Construction And Improvement Of Three-dimensional Display System Based On Shutter Glassess

This paper introduces frame sequence stereoscopic display technology and how the driveworks based on further research about the NVIDIA three-dimensional products. Analysis of theworking principle of3D video and corresponding synchronous signal processing programmingframework is mentioned. RF synchronization used in the shutter glasses stereoscopic displaysystem, has more advantages than the infrared, which solves the limitations of space infraredsynchronization.When unable to obtain the synchronous signal directly, an alternative approach is to use avertical synchronization signal and infrared pulse. Vsync extraction circuit based on DVIinterface,it extract a single sync pulse out of the DVI blue signal and solve the problem of timesynchronization. High-speed infrared diode used for receiving infrared pulse, Synchronizationinformation hidden in the infrared pulse.After both are available, a real-time analysis programhelp to identify the current picture belongs to the left eye or right eye. Of course, the premise isthe infrared protocol is known.The system adopts nRF24L01wireless RF chip to transmit synchronous signal.Radiocommunication is easy to receive the same frequency interference, therefore the use of frequencyhopping technology means to improve the RF communication anti-jamming and reliability ofdata.Auto-answer and automatic retransmission makes the delay calculation very complex,dynamic correction algorithm improves the fault tolerance of delay calculation. The actual testresults prove that the glasses work well.
