Virtual interactive motion auxiliary system and method based on inertial motion capture equipment

Abstract

The invention relates to a virtual interactive motion auxiliary system based on inertial motion capture equipment, and the system comprises a motion capture module which is used for constructing a 3D character model, collecting human body motion data, and transmitting the human body motion data to a human-computer interaction module; a heart rate measuring module which is used for collecting and processing heart rate data of a human body; a body fat measuring module which is used for collecting body fat data of a human body and processing the body fat data; and a man-machine interaction module which is a user interface integrating basic information acquisition, data analysis and monitoring, image display, a voice broadcast part and mode selection, adopts a Unity 3D platform, and is displayed on a display screen in a client form. The invention further discloses an auxiliary method of the virtual interactive motion auxiliary system based on the inertial motion capture equipment. The method is suitable for common people, is not limited to a certain type of people, and can be popularized to the public; The system has multiple functions, can reproduce motion actions in a virtual world, and also can carry out action error correction, body fat analysis, heart rate real-time monitoring and alarm.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction for fitness sports, in particular to a virtual interactive motion assistance system and method based on inertial motion capture equipment. Background technique [0002] Health problems are a common concern of the society. Although there are a variety of exercise methods to choose from, there are still problems that cannot be underestimated during the exercise process. For example, irregular movements can easily lead to muscle and joint damage. The effect of exercise becomes worse and the efficiency becomes lower; irregular exercise and excessive exercise intensity will increase the burden on the body, and even pose a serious threat to personal life. In addition, different groups of people have different exercise needs, especially the heart pumping function and lung ventilation capacity of middle-aged and elderly people are declining year by year, and osteoporosis increases the r...

Problems solved by technology

[0005] The deficiencies of the various motion assistance systems that have been developed so far that use optical motion capture or inertial motion capture equipment to capture 3D poses are: First, the applicable population is single: most of the motion assistance systems are only suitable for special groups of people, such as Patients undergoing rehabilitation training or certain types of professional athletes have not popularized it to the public; second, the exercise mode is single: the system only supports rehabilitation treatment or professional sports training, such as table tennis training; third, Single structure and function: the system can only collect and process motion data through motion capture, without the development of other modules, and lacks versatility; fourth, it is inconvenient to use: most of the sports assistance devices on the market are optical motion capture devices, However, it is bulky, expensive, and affected by factors such as site conditions, so it is not convenient for users to use it anytime and anywhere; fifth, safety is not emphasized: the system mainly focuses on detecting whether the sports training is up to standard, but for real-time monitoring of sports safety , did not play a preventive role against possible dangers
