Opticallytracked

Optically tracked refers to a method of motion capture that utilizes optical markers and cameras to record and analyze the movement of objects or individuals. This technology is widely used in various fields, including virtual reality, animation, sports science, and medical rehabilitation. The fundamental principle involves attaching reflective or active markers to the subject. These markers are then illuminated by infrared light, and a series of cameras strategically positioned around the capture volume detect the reflections from these markers.

By triangulating the position of the markers from multiple camera viewpoints, the system can accurately reconstruct their three-dimensional coordinates in real-time or from recorded footage. This data can then be used to create digital representations of movement, allowing for the animation of virtual characters, the analysis of biomechanics, or the interaction with virtual environments. The accuracy and quality of optical tracking systems can vary depending on the number and resolution of the cameras, the type of markers used, and the complexity of the capture environment. Some advanced systems can track hundreds of markers simultaneously with high precision, while simpler setups might be suitable for less demanding applications. The processing of the captured data is crucial for translating the raw marker positions into meaningful motion data.
