AI Technical Summary

Problems solved by technology

However, the monitoring ability of ultrasonic ranging is limited, and it cannot monitor bad sitting postures such as tilting the head and shrugging shoulders; small gravity sensors also have the above shortcomings; and although 3D sensors and wearable devices can achieve better monitoring results, the cost is relatively high.

Embodiment 1

[0042] Provides a method of sitting posture monitoring such as figure 1 As shown, the method may include:

[0043] Step 101, collect the real-time sitting posture image of the user frontally;

[0044] Step 102, comparing the difference between the standard sitting posture image entered by the user terminal and the real-time sitting posture image to obtain a sitting posture judging result;

[0045] Step 103, providing the sitting posture judgment result to the user terminal.

[0046] In this embodiment, a dedicated camera can be used to collect real-time images of the user's sitting posture, or the front camera of a computer or mobile phone can be used to collect real-time images of the user's sitting posture, or a camera device embedded in other learning companion systems can be used to extract the sitting posture . Such a variety of hardware combinations can greatly reduce the cost of use.

Embodiment approach

[0047] In one embodiment, before obtaining the sitting posture judging result according to the difference between the standard sitting posture image entered by the user terminal and the real-time sitting posture image, the method further includes: calibrate the standard sitting posture and extract the key points of the sitting posture, thereby constructing the standard sitting posture model. As a preferred embodiment, the step of constructing a standard sitting posture model may include:

[0048] a. Carry out the following calibration on the standard sitting posture image entered by the user:

[0049] p1: left eye p2: right eye p3: nose p4: left mouth corner p5: right mouth corner p6: left shoulder p7: right shoulder, record pi, the connection line of pj is Lij;

[0050] b. Record the position of the center of the nose (key point p3) as C;

[0051] In this embodiment, the sitting posture can be judged by the parents or other supervisors, and the sitting posture model approved...

Embodiment 2

[0068] Such as figure 2 Shown, the present invention also provides a kind of sitting posture monitoring device, comprises:

[0069] Acquisition module 21, positively collects the user's real-time sitting posture image;

[0070] The judging module 22 obtains a sitting posture judging result according to the difference between the standard sitting posture image entered by the user terminal and the real-time sitting posture image;

[0071] The providing module 23 provides the sitting posture judgment result to the user terminal.

[0072] In order to provide accurate sitting posture judgment results, the judgment module 22 is also used for: standard sitting posture is calibrated to extract sitting posture key points, thereby constructing a standard sitting posture model; according to the key point position constraint authentication standard sitting posture; real-time sitting posture key points for calibration Soften the position; and classify the bad sitting posture to form a b...

Abstract

The invention provides a sitting posture monitoring method and device. The method comprises: collecting a real-time sitting posture image of a user on the front side; comparing the difference between the standard sitting posture image input by the user side and the real-time sitting posture image to obtain a sitting posture judgment result; and providing the sitting posture judgment result to a user side. The technical problems of limited monitoring capability and high cost in the prior art are solved.

Description

technical field [0001] The invention relates to a monitoring method based on image feature extraction, in particular to a method and device for monitoring sitting posture based on key point detection. Background technique [0002] Improper sitting posture can easily cause students' myopia and hunchback, and it also greatly increases the probability of suffering from cervical and lumbar diseases in adulthood, which greatly affects the quality of learning and life. Most parents have realized the importance of urging students to maintain correct sitting posture. However, due to the generally poor cognitive ability and self-control ability of primary and middle school students, they cannot maintain the correct sitting posture for a long time, and it is difficult for parents and teachers to supervise and remind them in time for their daily sitting posture. [0003] The existing sitting posture monitoring is generally realized by ultrasonic ranging, small wearable gravity sensors...
