Study Of The Panoramic Image Acquisition,processing And Display Technology Based On FPGA

Due to the large body of some closed special vehicles and large trucks,there is a large blind area in the field of vision,which makes it difficult for drivers to get the road conditions around the vehicles in real time.In order to solve these problems,a panoramic image acquisition and display system is designed,which can observe the surrounding area of vehicle body in real time with the rotation of the head.Considering the actual demand and environment of driving special vehicles,this paper designs the module of FPGA-based fixed multi-camera panoramic image acquisition and display,and realizes multi-camera panoramic image acquisition,image buffering,head attitude data receiving and processing,and image panorama display.In order to obtain the similar experience with the naked eye,a scheme of image follow-on display is designed,in which only the image corresponding to the corner of the driver’s head is selected.Therefore,a head attitude sensor module based on STM32 is designed,which realizes the configuration of six-axis sensor and the reading of attitude data through I2 C communication,and the real-time calculation of the above attitude data.The experimental results show that the error between the detection angle and the actual rotation angle is less than 1°,and the image shows no drag and distortion,which can effectively eliminate the blind area of the driver’s field of vision and reduce the driving difficulty.
