Qualisys (Sweden)
About: Qualisys provide tools for precisely measuring equine movements using sequence coded active markers. Their objective lameness gait analysis system QHorse has clinical and research uses.  For Horse lameness gait analysis the horse is equipped with markers on the head, withers and pelvis, which are detected by twenty cameras in the riding arena. On the straight line, as well as on the circle, the horse can be evaluated. Results are directly analysed and seen on the screen in the arena.  Optical motion capture provides accurate 3D-positions of the different limbs and body parts and thus enables the creation of biomechanical models describing the animals’ movement apparatus. The motion capture technology is very non-intrusive, only light-weight small markers needs to be attached to the animal and will not disturb the normal movement pattern in the measurement situation. When measuring the distal limb of a horse, the movement frequency content is substantially higher than from a human requiring higher frame rates from the cameras. By using the high speed-mode of the Qualisys cameras you can capture in frequencies higher than 1,000 frames per second.    Video.
