Abstract

The invention discloses a portable vehicle recognition device base on an embedded platform, belonging to the technical field of traffic and vehicle management. A camera, a display or a touch screen, a wireless transmission (GPRS) module, a radio frequency identification card (RFID) reader, a global positioning (GPS) module are arranged on the embedded platform to form a portable device which integrates set data acquisition, data display, data processing, self location, data transmission and communication function as a whole, so that the recognition of licence plate images comprising five key links, such as image acquisition, image preprocessing, licence plate location, character segmentation and character recognition is realized, and the image acquisition and processing are directly completed in the portable device. The device has the advantages of convenient carrying, rapid location, high flexibility, high efficiency, high accuracy, high reliability, low cost and high quality, and is recommended to be used in the field of traffic and vehicle management.

Description

technical field [0001] The invention relates to a portable vehicle identification device based on an embedded platform, which belongs to the technical field of traffic and vehicle management. Background technique [0002] Currently, vehicle management systems based on license plate recognition are widely used in transportation departments and parking lots. The basic principle is: input the image containing the license plate captured by the camera into the PC or embedded digital signal processing (EDSP) system through the video capture card, and then complete the image processing and license plate character recognition by the PC or embedded digital signal processing system , and finally perform operations such as recording or querying corresponding information according to the recognized digitized license plate characters. [0003] The disadvantage of this kind of vehicle management system is that the camera is installed in a fixed position and can only identify and check th...
