The invention discloses a traffic flow statistical method and device based on DVS events. The method comprises the following steps: acquiring DVS events in a plurality of time periods; and comparing the DVS event of the i-th time period with the DVS event of the (i-1)-th time period to determine the vehicles passing by the lane in the i-th time period according to the change of the DVS events, and accumulating the vehicles passing by the lane in a plurality of time periods. The method has the advantages of being advanced in technology, good in method real-time performance, small in device number, easy to install, convenient to construct and flexible in application.

    本发明公开了一种基于DVS事件的交通流量统计方法及装置,该方法包括:获取多个时间段的DVS事件;将第i个时间段的DVS事件与第i‑1个时间段的DVS事件比较以依据DVS事件的变化确定车道在第i个时间段内通过的车辆,并累计车道在多个时间段内通过的车辆。本发明的有益效果:技术先进、方法实时性好、装置数量少、安装简单、施工方便、应用灵活。
