Sit-up detection system and method based on human body and skeleton key point recognition

Abstract

The invention discloses a sit-up detection system and method based on human body and skeleton key point recognition, and the system comprises an image collection module which employs a high-definitioncamera to collect a video image of a testee; the image recognition module which is used for extracting human skeleton key points of the testee in the continuous frames; the action detection module which is used for detecting the change condition of an included angle formed by a straight line formed by the waist key points and the shoulder key points and a relative horizontal position of the skeleton key points of the human body of the testee in the continuous frames to judge whether the testee lies down or sits down or sits down; the judging and counting module which is used for judging and recording the frequency of completing sit-up of the testee within the testing time; and the data display module which is used for displaying the frequency of sit-ups completed by the testee within thetest time. The method is high in detection speed, low in cost and suitable for single-person or multi-person detection, and can be applied to sports home work, practice detection in an emergency response state and other scenes.

Description

technical field [0001] The invention relates to the technical field of sit-up detection, in particular to a sit-up detection system and method based on key point recognition of human bodies and bones. Background technique [0002] At present, there are many schemes for sit-up testing, including: (1) Manual judgment method, which requires individuals to judge whether a sit-up is completed. (2) A sit-up tester with an application number of 201820875504.1, including a host and a bed body, the host is wirelessly connected to the bed body, and the bed body includes a bed board, a touch pressure sensing device, a first bracket and a second bed body Two brackets, infrared emitting device, infrared receiving device, hook plate, telescopic adjustment, touch and pressure sensing device to detect whether the shoulders touch the pad when the human body is lying down, the position of the elbows to block the infrared rays, and judge whether the subject has completed a sit-up action . (3...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the way of sit-up detection and manual judgment needs manpower, and the accuracy is low; the infrared test method, the response speed of the ordinary infrared sensor is slow, the price of the quantum type is expensive, and the required equipment is many, and the structure is complicated , It is also easy to be blocked by other parts of the body, resulting in inaccurate measurement; the photoelectric sensor method has poor environmental adaptability, and it is easy to be polluted and invalidated if it is not used in a sealed environment, and it requires a lot of machinery, which is complicated and expensive. The tester is tied to the tested It will cause discomfort to the person being tested, resulting in inaccurate measurement
