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 identification system and method. The method comprises the following steps: detecting magnetic field change data of the vehicle entering by using athree-axis geomagnetic sensor, processing the data by using a finite state algorithm to obtain a vehicle entering signal, and driving a camera to photograph a license plate part by using the signal;converting the picture data including the license plate obtained by photographing into a one-dimensional array, and uploading the array content to a server end in a data stream mode by utilizing a method of sending a TCP data packet by an NB-IoT module; and finally, restoring the data stream into a picture format through specific processing at the server end, identifying the content of the license plate by using a specific license plate identification algorithm, and finally storing the result in the form of pictures and character strings at the server end. Compared with the prior art, the side parking detection and identification system and method has the characteristics of high pertinence and high recognition precision in the side parking scene, and realizes the automation and the intelligence of the 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...
