Design And Implementation Of Steroscopic Display System Based On FPGA

After decades of development, stereoscopic display has become widely used in the fields of video surveillance, industrial control, scientific research, commercial and consumer applications. The stereoscopic display technology includes 5 fields of technologies, which are capture, temporary storage, conversion, transmission and display. With the continuous improvement of microelectronics technology and electronic design capability, there are more and more applications of high-performance image sensor. On the other hand, with the continuous enhancement of people’s requirement of the display quality, the display resolution and frame rate is becoming higher and higher. The improvement of front-end video capture and back-end means the enhancement of data amount, the increasement of transmission time and the upgrade of costs. Therefore, there’s practical significance in the design of real-time, cost-effective three-dimensional display system with a large amount of data.In this thesis, the basic knowledge and techniques stereoscopic display device are introduce and stereo microscope system and stereoscopic display system without auxiliary are put forward according to users’ actual needs. In stereo microscope system, the parallax images collected from two input channels of CMOS image sensor are sent to 3D display through DVI interface after image cache and format conversion, compatible with LCD switch glasses to gain stereoscopic perception.Stereoscopic display system without auxiliary has two parts, which were active optical engine and video interface. The active optical engine part could achieve addressable backlighting by tracking the position of pupils. Lighting control achieved by extracting the timing of the liquid crystal panel synchronizing signal. The video interface part used 3G-SDI interface to capture surveillance camera’s images, converted the format through cache, then sent to the monitor via HDMI.Both of the two systems in this thesis undergo device selection, hardware design, software design and overall debugging. After the actual application, both systems can meet the actual performance requirement with high cost performance ratio, strong system expandability and strong practical value.
