We have developed a low-cost 3D- motion analysis system for gait analysis. We used two camcorders to capture the images of the moving subject. The images were transferred to the computer using a video grabber card. The speed of the transfer was limited by the camcorders speed that was 25 fps. The user- friendly software developed in this project detects the passive markers images that were placed on the subject and gives the trajectory of each marker. We obtained the position data file for each marker by using a calibration set-up. This data file is used for further biomechanics analysis for different researches.
