Television control method capable of identifying child user and system thereof

Abstract

The invention discloses a TV control method and system for identifying children users, which relates to the field of electronic technology, and comprises the steps of taking pictures of N shooting moments within a preset time, the first camera and the second camera simultaneously shooting images containing human body Synthesize N three-dimensional stereoscopic images from the images; extract the human body contour in each of the N three-dimensional stereoscopic images and obtain the distance information of the human body corresponding to the human body contour; at least one human body corresponding to the human body contour When the distance information is less than the preset distance, face recognition is performed on the image containing the human body captured by the first camera or the second camera, and if it is recognized as a pre-stored child user, the TV is controlled to execute the pre-stored child protection instruction. The invention is used to identify technical defects such as small detection range and large environmental impact of the TV control method in the prior art. The binocular camera can realize rapid identification of user identity and distance information, and provide corresponding preset protection strategies for child users.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a television control method and system for identifying children users. Background technique [0002] With the development trend of electronic products such as intelligent terminals, televisions have become an indispensable household appliance in the family. There are various and exciting TV programs, especially for children. Become a loyal user of TV, but most parents often let their children watch TV as a means of obtaining their own free time due to work, housework and other reasons. The long-term lack of supervision on children's TV watching habits makes it easy for children to develop the habit of watching TV at close range, causing damage to children's eyesight, and thus adversely affecting their learning and life during their growth. Therefore, in terms of user requirements for smart TVs, child protection has become an important basis for measuring smart TV standards. ...

Problems solved by technology

Although this invention calculates the distance between the user and the TV, due to the use of infrared detection for the user’s distance perception, due to the poor infrared penetration, the infrared radiation of the human body is easily blocked and difficult to be received by the sensor. When the ambient temperature and When the temperature of the human body is close, the detection sensitivity drops significantly. In addition, the false alarm rate of the infrared detector has a great relationship with the installation location and method
