The invention relates to the technical field of roadside sensing, in particular to a roadside sensing control system and method based on Leiyu fusion. Comprising a sensor unit, a data processing unit and an early warning control unit, according to the method, more comprehensive and accurate perception of traffic participants is realized by integrating laser radar data and video data, and meanwhile, a conversion relation between a laser radar coordinate system and a visual coordinate system is determined based on space matching of a calibration object, so that the same target detected by different sensors can be accurately corresponding in space, and the accuracy of target detection is improved. The accuracy of judging the traffic condition by the whole roadside sensing system is greatly improved, and in addition, when the control threshold value is compared with the pre-stored control threshold value, whether early warning is sent out or not can be judged more scientifically and reasonably.
本发明涉及路侧感知技术领域,具体为基于雷视融合的路侧感知控制系统及方法;包括传感器单元、数据处理单元和预警控制单元;本发明通过综合激光雷达数据和视频数据,实现了对交通参与者更全面且精准的感知,同时,基于标定物的空间匹配,确定激光雷达坐标系与视觉坐标系之间的转换关系,使得不同传感器探测到的同一目标能在空间上准确对应起来,极大提高了整个路侧感知系统对交通状况判断的准确性,此外,当与预存储的控制阈值进行对比时,能更科学、合理地判断是否发出预警。
