Problems solved by technology
The general optical spatial positioning system uses laser scanning and light sensor reception to determine the spatial position of the object. This type of spatial positioning system often has the problems of relatively large measuring equipment, long measurement time and inability to measure in real time, and its application range is greatly restricted. Due to the limitations of the virtual reality space positioning, it cannot meet the requirements of short response time and high precision.

Description
technical field [0001] The invention relates to the technical field of virtual reality, in particular to a hardware circuit of a virtual reality positioning system. Background technique [0002] Virtual reality technology is a cutting-edge subject in computer information science, which integrates computer image processing, computer psychology, artificial intelligence, human-computer interaction technology, sensor technology, network and other information disciplines. Existing virtual reality spatial positioning generally uses optical or ultrasonic modes for positioning and measurement, and the spatial position of the object to be measured is derived by establishing a model. The general optical spatial positioning system uses laser scanning and light sensor reception to determine the spatial position of the object. This type of spatial positioning system often has the problems of relatively large measuring equipment, long measurement time and inability to measure in real time...
