Problems solved by technology
Usually, the design of video surveillance projects is based on on-site drawings and manual site surveys to design monitoring points. Among them, site surveys are mostly judged by naked eyes based on personal experience, which cannot meet the current high-precision video surveillance design requirements.

The invention relates to an indoor video monitoring blind area identification method, which has the significance of providing monitoring probe point location field design assistance for video monitoring engineering designers by quickly calculating an indoor monitoring video blind area. The method is mainly used for auxiliary design of installation of video monitoring equipment in the security field. The method is mainly realized through the following steps of: installing an infrared emission device for simulating a camera shooting monitoring range according to a pre-designed monitoring point position. Infrared signals are received through continuous movement of infrared receiving equipment in space, and a video blind area is identified according to the signals. By using the method, the blind area of the monitoring point position can be quickly identified, the dynamic identification blind area of the field adjustment point position is supported, the method can be used for the fine adjustment design of the field monitoring point position, and the field point position design confirmation is assisted in the simplest and most intuitive way.
Description
technical field [0001] The invention relates to a method specially used for quickly identifying blind areas of surveillance video in the city. Background technique [0002] With the development of technology and the requirements of related fire protection, security, and anti-terrorism regulations, various buildings, especially public buildings, put forward higher requirements for the deployment of video surveillance systems, requiring surveillance videos to cover a wider monitoring area. Usually the design of video surveillance projects is based on on-site drawings and manual site surveys to design monitoring points. The site surveys are mostly based on personal experience and judged by naked eye observation, which cannot meet the current high-precision video surveillance design requirements. If a method can be used to effectively identify blind areas of video surveillance points, it can help designers improve design accuracy and design efficiency. Contents of the inventio...
