摘要：

Based on the present status of buses, such as large volume, a number of blind spots, less application and immaturity of top-view technology, in the thesis, the research on the top-view technology applied in buses was carried out. A top-view system based on embedded platform was established. A calibration calculation method was proposed, due to the lack of complex calibration equipment, large calibration work site and long calibration time constraints. After studying the catadioptric fisheye camera model, it was revealed that it was greatly necessary to add a mapping of calibration board plane and ground, using the raised calibration board plane for calibration calculation. The experiment results indicate that the system provided an effective good top-view and allowed for a simple and fast calibration process, and thus, suitable for application.
