Abstract: The around view parking system uses 4 wide angle cameras installed in the car’s front, back, left and right to collect the images in real time, which are transmitted to the image processing equipment for correction, projection transformation and image composition on the screen to form a 360 degree panoramic view. The system uses processor HI3520D and video decoder NVP1918C as the core of hardware, and uses the fish-eye correction algorithm, projection transformation and reverse projection algorithm as the software core. The experimental results show that the around view parking system can achieve seamless and clear images in real-time display.

摘要： 全景泊车系统利用安装在车身前后左右的4个广角摄像头实时采集周围的图像，并传送给图像处理设备进行校正、俯视变换和图像合成，最后在显示屏上形成一幅360°的全景俯视图。系统以处理器HI3520D和视频解码器NVP1918C为硬件核心，以鱼眼校正、投影变换和逆向投影算法为软件核心，最终实现实时显示无缝和清晰画面的360°全景泊车影像系统。
