The invention discloses a data compensation method and device for fusion between roadside radars. The method comprises the following steps: acquiring detection point information of radar layout; detecting a target object by using the detection point information, and determining the motion direction of the target object; and calculating an adaptive coefficient according to the occurrence time of the target object and the motion direction so as to determine a detection error. According to the invention, after the weighted relocation algorithm is adopted for the same target detected by different radars, the distance between two detection points in the physical space is closer, and the fusion precision is higher; after the weighting coefficient algorithm related to time is adopted, the target is determined more accurately, and mismatching is less. The interference caused by the newly appearing false target is avoided; after the compensation algorithm is adopted, the fusion algorithm becomes simple, and the fusion position becomes more accurate. And when the target positions detected by different sensors are different, a filtering algorithm is omitted.

    本发明公开一种路侧雷达间融合的数据补偿方法及装置,方法包括:获取雷达布设的检测点信息;利用所述检测点信息对目标物体进行检测,确定所述目标物体的运动方向;根据所述目标物体的出现时间以及所述运动方向计算自适应系数,以确定检测误差。本发明对不同雷达检出的同一目标采用加权重定位算法后,在物理空间上两个检测点的距离更近,融合时精度更高;采用与时间相关的加权系数算法后,在目标确定时更准确误匹配更少。避免了刚出现的虚假目标造成的干扰;采用补偿算法后,融合算法会变得简单,融合位置也变得更精确。在不同传感器检出的目标位置不同时,省去了滤波算法。
