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 auto

Embodiment Construction

[0039] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0040] (1) A method for actively tracking and monitoring infants and young children at home;

[0041] see figure 1 , the following are the specific steps:

[0042] (1) Video collection process: the system collects PAL or NTSC analog video signals from the camera.

[0043] (2) A / D conversion process: convert the digital video signal into YUV422 format through TVP5146 chip, store the video signal in SDRAM, access the collected data through FVID interface, and send it to DM6437 chip for specific processing Algorithmic processing. The resolution of the original signal collected by the system is 640×480, which is converted to 320×240 in order to improve the efficiency of the algorithm.

[0044] (3) Moving target detection: In order to adapt to th...

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 ...
