Embodiment Construction

[0035] A reliable detection method for missing children with low power consumption, using infrared sensors to conduct initial inspection of human objects; after initially detecting suspicious objects, start the camera again, and use the video object review method to confirm whether there are missing children, through the double-layer detection mode , can not only reduce system power consumption, but also reduce the false alarm rate and missing alarm rate of missing child detection, thereby improving the reliability of missing child detection.

Abstract

The invention relates to a missing child detection method based on human body detection. In the case of very low power consumption, human body targets are initially detected using an infrared sensor. After a suspected target is found through initial detection, a camera is started, and whether there is a missing child is confirmed using a video target re-checking method. Through a double-detection mode, the power consumption of the system is reduced, the false alarm rate and missing alarm rate of missing child detection are reduced, and the reliability of missing child detection is improved.

Description

technical field [0001] The invention relates to a method for detecting missing children and belongs to the technical field of video surveillance. Background technique [0002] In recent years, there have been many child fatal accidents caused by missing children on school buses, which has aroused strong social concern. In order to prevent such accidents, in addition to regular safety education and supervision and inspection of the relevant responsible persons and children in the car, it is also necessary to improve the ability to discover and warn missing children technically. With the rapid development of computer vision technology, the human body detection technology is becoming more and more mature. The patent "Status Recognition and Danger Control System for Occupants Stuck in the Car" (No. CN201510779628.0, 2015) detects whether there are passengers on the seat through the pressure sensor Legacy, this detection method cannot distinguish between people and objects, nor ...
