Embodiment Construction

[0035] refer to Figure 1-9 . The present invention is based on the Kinect-based non-contact type student's physique evaluation method concrete steps as follows:

[0036] According to the different test items of standing long jump, sit-ups, pull-ups, sitting forward bend, and height, the standard physical measurement room is divided into several independent test rooms, namely Room1, Room2, Room3, Room4, and Room5. Install a Kinect somatosensory recognition device, an RFID card reader and a handheld terminal at a fixed location. When the measured object enters the physical measurement room, the identity of the measured object is identified and compared through the one-card that is carried with him.

[0037] The physical measurement equipment in all test rooms is managed and initialized by the equipment monitoring platform, and the terminals in each room can be viewed remotely and some parameters modified. After the identity verification of the tested object, a series of stan...

Abstract

The invention discloses a Kinect-based non-contact student physique evaluation method, which is used to solve the technical problem of poor practicability of the existing Kinect-based human behavior detection method. The technical solution is to obtain the human body posture through the color and infrared cameras equipped with Kinect, and display it on the interface in real time. Use the inferred skeletal nodes to record the position of each joint of the human body, and compare the position changes of each joint node when the human body performs various sports to infer human behavior, and match with the preset standard data to detect whether the human body's movements are standard , and finally feed back the result to the interface. Compared with the background technology method, it gets rid of the shackles of adding additional equipment on the human body to be tested, and is convenient for centralized testing of a large number of physical measurement objects; the background database system automatically obtains physical fitness monitoring data, which is convenient for analyzing and managing students' physical conditions; The errors are all less than 2%, and are not easily affected by human subjective factors.

Description

technical field [0001] The invention belongs to the technical field of human-computer interaction, and in particular relates to a Kinect-based non-contact student physique evaluation method. Background technique [0002] Physique is the material basis of human life activities and labor and work ability. The determination of physical fitness can lay a foundation for our country's national physical fitness monitoring system to grasp the laws of the development and change of adult physical fitness. Traditional physical fitness assessment basically uses manual testing and recording, which is slow, heavy workload and error-prone. For some important motion parameters in students' physical training, such as joint angles, it is difficult to measure by traditional methods, and it cannot provide the conditions for non-contact machine measurement, and human factors interfere greatly. [0003] The document "Chinese Invention Patent Application Publication No. CN105046281A" discloses a...
