The invention discloses a dynamic traffic information acquisition method and system based on binocular stereo vision, and relates to the technical field of intelligent traffic, and the method comprises the steps: carrying out the layout of binocular vision equipment based on a target task; obtaining an original scene image through binocular vision equipment; carrying out stereo matching to obtain a stereo vision image set; based on a target recognition algorithm, carrying out segmentation marking on the pixel region to obtain a partition mark chain; activating a point cloud coordinate encoder, calculating a pixel point three-dimensional coordinate corresponding to the partition mark chain, and generating a multi-object point cloud data set; performing fitting projection based on the multi-object point cloud data set to obtain multi-object positioning information; the binocular vision device continuously collects a target range, obtains multi-frame object positioning information, and obtains dynamic traffic information of the target range. The technical problem that in the prior art, a pure video image recognition mode cannot meet the dynamic traffic information collection requirement easily is solved, and the technical effect of improving the dynamic traffic information collection accuracy is achieved.

    本发明公开了基于双目立体视觉的动态交通信息采集方法及系统,涉及智慧交通技术领域,该方法包括:基于目标任务进行双目视觉设备的布设;通过双目视觉设备,获取原始场景图像;进行立体匹配,获取立体视觉图集;基于目标识别算法,进行像素区域的分割标记,获取分区标记链;激活点云坐标编码器,计算分区标记链对应的像素点三维坐标,生成多对象点云数据集;基于多对象点云数据集进行拟合投影,获取多对象定位信息;双目视觉设备对目标范围进行连续采集,获取多帧对象定位信息,获取目标范围的动态交通信息。本发明解决了现有技术中纯视频的图像识别方式难以达到动态交通信息采集需求的技术问题,达到提高动态交通信息采集准确性的技术效果。
