Abstract

The invention discloses a method and a device for reminding poor postures based on depth images. The method comprises the following steps: monitoring each frame of depth image in a video shot by a Kinect camera, and calculating the trunk bending degree of a human body in the current depth image; when the trunk bending degree is greater than a first threshold value, determining the current depth image to be poor posture images; when the trunk bending degree is smaller than or equal to the first threshold value, calculating the neck bending degree of the human body in the current depth image; when the neck bending degree is greater than a second threshold value, determining the current depth image to be the poor posture images; calculating the specific value of the quantity of the poor posture images in preset time and the total quantity of the depth images in the preset time; and when the specific value is greater than a third threshold value, giving out a hint. The method has the characteristics of low cost, simple algorithm, small calculated quantity, accurate calculation, high efficiency and the like, and can be preferably popularized and implemented in practical application.

Description

technical field [0001] The invention relates to the technical field of posture correction, in particular to a method and device for reminding bad sitting posture based on depth images. Background technique [0002] Sitting posture not only affects the growth and development of teenagers, but also has great significance for office workers. Real-time sitting posture judgment is of great significance for developing good habits and protecting health. In real life, in addition to achieving the purpose of developing healthy sitting habits through human observation and correction, there are more typical methods based on wearable devices, artificial intelligence and deep image analysis. [0003] Among them, the method based on wearable devices needs to install sensors on multiple joints such as the waist, which is likely to cause a decrease in human comfort, and the cost is very high; currently, most of the behavior analysis methods based on artificial intelligence use LSTM for dee...
