This work is a binocular stereo vision system based on the ATLYS FPGA development platform and VmodCAM binocular camera module. VmodCAM is used to collect two-way visual information. The FPGA development platform is responsible for the processing of visual information and high-speed analysis of images. The acquired two-way image information can be obtained by analyzing and processing, and the depth information on the two-dimensional image can be obtained. The embodiment of depth information is designed in this work. One of them is the stereoscopic display of visual information, which is processed to generate superimposed red and blue 3D images, giving people an intuitive three-dimensional experience. The design aspect can be applied to the collection and display of stereo vision, and the positioning is a stereoscopic vision acquisition and display system. On the other hand, through the high-speed image processing system designed on the FPGA chip, the depth information of the image, that is, the three-dimensional coordinates of the object relative to the binocular camera in the environment, can be calculated according to the difference between the left and right images. This design aspect can be applied to the field of human-computer interaction and machine vision as a cognitive device for machine-to-environment situations.
The FPGA development board plays a major role in this work: 1 configuring the camera module, collecting camera data; 2 buffering the image data in the off-chip DDR2; 3 completing the image analysis processing; 4 completing the image display and UART data transmission.
Design goalsOn the one hand, the design of the stereoscopic real-time acquisition and display system is completed, and the stereoscopic picture can be seen in real time after wearing 3D glasses; on the other hand, the three-dimensional positioning of the object is realized.
Realized: real-time acquisition and display of stereo vision based on red and blue 3D glasses; three-dimensional spatial positioning of infrared spots.
It will realize: stereoscopic real-time acquisition and display based on polarized 3D glasses; object space localization and environment three-dimensional reconstruction in a simple environment, and developed into a device for human-computer interaction.
Design overviewThis design is a video, image acquisition and processing system completed on the FPGA chip, and completes the reconstruction and mathematical modeling of the three-dimensional image. The system-on-chip is jointly developed using VHDL+Verilog and has a high data processing speed. The two aspects of the design have been initially realized, and the image acquisition and processing processes are all completed by the on-chip system, which lays a good foundation for the further optimization of the design.
