Theia3D is a markerless motion capture system developed for biomechanics research. It extracts the human body from video data captured by more than six cameras and automatically generates skeletal model data using rigid body tracking and inverse kinematics. There is no need for markers or specialized suits that were essential in traditional motion capture systems. You can wear regular clothing, and preparation time is minimal. Additionally, no specialized knowledge is required to operate the software, allowing anyone to easily perform human measurements. 【Features】 ■ Analyzable from video data captured by synchronized cameras (more than six). No specialized cameras required. ■ Supports analysis of only the upper body or lower body. ■ No limit on the number of people that can be analyzed. ■ Supports motion analysis software Visual3D. ■ Batch data processing functionality available.

This document introduces motion capture using AI technology and its applications.

Using the "MAC3D System," three-dimensional data of walking movements is obtained on a walking path equipped with a floor reaction force measurement device. By using analysis software on the acquired data, inverse kinematics and inverse dynamics analyses can be performed, allowing for the calculation of difficult-to-measure data such as center of mass position and joint torque. The analysis results can be displayed in graphs within the analysis software and can also be output as Excel data. 【Features】 ■ Acquired data: Marker three-dimensional positions, floor reaction forces, electromyography, trigger signals, AVI video ■ Marker set: Helen Hayes, etc. ■ Mass model: Zatsiorsky, custom ■ Skeleton engine: Skeleton Builder, Calcium, hybrid model ■ Analysis methods: Inverse kinematics analysis, inverse dynamics analysis *For more details, please refer to the related links or feel free to contact us.

The "MAC3D System," an optical reflective motion capture system, is an ideal solution for three-dimensional measurement (data collection) of body movements. It excels in real-time capabilities, allowing for immediate verification of the system's status and the subject's movements during measurement, enabling quick assessment of whether the desired data has been obtained. Data analysis can be performed using dedicated software, allowing for inverse kinematics and inverse dynamics analysis to evaluate the stability and maturity of movements, and appropriate prescriptions can be made for each individual based on the results. 【Features】 ■ Acquisition of three-dimensional data of walking movements ■ Subjects only need to have reflective markers attached ■ Capable of calculating difficult-to-measure data such as center of gravity position and joint torque ■ Analysis results: displayed in graphs within the analysis software and output as Excel data ■ Immediate assessment of whether the desired data has been obtained *For more details, please refer to the related links or feel free to contact us.

The motion capture system "MAC3D System" can acquire three-dimensional position data of markers attached to the body. Using point data, it estimates body data such as joint positions, joint angles, center of gravity, and muscle strength through musculoskeletal model motion analysis software. There are ongoing efforts by various automobile manufacturers and research institutions to explore whether this body data can be used as one of the indicators for evaluating ride comfort in vehicles. 【Features of MAC3D System】 ■ Capable of acquiring three-dimensional position data of markers attached to the body ■ Estimates body data such as joint positions, joint angles, center of gravity, and muscle strength using musculoskeletal model motion analysis software from point data *For more details, please refer to the related links or feel free to contact us.
