The invention discloses a parking detection method, device and system based on geomagnetism, radar and infrared light sensation, and the method comprises the steps: collecting a geomagnetic signal parameter from a to-be-detected parking space, and respectively collecting a radar radio frequency signal parameter and an infrared light signal parameter when the numerical value of the geomagnetic signal parameter is greater than a preset geomagnetic parameter threshold value; calculating a feedback signal intensity value by using the geomagnetic signal parameter, the radar radio frequency signal parameter and the infrared light signal parameter; and according to the feedback signal intensity value, determining that a vehicle is parked in the to-be-detected parking space or determining that no vehicle is parked in the to-be-detected parking space or determining that the parking state of the to-be-detected parking space is unchanged. According to the invention, the intensity of the feedback signal can be calculated according to the returned magnetic field signal, radio frequency signal and infrared signal, whether a vehicle is parked in the parking space is determined according to the intensity value of the feedback signal, and the parking state of the parking space is detected by combining the intensity values of several different detection signals, so that the situation of false triggering or missing detection can be avoided; and the parking space detection precision and accuracy are effectively improved.

    本发明公开了一种基于地磁、雷达、红外光感的停车检测方法、装置及系统,所述方法包括:从待检测车位采集地磁信号参数,当地磁信号参数的数值大于预设地磁参数阈值时,分别采集雷达射频信号参数和红外光信号参数;利用地磁信号参数、雷达射频信号参数和红外光信号参数计算反馈信号强度值;根据反馈信号强度值,确定待检测车位有车辆停泊或确定待检测车位无车辆停泊或确定待检测车位的停泊状态不变。本发明可以根据回传的磁场信号、射频信号和红外信号计算反馈信号强度,根据反馈信号强度值确定车位是否有车,通过结合几种不同的检测信号的强度值进行车位停泊状态的检测,能避免误触发或漏检的情况,有效提升车位检测的精度和准确率。
