Problems solved by technology

[0005] Changes in the temperature and humidity of the parking space environment will cause changes in the actual judgment of the parking space status data. If the preset judgment of the parking space status data is used to determine the occupancy status of the parking space, it will cause the parking space detection device to misjudge the parking space status and reduce the accuracy of the parking space status detection.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for calibrating a reference value of a parking space state. Background technique [0002] At present, with the popularization of motor vehicles, there are more and more parking lots. When the existing parking lots manage the parking spaces, they will use the parking space detection devices with geomagnetic detectors, ranging sensors or microstrip antennas to monitor the parking spaces. status is checked. [0003] In the related art, in the process of detecting the state of the parking space by the parking space detection device, the data collected by the geomagnetism detector, the ranging sensor or the microstrip antenna will be compared with the preset judgment data of the parking space state in the parking space detection device to determine the status of the parking space. occupancy state. [0004] In the process of realizing the present invention...
