The invention relates to a traffic detection method and device based on unmanned aerial vehicle vision and millimeter wave radar. The method is used for traffic information detection of a target road section, and the target road section comprises continuous first/second target road sections. The method comprises the following steps of: detecting the number of target vehicles in the first target road section and the speed of each target vehicle in a historical time period by using a millimeter wave radar, and obtaining a relation curve of standard traffic flow density and standard vehicle flow velocity; acquiring target vehicle information of the first target road section at the current moment by using the millimeter wave radar and an unmanned aerial vehicle respectively, and judging whether the information acquired by the millimeter wave radar is matched with that acquired by the unmanned aerial vehicle; if yes, obtaining the traffic flow density and the traffic flow velocity of the first target road section by using the target vehicle information at the current moment acquired by the millimeter wave radar; and calculating the traffic flow density and the traffic flow velocity of the second target road section by using the target vehicle information of the second target road section at the current moment acquired by the unmanned aerial vehicle and the relation curve. Accurate detection of traffic information data is realized.

    本发明涉及一种基于无人机视觉和毫米波雷达的交通检测方法及装置。该方法用于目标路段的交通信息检测,目标路段包括连续的第一/第二目标路段,方法包括:利用毫米波雷达检测历史时段内第一目标路段的目标车辆数量以及每辆目标车辆的速度,得到标准车流密度与标准车流速的关系曲线;分别利用毫米波雷达和无人机采集当前时刻第一目标路段的目标车辆信息,判断两者是否匹配;若匹配,则利用毫米波雷达采集的当前时刻的目标车辆信息得到第一目标路段的车流密度以及车流速;利用无人机采集的当前时刻第二目标路段的目标车辆信息,结合关系曲线,计算得到第二目标路段的车流密度以及车流速。实现了交通信息数据的精确性检测。
