Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be described in detail below in combination with the accompanying drawings and implementation examples. It should be understood that the specific implementation cases described here are only used to explain the present invention, and are not intended to limit the invention.
[0038] (1) Installation and positioning of IVS equipment
[0039] The IVS camera needs to maintain a certain height difference from the ground as far as possible, and the entire substation perimeter should be placed within the scope of the camera's field of view, such as figure 2 shown.
[0040] During the installation of IVS, the three-dimensional space position of the equipment probe should be measured and positioned to obtain the three-dimensional space coordinate position of the IVS equipment, and ensure that the relative error between the spatial geographical locatio...

The invention discloses a transformer substation protection method based on positioning video dynamic target three-dimensional space calibration. The method comprises the following steps: (1) installing and positioning IVS equipment; (2) building a monitoring target information database; (3) enabling the IVS to monitor the semantization of the key target information and performing warehousing and call; (4) carrying out GIS vectorization and dynamic calibration on video dynamic target information; (5) dynamically monitoring attribute query of the target; (6) monitoring target tracking; (7) performing double perimeter protection. According to the method, long-term storage and 3DGIS presentation of video key information are realized by semantizing the IVS key information, and real-time calibration and double perimeter prevention of a video dynamic target in a three-dimensional space are realized by GIS vectorization of an IVS key dynamic target.
Description
technical field [0001] The invention belongs to the technical field of substation security, and in particular relates to a method for applying the three-dimensional space calibration to the perimeter protection of electric power substations based on the dynamic target analyzed by positioning video intelligent analysis. Background technique [0002] Existing substation security monitoring is usually based on one or more channels of ordinary video surveillance or with intelligent analysis function, and the existing perimeter protection video surveillance with intelligent analysis function exists alone or in a network. The existing technology does not semanticize and store the video analysis content, and cannot store the video content and key extraction information for a long time for correlation analysis; nor does it perform three-dimensional space calibration on the dynamic target trajectory in the video analysis, and cannot rely on geographic information Systematic means for...
