为了实现车载摄像头的超广角成像，解决倒车影像系统不能全面照顾周围视角的问题，设计了一款超广角车载摄像头。对该摄像头所采用的图像传感器、超广角成像技术、硬件电路设计及接口EMC防护的应用进行研究。根据当前车厂对摄像头的要求选择了基于美国Omnivision公司的CMOS图像传感器OV7962作为成像芯片。采用一种新的凝视型视场全景成像技术——鱼眼透镜成像，并通过匹配成像芯片的参数计算出镜头的焦距和分辨率。对摄像头硬件电路的设计及接口电磁兼容性(EMC)防护进行测试和改进。实验结果表明: 摄像头可实现210°超广角成像，接口EMC防护已通过ISO-7637-2 脉冲5b标准测试。满足了对倒车影像系统全面顾及周围视角的要求，另外该车载全景摄像头还具有成本低、性能稳定、分辨率高、夜视效果好等优势。

In order to realize ultra-wide-angle image for automotive camera, an ultra-wide-angle automotive camera is designed to solve comprehensive monitoring perspective issue in reversing image system.Its applied such as image sensor and ultra-wide-angle imaging technique, hardware circuit design and the EMC protection of interface are investigated. We opted for a Omnivision-based CMOS image sensors OV7962 according to the current auto companies’ requirements. The lens adoptes the new staring panoramic imaging technology —fish-eye lens imaging and calculating the focal length and resolution of the lens by matching the parameters of image chip. The hardware circuit design and EMC protection of the camera are tested and improved.Experimental results indicate that the camera can achieve 210° ultra-wide-angle image and the EMC protection of interface has passed the ISO-7637-2 pulse 5b testing standard.It can satisfy the comprehensive monitoring around perspective requirements of reversing image system.In addition, this automotive panoramic camera also has the advantages of low cost, stable performance, high resolution, as well as super night vision.
