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.%针对大客车体积大、盲区多,全景环视技术在客车上的应用较少且不成熟这一现状,开展大客车的全景环视技术研究,在嵌入式平台上实现了全景环视系统.同时,为解决大客车全景环视系统对标定设备和标定场地要求复杂、标定时间长的问题,提出了一种在折反射鱼眼相机模型基础上,加入标定棋盘平面与地面的映射,采用抬高的棋盘进行计算标定的方法.实验证明,该系统全景环视效果良好、标定过程简单快速、适合推广应用.
