Region-of-interest determination method and device

The embodiment of the invention discloses a method and a device for determining a region of interest, which can screen out the region of interest of a vehicle according to the connection relationship among the road sections and the distance between the boundary point of each road section and the vehicle after the current target road section of the vehicle is positioned, that is to say, the region of interest of the vehicle can be determined in all road sections in a sensing range. According to the method, a part of road sections are screened out to serve as the region of interest, so that only the perception information of the region of interest can be calculated during environment perception, and compared with calculation of all the perception information, the calculation complexity can be reduced, namely, the environment perception difficulty can be reduced, and the accuracy of an environment perception result can be improved. 本发明实施例公开一种感兴趣区域确定方法及装置，能够在定位车辆当前所在的目标路段后，根据各路段之间的连接关系，以及各路段的边界点与车辆之间的距离，筛选出车辆的感兴趣
