- Abstract
Orthoses are aids that compensate for the loss of function of a particular part of the locomotor system, while prostheses are devices that compensate for the loss of a part of the body. Digital technologies have enabled the measurement and the production of such aids. The production technology is a CNC or robotics arm-based system comprising several modules that are relatively positioned with a submillimetre precision. In practice, the implementation and calibration of such systems are challenging, especially in cases of adapting already used hardware or when the control unit is undocumented or closed to outside interventions. Our approach responds to several challenges, resulting in a unique visual solution for fast and affordable calibration. This approach enables reading the machine positions from an external computer without a physical connection to the control unit, tracking the movement of the machine in near real-time, and finally calculating calibration parameters of the observed system.
