Human body object monitoring method for remote locations

Abstract

The invention relates to a human body object monitoring method for remote locations. In the method, a physical sensor is combined with image processing; a video collection device starts only when the physical sensor detects an invasive object; a human body object is further determined by utilizing a human body object verification method based on a video image; video collection, transmission and storage devices are closed if no human body object exists; a video monitoring system starts working if a human body object exists, and meanwhile continues detecting human body objects; the video monitoring system is closed if neither the physical sensor nor video image processing discovers an effective human body object. In the method, only the physical sensor with small power consumption works uninterruptedly, thereby effectively reducing system energy consumption; meanwhile the double test of the physical sensor and the video image processing enhances human body detection performances, reduces redundant data, and effectively increases other correlation analysis processing efficiency of a monitored video.

Description

technical field [0001] The invention belongs to the field of video image processing oriented to public safety early warning, and in particular relates to a human target monitoring method oriented to remote areas. Background technique [0002] Video surveillance is widely used in the field of public security, providing rich data support for public security organs to carry out early warning and case analysis. The power consumption of commonly used video cameras with visible light illumination is about 1.5-5W. When the infrared lighting function is turned on, the power consumption is about 15-45W. The sensor power consumption is generally below 0.5W. Existing video surveillance systems usually use all components to work 24 hours a day, and most remote areas do not always have human targets. The 24-hour working mode causes great energy waste, and the resulting large amount of redundant data, It also reduces the efficiency of analysis by relevant departments. Therefore, it is n...

Problems solved by technology

The existing patents basically implement the two types of methods in isolation. On the one hand, the human body detection performance is not optimal; on the other hand, it is not used to improve the working efficiency of the monitoring system, and energy-saving processing is not realized.
