Then, high-resolution cameras are strategically positioned to track those reflectors during the actor’s movement. Each camera generates the 2D coordinates for each reflector, obtained via a segmentation step. Proprietary software is then used to analyze the data captured by all of the cameras to compute the 3D coordinates of the reflectors. These systems are the most expensive ones in the market due to their cutting-end technological nature, such as the high-resolution cameras and sophisticated proprietary software. The values can hit the USD 250,000 bar. The advantages of using these systems are mainly the very high sampling rate, which enables the capture of fast movements such as martial arts, acrobatics and gymnastics, among others. The sampling rate usually depends on the cameras used, meaning that the higher the resolution, the higher the sampling rate will be. Sampling rates of up to 200 frames/second are achievable. Another advantage is the freedom offered by these systems, since, unlike the other systems, there are no cables or limited workspace and the reflectors pose no restrain or cumbersome effect on the actor. Also, since the reflectors offer
