The invention belongs to the technical field of vehicle positioning systems, and particularly relates to a vehicle-mounted all-round looking system with a UWB (Ultra Wideband) technology, which comprises the following steps that an all-round looking camera mounted on a vehicle continuously emits UWB signals and communicates with a smart phone of a vehicle owner, and a 360-degree all-round looking controller system determines whether the vehicle owner receives the signals according to the time when the vehicle emits the signals and the time when the vehicle owner receives the signals; calculating the time difference between the vehicle owner and the vehicle owner, obtaining the relative position between the vehicle and the vehicle owner by using a TDOA positioning algorithm, displaying the position relationship between the vehicle owner and the vehicle on the mobile phone terminal of the vehicle owner, and then searching the vehicle by the vehicle owner through the position relationship; the vehicle is provided with the 360-degree looking-around controller system used for carrying out information communication with a mobile phone of a vehicle owner, through the 360-degree looking-around controller system carried by the vehicle, the UWB-TDOA positioning algorithm and the UWB wireless communication technology, signal communication between the vehicle and the vehicle owner can be achieved, and the vehicle owner can conveniently and rapidly find the vehicle.
本发明属于车辆定位系统技术领域,具体的说是一种带UWB技术的车载环视系统,包括以下步骤:车辆上安装的环视摄像头不断地发射出UWB信号,和车主智能手机进行通信,360环视控制器系统通过车辆发出信号的时间与车主接收到信号的时间,计算二者所产生的时间差值,利用TDOA定位算法进而得到车辆与车主之间的相对位置,并且将车主与车辆之间的位置关系在车主手机端进行显示,然后车主可以通过位置关系进行车辆的寻找;车辆搭载有360环视控制器系统用于和车主手机进行信息交流,本发明通过车辆搭载的360环视控制器系统以及UWB‑TDOA定位算法和超宽带无线通信技术(UWB),可以使得车辆与车主之间进行信号的交流,方便车主快速的寻找车辆。
