Method for actively tracking and monitoring infants and realization system thereof

Abstract

The invention discloses a method for actively tracking and monitoring infants, which firstly detects movement regions; then extracts smaller candidate regions including human face and hand or the like, and then detecting human faces. The method matches the detected faces, extracts the contour of the human face to be detected, and calculates the distance d between the middle point of the central connecting line of eyes of the contour and the geometric center of the chin and the area s of the surrounding region of the nose contour. A linear resolution analysis method is utilized to find out the best projection direction w capable of distinguishing between infant faces and non-infant faces. The distance d and the area s are projected in the direction w, and according to the projected points the baby value which expresses the human faces to be detected close to the infant characteristic is obtained. A middle point of two individual central connecting lines is taken as a threshold value K which distinguishes non-infant face and infant face. Whether the target to be detected is an infant or not is judged through comparing the baby value with the threshold value, if so, then taking the target as a track object. The invention also provides an embedded realization system for actively tracking infants.

Description

Technical field: [0001] The invention relates to the field of image information processing, in particular to a method for actively tracking and monitoring household infants and its embedded hardware implementation system. Background technique: [0002] The application of intelligent video processing technology in the monitoring field is constantly expanding. The existing video monitoring system for infants and young children in the home environment generally uses a camera to connect to the network through a PC, or directly connects to it in the form of an independent network camera. to the network. These devices generally have detection functions such as motion detection and static detection. Although what have has a cloud platform, it can be manually controlled by a preset point or the user at the client end (such as a browser) to rotate to the moving infant. But existing this type of household monitoring system has the following shortcoming in actual use: the user can't ...

AI Technical Summary

Problems solved by technology

But existing this type of household monitoring system has the following shortcoming in actual use: the user can't monitor infants and young children on the client terminal for a long time, and the camera can only monitor infants and young children in a place with a fixed viewing angle, so there is no need to monitor infants and young children. It can automatically track and shoot the moving infants in the family in real time, and cannot achieve the purpose of intelligent care and alarm

However, its camera is not loaded with a gimbal, so it cannot rotate from multiple angles, and it does not have the function of automatically identifying and selecting infants and young children in the scene and tracking them
