AI Technical Summary

Problems solved by technology

For example, observe the user's eyes. If the user's eyes cannot be captured by the camera, it will be judged that the user's writing height is lower than the normal height value. If the duration of this situation exceeds a predetermined value, it will be judged that the user's writing is too close, which is harmful to the eyes.
Although this method is simple, due to the individual differences of users, it is difficult to accurately set the height of the sensor or camera to capture local features such as eyes. If the height of the sensor or camera is not set properly, the result of judging the sitting posture will be inaccurate
In addition, the sensor has strong radiation, which will cause great harm to the user's body

Embodiment 1

[0039] Such as figure 1 As shown, a smart desk lamp includes a desk lamp body (not shown in the figure), a camera 10 , a control module 20 , and a reminder module 30 . The desk lamp body at least includes basic structures such as a base, a bracket fixed on the base, a light bulb set on the bracket, and a power supply set in the base. From the perspective of energy saving, the light bulb can be an LED light bulb. The desk lamp body can be a general desk lamp, and this embodiment does not limit its structure.

[0040] The intelligent desk lamp also includes a camera 10 , which can be fixed on a bracket or installed on a base, and is used to collect video images in a preset area, and send the collected video images to the control module 20 . The preset area includes the user's head, neck, shoulders, etc. In order to collect images of the upper body of different users, the camera 10 is preferably installed on the base of the desk lamp and faces the upper body of the user obliquel...

Embodiment 2

[0064] Compared with Embodiment 1, the smart desk lamp of this embodiment can not only realize myopia sitting posture warning, but also realize the function of fatigue state reminder. It can judge whether the user is tired by detecting blinking or yawning, and reminds the user to take a rest in time when the user is tired, which can further help the user prevent myopia.

[0065] In some embodiments, the control module 20 is also used to identify human eyes according to the received video image, and calculate the number of eye blinks in the video image within a preset time period. If the number of eye blinks exceeds a preset threshold, it is determined that a fatigue state has occurred. And control the reminder module 30 to output reminder information.

[0066] Specifically, the control module 20 uses preset OpenCV library functions to perform image recognition after receiving the video images collected by the camera 10 to identify the positions of human eyes.

[0067] Blink d...

Embodiment 3

[0077] The embodiment of the present invention also discloses a sitting posture detection method, comprising the following steps:

[0078] S01. Generate a human body contour map of the user according to preset rules according to the collected video images of the user in a preset area, where the preset area includes the user's head, neck, and shoulders.

[0079] In the embodiment of the present invention, the contour of the human body can be obtained by using the background difference method or the frame difference method. Take the inter-frame difference method as an example to explain as follows:

[0080] (1) Perform median filter preprocessing on the image first to remove random noise in the image.

[0081] (2) Select the background image Bx(x,y) from the video image so that it only contains the background image.

[0082] (3) Select two consecutive frames of images from the video image, the previous frame is recorded as Pk-1(x,y), and the current frame is recorded as Pk(x,y...

Abstract

The invention discloses an intelligent table lamp. The table lamp comprises a table lamp body, a camera, a control module and a reminding module, wherein the control module is used for receiving a video image acquired by a camera, generating a human body profile diagram of a user according to a preset rule, judging the positions of a head and the shoulders, calculating the difference between the positions of the head and the shoulders, judging that a myopia sitting posture occurs if the difference meets a preset threshold value, and controlling a reminding module to output reminding information. The intelligent table lamp calculates the relative positions of the head and shoulders of the human body through the control module to judge whether the sitting posture of the user is accurate or not. The sitting posture detection method overcomes the sitting posture detection error caused by inconsistent requirements of individual difference on the height of the camera when specific features such as eyes or mouth of a user are directly collected. The lamp has the advantages of high sitting posture detection accuracy, strong practicability, safety, reliability and the like, and can well help the user to prevent myopia. The invention further discloses a sitting posture detection method and electronic equipment.

Description

technical field [0001] The invention relates to the technical field of intelligent electrical appliances, and mainly relates to an intelligent desk lamp, a sitting posture detection method, and an electronic device. Background technique [0002] According to news reports, the myopia rate of Chinese teenagers ranks first in the world: the myopia rate of Chinese high school students and college students has exceeded 70%, and it is increasing year by year, and the myopia rate of primary school students is also close to 40%. In contrast, the myopia rate of American elementary and middle school students is only 10%. Among the three major factors inducing myopia (genetics, environment and nutrition), scientists believe that environmental factors play a greater role in the occurrence of myopia, among which, incorrect sitting posture (including improper writing distance) is the key factor affecting the user's vision , it is necessary to use appropriate technical means to remind the...
