Description

technical field

[0001] The invention belongs to the field of measurement and detection, and in particular relates to a detection device and a detection method for a parking space in a parking lot. Background technique

[0002] At present, the parking space detection device in the parking lot generally adopts a geomagnetic detection method or a combination of sound waves, infrared, pyroelectric and other methods. The method of geomagnetic detection belongs to the indirect measurement of the disturbance of the vehicle to the geomagnetic field. Its advantage is low power consumption. However, due to the inconsistency of the disturbance of the vehicle to the geomagnetic field, it cannot distinguish whether there is a parking space or not. Factors such as the iron content of the vehicle, the age of the vehicle and other factors lead to inconsistencies in the values ​​measured at the same location of the same type. At the same time, the geomagnetic detection method also involves ...
