High-definition video-based multi-channel top-view vehicle surrounding monitoring system for mobile navigation devices

Providing visual information around automobile can make drivers blind-spot-free, which is helpful for several occasions such as parking, lane change and backward movement. In this paper, the vehicle surrounding monitoring system with multiple channel high-definition (HD) videos, which is embedded in portable navigation devices, is presented. The system collects three channel video inputs from rear, left, and right side of the vehicle, transforms each inputs into top-view image, respectively. Finally, the transformed outputs are aligned, and then displayed on the screen for assisting the driver. Implementation and its results showed that the system provides HD vehicle surrounding monitoring video which is helpful especially in parking assistance.
