The invention adopts a fusion method based on a three-dimensional scene model, utilizes the spatial corresponding relationship between visible lightand infrared images to transform, solves the fusion problem under the condition of large field of view and multiple angles, obtains a better effect, and obtains more complete and reliable image information.

Description

Technical field: [0001] The invention relates to a substation on-site operation positioning method, in particular to a substation operation object and target positioning method based on the fusion of infrared and visible light. Background technique: [0002] At present, the on-site safety control of the substation adopts the method of manual observation. When the substation is working, there will be a safety supervisor to observe the situation of the work site in real time, observe whether the on-site staff keeps a sufficient safe distance from the live equipment, and use safety fences in the work area of ​​the substation. method to control the working area. However, in the actual operation site of the substation, the access passages in the substation are too long, and it is basically impossible to completely close them. When the site is large and there are many operating sites, there are insufficient on-site safety monitoring personnel, and it is difficult to conduct real-...
