The invention is suitable for the technical field of traffic information collection, and provides a traffic operation information detection method and device based on video data, and terminal equipment, wherein the method comprises the steps: determining a centroid coordinate of each vehicle in each frame of video image; obtaining a detection distance according to a first preset virtual line and asecond preset virtual line; according to the centroid coordinate of each vehicle in each frame of video image, the first preset virtual line, the second preset virtual line and a timestamp corresponding to each frame of video image, obtaining a first vehicle number and a first travel time sum of all vehicles passing through the first preset virtual line and the second preset virtual line in the video image sequence; and calculating an average vehicle speed corresponding to the video image sequence according to the detection distance, the first vehicle number and the first travel time sum, andtaking the average vehicle speed as first traffic operation information corresponding to the video image sequence. According to the invention, misjudgment during information statistics can be avoided, so that the calculated first traffic operation information is more accurate.
本发明适用于交通信息采集技术领域,提供了基于视频数据的交通运行信息检测方法、装置及终端设备,该方法包括:确定每帧视频图像中每一车辆的质心坐标;根据第一预设虚拟线和第二预设虚拟线,获得检测距离;根据每帧视频图像中每一车辆的质心坐标、第一预设虚拟线、第二预设虚拟线和每帧视频图像对应的时间戳,获得视频图像序列中既穿过第一预设虚拟线又穿过第二预设虚拟线的所有车辆的第一车辆数目和第一行程时间和;根据检测距离、第一车辆数目和第一行程时间和,计算视频图像序列对应的平均车速,并将平均车速作为所述视频图像序列对应的第一交通运行信息。本发明可以避免统计信息时的误判,进而使计算得到的第一交通运行信息更加准确。
