Solutions for equine and canine locomotion
From the research perspective it is important to understand the actual biomechanics of the different types of animals in order to be able to address the previous questions. A specific application is objective horse lameness assessment/detection. When it comes to smaller animals such as dogs the main focus is research and to build knowledge on how the dogs movement apparatus actually works. A specific application related to dogs is to measure load and stress on the neck of law enforcement/military dogs attacking humans (that are protected during the test).
Large volumes & Outdoor motion capture
In the case of measuring on horses, large measurement volumes can be needed depending on the situation. Qualisys wand calibration technique can be used to create large accurate measurement volumes. Typically, outdoor measurements are also requested and can be performed using Qualisys cameras’ active filtering feature. 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.
Advantages of mocap
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.
