This product adds three sets of infrared camera modules with infrared fill lights, referring to the design of a 15.6-inch 3D display tablet. The camera module components are combined with the spatial positioning algorithm software, which can track and locate the target in the stereo space in real-time, obtain the 6DoF data of the target, map the data to the 3D object in the virtual space, and realize the interaction with 3D objects in the virtual space.
