The embodiment of the invention provides a traffic information collection method and device applied to a road section scene and electronic equipment. According to the embodiment, after the first position information, collected by the visual sensor, of the first object in the first lane at the first time point is obtained, the first position information is corrected through the lane reverse slope k of the first lane in the image coordinate system corresponding to the visual sensor, and linear distortion is effectively corrected through the correction mode; and accurate second position information is obtained. And in the process of mapping the second position information to the global coordinate system, the deviation of mapping the second position information to the global coordinate system is compensated through the deformity elimination mapping relation, so that nonlinear distortion generated in the mapping process is effectively corrected, and more accurate first global position information is obtained. Therefore, the fusion track, obtained through fusion, of each object can accurately reflect the actual motion track of each object, traffic information is accurately collected, and intelligent traffic control is achieved.
本申请实施例提供应用于路段场景下的交通信息采集方法、装置及电子设备。本实施例中在获得该视觉传感器采集的第一对象在第一时间点下在第一车道的第一位置信息之后,利用第一车道在该视觉传感器对应的图像坐标系中的车道反斜率k矫正第一位置信息,这种矫正方式实现了有效矫正线性畸变,获得精准的第二位置信息的目的。并且在将第二位置信息映射至全局坐标系的过程中,通过消畸映射关系补偿第二位置信息映射至全局坐标系的偏差,实现了有效矫正映射过程中所产生的非线性畸变,获得更准确的第一全局位置信息。从而使得通过融合获得的各对象的融合轨迹能够准确反映各对象的实际运动轨迹,精准地采集交通信息,实现智能交通管控。
