First sensitive chip and the second sensitive chip pass through camera serial line interface for collected infrared image and coloured silk respectively
Chromatic graph picture is sent to the arm processor in the wireless camera equipment, handles the infrared image and colour by the arm processor
Image obtains the position tracking data of the virtual implementing helmet, and the position tracking data is sent to the microcontroller
Device；The position tracking data are sent to the virtual implementing helmet by the wireless communication module by the microcontroller；
The virtual implementing helmet is used for real-time display virtual reality scenario image.
