The invention discloses a dual-mode hybrid vehicle detection method and device based on radar and geomagnetism, and relates to the technical field of vehicle detection. Collecting magnetic field data of the parking space; when the magnetic field variation of a preset number of continuous cycles is greater than a first threshold value, determining that the parking space enters a new magnetic field stable state; detecting the radar data of the parking space in the new magnetic field stable state, and determining the radar variation of the parking space according to the current radar reference value; and if the radar variable quantity is greater than a second threshold value and the magnetic field variable quantity is greater than a third threshold value, determining a state detection result of the parking space. Whether the parking space enters a new magnetic field stable state or not is determined through the magnetic field variable quantity, interference caused by approaching and leaving of other magnetic substances can be avoided, the current magnetic field reference value and the radar reference value of the parking space are updated in real time, vehicle entering and exiting misjudgment of the parking space caused by multiple interference is effectively avoided, the state of the parking space is accurately judged, and the parking space safety is improved. The parking spaces of the parking lot are accurately managed, and the working efficiency is improved.
本发明公开了一种基于雷达和地磁的双模混合车辆检测方法及装置,涉及车辆检测技术领域。采集停车位的磁场数据;当连续预设数目个周期的磁场变化量大于第一阈值,则确定停车位进入新的磁场稳定状态;检测新的磁场稳定状态下,停车位的雷达数据,并根据当前的雷达基准值确定停车位的雷达变化量;若雷达变化量大于第二阈值且磁场变化量大于第三阈值,则确定停车位的状态检测结果。通过磁场变化量确定停车位是否进入新的磁场稳定状态,可以避免由于其他磁性物质靠近及远离的干扰,并实时更新停车位当前的磁场基准值和雷达基准值,有效避免由于多重干扰导致的停车位的车辆进出误判,精准判断车位的状态,对停车场的车位进行精准管理,提高工作效率。
