Abstract

This invention discloses a human body target nighttime monitoring method. According to the method, an active infrared lighting camera is utilized to acquire a nighttime image; after the nighttime image is preprocessed, a human body feature template is utilized to extract out candidate regions; and a method according to which a histogram of oriented gradient (HOG) is adopted as a feature to be extracted, and a liner support vector machine (liner SVM) is adopted as a classifier, is utilized to realize nighttime human body detection. Based on the optimization of an intelligent detection algorithm in a nighttime environment, around-the-clock and all-weather intelligent monitoring of a mobile platform can be realized.

Description

technical field [0001] The invention belongs to the technical field of monitoring, and in particular relates to a night monitoring method for a human body target. Background technique [0002] The monitoring system plays a role that cannot be underestimated in terms of safety protection and crime prevention. At present, most of the traditional unit or community security monitoring systems use fixed cameras and use manual observation for monitoring. This system has disadvantages such as being greatly affected by personnel factors, insufficient deterrence, and blind spots in vision. Therefore, it is an important direction for the future development of intelligent monitoring systems to develop mobile monitoring robots to replace manual 24-hour uninterrupted patrols and to automatically alarm when abnormal conditions occur. [0003] At present, the camera system with night vision capability is relatively mature, and the passive infrared camera is relatively expensive, and there...
