The optical tracking system is a high-precision solution that can be used to accurately track the position and movement of the human body in the virtual reality environment, compared with the inertial motion capture system that relies on gyroscopes and magnetometers to track human movements using sensors, the data collected by the optical tracking system will be more accurate, and it is very suitable for strong magnetic environments (for example, in the C**E system, strong magnetic interference often occurs in the field, which eventually leads to drift and inaccuracy of tracking).
The ART optical motion capture system is mainly composed of three parts: ART infrared tracking camera, ART optical tracking marker and ART controller. Its working principle can be simply understood as the infrared camera transmits data such as position and human movement to the art controller by receiving the light reflected by the reflective marked points, and analyzes it, and finally calculates it through a series of algorithms. Determine the real-time location of people in virtual and real spaces.

Precise positioning in the virtual space is very important, as it will determine whether the visual image that the user can see is clear and in a 3D display environment, and without a precise positioning system, the image that the user sees will not have a 3D effect. (The active polarization 3D glasses will provide a 3D effect according to the user's position, and when equipped with the ART optical tracking system, the glasses will adjust the 3D image display direction according to the user's real-time position, so that the user will always face the 3D picture frontally, so as to achieve a 3D stereoscopic display effect.) ）
The ART optical tracking system has a variety of tracking cameras to choose from, and different cameras can be adapted to various environments. For example, the Art Track6 M, due to its compact size of the camera in its class, is ideal for placing in environments where capture space is limited. The more popular ART Track5 infrared tracking camera is often widely purchased as the main tracking equipment in the tracking matrix because it is compatible with a variety of systems and is lower.
Art Track5 Tracking Matrix.
The ART optical tracking system can not only accurately track the target, but also have the advantages of low latency and high resolution. With a refresh rate of up to 120Hz, a sensor resolution of 1152 x 984, and a high-performance infrared LED of 850nm, the Art Track5 can be configured with up to 8 devices in one Art Controller at the same time. The ART Track6 M features a refresh rate of up to 500Hz, a 1280 x 1024 sensor resolution, an 850nm high-performance IR LED, and an ultra-small 30mm diameter and 101mm length.

ART Reflective Tracing Marker.
The ART optical tracking system can be widely adapted to a variety of C**E, POWERWALL, LED display systems, and can achieve 360-degree all-round tracking without dead angles by attaching the tracking target reflective points to all parts of the body. Due to the absence of magnetic interference in the optical system, tracking will not drift in some spaces with cabinets or sound systems, and since there is no need to recalibrate the equipment during tracking, the ART optical tracking system is also more convenient and faster to use.
