When a user is in front of the television, an image acquisition device of the television acquires real-time position information of the target user according to a preset frequency under the control of a television system; the preset frequency is the frequency of acquiring the position information, which can be set by a person skilled in the art according to needs. For example, the preset picture capturing frequency is once every 5 minutes, so that the picture capturing apparatus will capture the position information of the target user once every five minutes, and calculate the amount of change between the position information of the target user captured at the fifth minute and the position information of the target user initially captured, the amount of change between the position information of the target user captured at 10 minutes and the position information of the target user captured at the fifth minute, and so on.

Wherein:

Further, step S13 in embodiment 2 above further includes:
and step S133, calculating the height of the target user and the horizontal distance from the target user to the terminal based on the ground view angle of the terminal camera and the ground view angle of the image.
Specifically, combining the calculation results of step S131 and step S132, the formula for calculating the height of the user object to be photographed is:
so far, the formula for calculating the horizontal distance between the height of the shot target user and the camera is as follows:
wherein, theta3And theta4Is two longitudinal visual angles, theta, corresponding to the target user to be photographed5The method comprises the steps of representing a transverse visual angle of a target user (as shown in fig. 7), calculating the transverse visual angle of the target user relative to a terminal camera through fixed parameters of the camera, calculating a longitudinal visual angle of the target user by combining a pixel distance from the bottom of the target user to the bottom edge of an image in image information of the target user obtained by shooting of the terminal camera, and calculating another ground visual angle of the target user through the fixed parameters of the terminal camera and a distance from the head of the target user to the bottom edge of the image in the image. Wherein sin is sine triangleThe function cos is a cosine trigonometric function and tg is a tangent trigonometric function.
In conclusion, the initial height value h of the target user can be calculated0Initial horizontal distance d0. And then calculating and comparing whether the h value and the d value in the subsequent set time period are changed or not, detecting whether the target user needs to be reminded of getting up to do exercise or not, and avoiding the health problems of lumbar vertebra and cervical vertebra caused by long-time sitting immobility.
In addition, in other embodiments of the present invention, the height of the target user and the distance from the terminal may also be obtained by other measurement calculation methods, and the present invention is not limited thereto. For example, the height of the target user and the horizontal distance from the terminal can be measured and calculated by using ultrasonic waves, a position sensor and the like.
In the embodiment, based on the perspective geometric relationship between the ground angle corresponding to the target user shot by the fixed camera provided by the television and the projection of the center of the camera, the height and the distance of the target user to be shot are converted into the ground view angle of the image by using a correlation algorithm, and the height of the target user to be shot and the horizontal distance from the camera are determined according to calibrated known parameter values. If the user gets up and walks within the set sedentary reminder calculation time, the height and distance values obtained by the camera in combination with the algorithm will change. Based on this, whether to remind the user to get up and go to rest in due time can be detected according to whether height and distance value change in this time quantum to realize the sedentariness prompt facility.
Further, step S20 described with reference to fig. 5 further includes:

To a certain extent, whether the user moves or not is determined by calculating the variation of the information of two adjacent positions of the target user, so that the situations that the target user moves slowly and slightly small movements are omitted can be avoided.
Further, the step 30 of the above-mentioned embodiment further includes:
step S301, if the variation of the two adjacent position information exceeds a preset range;
step S302, timing is restarted to detect whether the relative variation between any two adjacent position information in the preset time length is within a preset range.
Specifically, in this embodiment, the television system determines the location information of the target user according to the target user image collected according to the preset frequency, and determines that the target user does not move during the period when the variation of the two adjacent location information is within the preset range, but detects that the user moves during the period when the variation of the two adjacent location information exceeds the preset range; for example, taking a preset time length of 30 minutes and a preset frequency of 5 minutes as an example, when the variation between the position information at 5 minutes and the initially acquired position information does not exceed a preset range, it is determined that the target user does not move within 0-5 minutes, and then it is calculated whether the variation between the position information of the target user acquired at 10 minutes and the position information of the target user acquired at 5 minutes exceeds the preset range, and so on, until the variation between the position information of the target user acquired at 30 minutes and the position information of the target user acquired at 25 minutes does not exceed the preset range, it is determined that the user does not move within the 30 minutes, and at this time, the terminal prompts the user to avoid permanent damage to the physical health; however, if the variation of the position information of the target user collected at the 20 th minute and the position information of the target user collected at the 15 th minute exceeds the preset range, it indicates that the target user has moved for movement within 5 minutes, namely, within the 5 minutes from the ground to the 20 th minute, the television system will restart timing with the position information of the target user at the 25 th minute as the initial position information, that is, in this case, the period for detecting whether the user is moving is the 25 th to 55 th minutes, and the user will be prompted to sit for a long time if and only if the variation of the 6 adjacent two position information does not exceed the preset range.
In this embodiment, when the variation of the two adjacent position information exceeds the preset range, timing is restarted to detect whether the variation of the two adjacent position information within the preset time length is within the preset range, and then a sedentary prompt is given to the target user. The sedentariness action of the user is prompted more intelligently and timely, and the harm to the body health of the user due to sedentariness is avoided.
