Description

technical field [0001] The invention belongs to the technical field of vehicle detection, and relates to a geomagnetic parking space detector and a detection method thereof. Background technique [0002] With the rapid development of social economy, the number of urban cars increases sharply, which brings the problem of parking difficulties. Real-time acquisition of parking space occupancy information can effectively help guide urban traffic, reduce the time spent by drivers looking for parking spaces, and at the same time reduce the energy consumption of cars on the way to blindly search for parking spaces, saving time and resources. [0003] At present, the detection of parking spaces mainly adopts ultrasonic detection, infrared detection, image recognition and geomagnetic detection. The ultrasonic detector is small in size and easy to install, but it must be placed on the top, the installation conditions are limited, and the installation cost increases accordingly; the d...
