In order to ensure the monitoring effect, it is usually chosen to arrange video equipment in as many positions and angles as possible, such as erecting equipment beams and columns on the top of each corner of the environment, on the top of the wall, and in densely populated areas. Install, check and verify the overall monitoring system screen, if there is any omission, move or install the camera, so as to finally achieve the result of high coverage requirements. However, this method requires continuous drawing evaluation, verification, and adjustment. The construction time is long and the hardware cost is high, so it is necessary to provide a better method to reduce the construction time and hardware cost

The invention provides a BIM-based traction substation auxiliary monitoring image inspection registration method. The method comprises the steps of obtaining three-dimensional data of a substation BIMmodel and hardware parameters of various types of video equipment; importing the three-dimensional data and the hardware parameters into a three-dimensional visualization platform; pre-installing video equipment on the three-dimensional visual platform according to the installation specification of the substation, and configuring hardware parameters of the video equipment; adjusting the central front view angle direction of each video device to enable the video device to reach the widest view field; analyzing whether the video equipment has a visual angle blind area or not through rotation and zooming operations; if the video equipment has the visual blind area, adding the video equipment in the visual blind area according to the installation specification, and configuring hardware parameters of the video equipment according to the size of the visual blind area; recording position information of each piece of video equipment on the three-dimensional visualization platform and adjacentsubstation equipment; and adding a prefabricated video equipment model into the BIM model according to the position information, assigning values to the video equipment model, and then outputting animplementation scheme.
Description
technical field [0001] The present application relates to the technical field of construction design, in particular, to a BIM-based registration method for auxiliary monitoring images of traction substations. Background technique [0002] At present, when monitoring equipment is installed in large places such as substations and railway stations, it is generally designed by adding the position of the camera to the CAD drawing (construction drawing or as-built drawing) of the building plan, and delineating the approximate visible range. . In order to ensure the monitoring effect, it is usually chosen to arrange video equipment in as many positions and angles as possible, such as erecting equipment beams and columns on the top of each corner of the environment, on the top of the wall, and in densely populated areas. Install, check and verify the overall monitoring system screen, if there is any omission, move or install the camera, so as to finally achieve the result of high c...
