Embodiment Construction

[0070] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0071] A side parking detection and identification system provided by the present invention includes a geomagnetic detection module, an MCU (Microcontroller Unit, microcontroller unit), a camera module, an NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things) module and a server.

[0072] The geomagnetic detection module is used to collect the magnetic field data in the X, Y, and Z three-axis directions in the Cartesian coordinate system of the side parking space, and send the collected data to the MCU;

[0073] The MCU receives the magnetic field data sent by the geomagnetic detection module, and obtains the signal of whether there is a vehicle entering through the finite state machine and the threshold detection algorithm. When a vehicle is detected, it drives the camera module to take pictures; and receives the fron...

Abstract

The invention discloses a side parking detection and recognition system and method. The invention uses a three-axis geomagnetic sensor to detect the magnetic field change data of vehicles entering, uses a finite state algorithm to process the data, obtains a signal of the vehicle entering, and uses the signal to drive a camera to take pictures of the license plate. The picture data including the license plate obtained by taking pictures is converted into a one-dimensional array, and the content of the array is uploaded to the server in the form of a data stream by using the NB‑IoT module to send TCP packets. Finally, the data stream is restored to the picture format after specific processing on the server side, and the content of the license plate is recognized using a specific license plate recognition algorithm, and the final result is saved on the server side in the form of pictures and strings. Compared with the prior art, the present invention has the characteristics of side parking scene pertinence and high recognition accuracy, and realizes automation and intelligence of side parking information management.

Description

technical field [0001] The invention belongs to the field of vehicle information management, and in particular relates to a side parking detection and recognition system and method. Background technique [0002] With the economic development, the number of vehicles continues to increase, and the problem of difficult parking needs to be solved urgently. At present, there are many large parking lots in urban areas for vehicles to park, but their locations are fixed and sparsely distributed, making it difficult to cover all parking needs. In the daily life of the majority of residents, it is more common to see scattered roadside side parking scenes. [0003] Some existing electronic vehicle information management systems have been widely used in parking lots, such as camera-based automatic lifting barriers and license plate information recognition at the entrance of the parking lot. However, in the scene of side parking on the roadside, due to the high mobility of vehicles, l...
