基于鱼眼镜头的全景辅助驾驶系统研究

Research on Panorama Assistant Driving System Based on Fish Eye Lens

根据全景辅助驾驶系统的要求,设计了一种非球面鱼眼镜头,确定了鱼眼镜头的设计参数和光学材料,构建了鱼眼镜头的初始结构,通过对鱼眼镜头的像差校正及优化设计,给出了鱼眼镜头的设计结果。将设计的非球面鱼眼镜头、畸变校正算法和整体硬件进行实现与验证,集成到车辆辅助驾驶全景显示系统中,通过对多个镜头采集的图像进行合成并进行了实际应用验证。结果表明,系统应用良好。

According to the requirements of panorama assistance driving systems, a non-spherical fish eye lens is designed. The design parameters and optical materials of the lens are determined, and the initial structure of the lens is built. Through the aberration correction and optimization design of the lens, the design results are given. The designed non-spherical fish eye lens, distortion correction algorithm and overall hardware are implemented and veri- fied to integrated with the panoramic display driver assistance system. The images captured by multiple lenses are synthesized and applied, and the experimental results show that the system has good application.
