High-speed industrial cameras are used in three-dimensional tracking of human motion to accurately reproduce the movements and trajectories of athletes, and to output movement data such as displacement, velocity, angular velocity, etc., at any point in time for athletes, facilitating quantitative analysis, combining human physiology and physics. Principles, research and improvement methods, to make the movement observation of human body get rid of purely relying on experience, enter the era of theorizing and digitization.
The three-dimensional tracking of human motion based on photoelectric measurement is non-contact measurement, which has the advantages of no extra load on the human body, no interference with limb movements, and the closest to the actual working conditions. The detection and processing of human motion information is based on human motion. Accurately measure and analyze the displacement, velocity, acceleration, interaction forces, and myoelectric signals of various parts of the human body during exercise, and process and analyze them.
(1) Sports training is currently in the transitional stage from experience to science, and the understanding of human movement is also moving from being roughly to a precise one. How to obtain accurate, timely, and multi-faceted exercise parameters and use these parameters is important for improving athlete performance. means;
(2) In the field of rehabilitation, in order to evaluate disability, diagnose diseases, and identify the effects of rehabilitation devices, an objective and effective method is to perform gait and other functional assessments of human body in the three-dimensional simulation and analysis system of human motion;
Figure 1 shows a sports rehabilitation simulation experiment. In this project, a binocular stereo vision system consisting of a high-speed industrial camera was used to capture and track the three-dimensional coordinates of multiple landmarks on the measured person. The binocular stereo vision system analyzes the three-dimensional coordinates of these landmarks, calculates multiple joint displacements, accelerations, and postures, and combines related sensors to obtain muscle, joint stress, and myoelectric information, and objectively and effectively perform various parts of the human body. Functional assessment.
(4) In the analysis of labor protection and traffic accidents, in order to rationally design protection devices and protection systems, it is necessary to understand the mechanics of injury and the ability of human tissues and organs to withstand impact and acceleration. In addition, in the fields of ergonomics research, simulation training, and human animation production, there are many possibilities for the three-dimensional simulation and analysis of human motion.
The above description shows that there are many levels of application of the high-speed camera system in the three-dimensional tracking of human motion. It can be expected that with the development of the technology itself and the improvement of the technical level of the related application fields, the research will be applied more and more widely. If you are also interested, you are welcome to call Vivitek and we will discuss and discuss together.
