Monitoring system and method for preventing watching TV from close quarter based on set top box range finding

Abstract

The invention discloses a monitoring system for preventing watching TV from a close quarter based on set top box range finding. The system comprises a set top box, an infrared inductor, a minitype camera, an image processing center, and a decision center. The set top box is foundation of the whole monitoring system, and provides physical equipment and computing power. The infrared inductor using passive infrared and using a human body as an infrared inducing source is used to monitor whether a viewer exists in an induction scope and trigger the camera to start. The minitype camera is used to collect images and send the images to the image processing center. The image processing center using face recognition technology and image range finding technology analyzes the images sent by the camera. The decision center carries out corresponding strategies according to analysis and process results of the image processing center and a local timer. An embodiment of the invention also discloses a method for preventing watching TV from a close quarter based on the set top box range finding. The method can flexibly and intelligently carry out corresponding strategies according to practical situations, and prevent asthenopia or even visual impairment of the viewer caused by watching TV from a close quarter for a long time.

Description

technical field [0001] The invention relates to the technical field of digital home, in particular to a monitoring system and method for preventing short-distance viewing of TV based on distance measurement of a set-top box. Background technique [0002] Along with popularizing of television set, watching TV has become an indispensable part in people's daily life. However, the rays radiated from the picture tube of the TV can consume a large amount of rhodopsin in the retina. If you watch TV continuously for too long in a room with poor lighting, it will easily lead to visual fatigue and significantly reduce the eyesight of the TV watcher. In order to reduce the damage to human eyes caused by the rays radiated by the TV, the distance between the TV and people should be 4 to 6 times the diagonal of the screen. [0003] The vast majority of children like to watch TV, but they often approach the TV unconsciously, and because of lack of self-control, they will watch TV at clos...
