Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The invention aims to solve the problem that the prior television control method needs to input the identity information of infants in advance before use, so that the operation of a user is inconvenient, and provides a method and a system for controlling the on-off of a television screen, wherein the main technical concept is as follows: when the television is started, detecting a human body signal within a viewing range according to a preset time interval, and acquiring an infrared image of a target human body after the human body signal is detected; and judging whether the target human body is an infant or not according to the target human body distance and the target human body imaging size in the infrared image, if so, controlling the television to pause playing the current program and closing the television screen.
Specifically, an infrared signal detection unit may be disposed on the television for detecting a human presence or movement signal within a certain range; when a user watches the television, the infrared signal detection unit detects human body signals within a viewing range every five minutes to ten minutes, after the human body signals are detected, the infrared signal detection unit acquires infrared images of a target human body and sends the acquired infrared images to the control unit, the control unit calculates the height value of the target human body according to the target human body distance and the target human body imaging size in the infrared images and calculates the head-to-body ratio of the target human body, wherein the head-to-body ratio is height/head height, and then the age stage of the target human body is jointly judged according to the height and the head-to-body ratio. And when the height and head-to-body ratio data judge result is that the infant is the infant, the television system automatically pauses the program being played and closes the television screen.
Examples
The method for controlling the on and off of the television screen, disclosed by the embodiment of the invention, as shown in figure 1, comprises the following steps:
step S1, when the television is started, detecting human body signals within the viewing range according to a preset time interval, and acquiring infrared images of a target human body after the human body signals are detected;
the human body signals and the infrared images in the viewing range can be detected and acquired through an infrared detector. The infrared thermal imaging technology has the advantages of high detection precision and long distance.
When the television is in an open state, the infrared detector detects human body signals within a viewing range at intervals, after the human body signals are detected, infrared images of a target human body are obtained, the infrared thermal imaging technology receives heat generated by metabolism of all parts of the human body to form images, and the human body signals can be accurately positioned by infrared detection because the body temperature of the human body is higher than that of surrounding objects.
The preset time interval may be 5 minutes or 10 minutes, which may be different according to actual situations.
And step S2, judging whether the target human body is an infant or not according to the target human body distance and the target human body imaging size in the infrared image, and if so, controlling the television to pause playing the current program and closing the television screen.
The specific method for judging whether the target human body is an infant or not according to the target human body distance and the target human body imaging size in the infrared image may include:
calculating the height and the head height of the target human body according to the target human body distance and the target human body imaging size in the infrared image, calculating the head-body ratio of the target human body according to the height and the head height of the target human body, and judging whether the target human body is an infant or not according to the height and the head-body ratio of the target human body.
Specifically, before the television leaves the factory, the data of the height range and the head-to-body ratio range commonly used in each age group can be stored in the television terminal system, so that the television terminal system is convenient to use later. For example, the height range of an infant of 0-1 year old is set to 45-80 cm, the head-to-body ratio range is set to 3.5-4, the height range of an infant of 1-3 years old is set to 70-110 cm, the head-to-body ratio range is set to 4-4.5, the height range of an infant of 3-6 years old is set to 90-140 cm, and the head-to-body ratio range is set to 4.5-5. The height range of the adult is set to be 140cm-200cm, the head-body ratio range is set to be 6-8, and the like.
When a human body signal is detected, the height value of the target human body is calculated according to the target human body distance and the target human body imaging size in the infrared image, the head-to-body ratio (height/head height) of the target human body is calculated, and the age stage of the target human body is jointly judged according to the height and the head-to-body ratio. For example, when the human body thermal imaging is detected, the height is 78cm, the head height is 19cm, the head-to-body ratio is 80/20-4.1, and the infant is determined to be in the age interval of 1-3 years; and simultaneously, when a second thermal imaging is detected, the height is 160cm, the full head height is 22cm, the head-body ratio is 160/22-7.27, the head-body ratio falls within the range of adults, and the adults are judged.
And when the infant is judged, controlling the television to pause playing the current program and closing the television screen.
After the television screen is closed, the infrared detector continues to detect according to a preset time interval and preset times, and if the target human body is judged not to be an infant according to the target human body distance and the target human body imaging size in the infrared image, the television screen is opened and the television is controlled to continue playing the current program.
After the television screen is closed, the infrared detector continues to detect according to the preset time interval and the preset times, and if no human body signal is detected after the preset times are detected, the television is controlled to enter a dormant state.
In order to improve the accuracy of the determination, in this embodiment, the method may further include: receiving a height range and a head-to-body ratio range preset by a user, and judging whether the target human body is an infant or not according to whether the height of the target human body is in the preset height range or not and whether the head-to-body ratio is in the preset head-to-body ratio range or not.
In this embodiment, a page may also be provided in the television system setting for the user to select whether to turn on the infrared detection function, so as to implement the turning on and off of the television screen on and off control method described in this embodiment.
Based on the above technical solution, an embodiment of the present invention further provides a system for controlling on/off of a television screen, as shown in fig. 2, including: the infrared signal detection unit and the control unit;
the infrared signal detection unit is used for detecting human body signals within a viewing range according to a preset time interval when the television is started, and acquiring infrared images of a target human body after the human body signals are detected;
the control unit is used for judging whether the target human body is an infant or not according to the target human body distance and the target human body imaging size in the infrared image, and if yes, the television is controlled to pause playing of the current program and close the television screen.
It can be understood that, because the sharing device of the internet of things data according to the embodiment of the present invention is a device for implementing the sharing method of the internet of things data according to the embodiment, for the system disclosed in the embodiment, since the sharing device corresponds to the method disclosed in the embodiment, the description is simple, and for relevant points, reference may be made to the partial description of the method.
