The invention discloses a road anti-intrusion early warning method based on a millimeter wave radar. The method comprises the following steps: obtaining road vehicle data collected by the millimeter wave radar; according to a set value, judging whether the point target data in the length direction is a short-distance value or a long-distance value; if the distance value is the short distance value, counting short distance points; if the value is a long-distance value, performing long-distance point counting; when the near/long-distance point counting meets the near/long-distance point counting judgment condition, counting the near/long-distance data packets; and when the near/long-distance data packet meets the near/long-distance data packet counting judgment condition, triggering near/long-distance alarm. The method provided by the invention can accurately judge whether there is a vehicle intruding into the set lane and whether there is a false alarm when the vehicle passes through the lateral lane, is simple and convenient, is high in processing speed, can be well applied to a single-chip microcomputer, and effectively solves the problems of missed alarm and false alarm.

    本发明公开了一种基于毫米波雷达的道路防侵入预警方法,包括:获取毫米波雷达采集的道路车辆数据;根据设定值,判断长度方向上的点目标数据为近距离值或远距离值;若为近距离值,则近距离点计数;若为远距离值,则远距离点计数;当近/远距离点计数满足近/远距离点计数判定条件时,近/远距离数据包计数;当近/远距离数据包满足近/远距离数据包计数判定条件时,触发近/远距离报警。本发明涉及的方法可以精准的判断出是否有车辆侵入设置车道和旁向车道过车时是否会发生误报,该方法简单,方便,处理速度快,可以很好的应用在单片机上,有效解决了漏报误报的问题。
