The embodiment of the invention provides a parking space state detection method and system. The method comprises the steps of obtaining magnetic field data of a parking space based on a magnetic fielddetection method; and if the magnetic field data is in a misjudgment threshold interval, judging the final state of the parking space based on the combination of the magnetic field detection method and the millimeter wave intensity detection method, otherwise, judging the final state of the parking space based on the magnetic field detection method. The embodiment of the invention provides the parking space state detection method and system. Under the condition that misjudgment may exist in magnetic field detection, the parking state is detected in a millimeter wave intensity and magnetic field combined detection mode, a comprehensive judgment result is given through combined judgment of the two detection modes, the influence of magnetic field disturbance and adjacent parking space interference can be well reduced, and the detection rate of the parking space state and the adaptability of different parking spaces are improved.

    本发明实施例提供一种车位状态检测方法及系统,方法包括:基于磁场检测方法获取车位的磁场数据;若所述磁场数据处于误判阈值区间,则基于所述磁场检测方法和毫米波强度检测方法联合判决所述车位的最终状态,否则,基于所述磁场检测方法判决所述车位的最终状态。本发明实施例提供的车位状态检测方法及系统,在磁场检测可能存在误判的情况下,通过采用毫米波强度和磁场联合检测的方式对停车状态进行检测,通过两种检测方式的联合判决,给出一个综合判决结果,可以较好的降低磁场扰动和临车位干扰的影响,提高车位状态的检测率和不同车位的适应性。
