Motive Action Capture：How to Achieve Accurate Motion Capture

1. Introduction

Action capture technology, as a new emerging technology, has been widely used in game, animation, virtual reality and other fields. Action capture technology has been widely used in the entertainment industry, and its application in the medical and sports fields has also made significant progress. In the process of action capture, how to capture the underlying motive of action and achieve accurate motion capture has always been a difficult problem. In this paper, we will introduce the basic principle of action capture technology, analyze the basic steps to achieve accurate motion capture, and introduce the main methods and technologies used in action capture technology.

2. The Principle of Action Capture

Action capture technology is to capture the motion data of human body through special equipment and then display these motion data in three-dimensional space. The equipment used for motion capture is generally divided into two categories, hardware and software. The hardware includes camera hardware, motion capture hardware and other accessories. The software includes motion capture software and other related software.

In the process of action capture, the camera hardware is used to capture the motion of human body, and the motion capture hardware is used to collect the data of the motion. The data collected by the motion capture hardware includes the position of each joint of the human body, the force applied to each joint, the direction of the human body and other related information. The motion capture software is used to analyze the data collected by the motion capture hardware and convert it into three-dimensional motion data.

3. Steps to Achieve Accurate Motion Capture

In order to achieve accurate motion capture, it is necessary to complete the following steps:

(1) Set up the motion capture system. The motion capture system should be set up correctly according to the requirements of the application scenarios. It is necessary to select the appropriate motion capture equipment, configure the motion capture software, and set up the motion capture environment.

(2) Calibrate the motion capture system. It is necessary to adjust the position of the motion capture equipment and the motion capture environment, so that the motion capture system can accurately capture the motion data.

(3) Capture the motion data. It is necessary to capture the motion data of the human body accurately, and analyze the motion data to obtain the basic parameters of the motion.

(4) Process the motion data. It is necessary to process the motion data to obtain the desired motion data. The motion data can be processed through the motion capture software or other related software.

(5) Generate the motion data. After processing the motion data, the desired motion data can be generated and used in the application scenarios.

4. Methods and Techniques Used in Action Capture

At present, the methods and techniques used in action capture mainly include optical motion capture, magnetic motion capture and inertial motion capture.

Optical motion capture is a motion capture technology based on the principle of optical triangulation. It uses multiple cameras to capture the motion of human body, and then uses motion capture software to analyze the motion data and generate the motion data. Optical motion capture technology is widely used in game and animation production.

Magnetic motion capture is a motion capture technology based on magnetic field. It uses magnetic sensors to capture the motion of human body, and then uses motion capture software to analyze the motion data and generate the motion data. Magnetic motion capture technology is mainly used in medical applications.

Inertial motion capture is a motion capture technology based on inertial measurement unit. It uses inertial sensors to capture the motion of human body, and then uses motion capture software to analyze the motion data and generate the motion data. Inertial motion capture technology is mainly used in sports applications.
