A smart license plate detection system comprising:
- a smart license plate including:
- a housing having a rectangular structure defined by a back surface, a front surface opposite the back surface, and wall portions extending perpendicularly from a periphery of the back surface to form an inner cavity;
- a display unit disposed at the front surface of the housing, the display unit having a rectangular shape corresponding to the front surface of the housing, and the display unit being spaced inwardly from a periphery of the front surface so as to leave a border region around the display unit, wherein the display unit covers the front surface except for the border region;
- one or more LED strips disposed on the border region so that the one or more LED strips cover substantially the entirety of the border region and extending continuously along the entire periphery of the front surface of the housing and surrounding the display unit, the one or more LED strips being configured to display a status of a motor vehicle;
- at least two circuit boards disposed within the inner cavity and operatively connected to the one or more LED strips;
- a power management assembly disposed within the inner cavity and attached to the housing by one or more supporting components, the power management assembly being configured to supply power to the one or more LED strips;
- an antenna positioned within the inner cavity of the housing to reduce electromagnetic screening when the smart license plate is attached to the motor vehicle, the antenna being configured to receive data from satellites through dedicated RF frequencies;
- and
- a main unit including a microcontroller configured to:
- detect a moving motor vehicle using a detection module;
- capture an RGB image of the motor vehicle to extract details in real time;
- pre-process the captured image by converting the RGB image from three color channels (R, G, B) into a single-channel grayscale format;
- locate a license-plate region within the captured image and segment the license-plate region from surrounding background content;
- recognize a license plate by locating and segmenting the captured image from background content;
- and
- recognize characters on the license plate by detecting image frames and converting the characters into ASCII text;
- a communication block configured to provide data exchange between the smart license plate, the main unit, a cloud server, an application, and an agency;
- wherein the cloud server, the application, and the agency are operatively connected to the main unit through the communication block to enable remote monitoring and processing of vehicle information.
