Abstract
The invention discloses a license plate recognition algorithm based on image processing technology. The algorithm comprises the following steps: 1) selecting a target area, and dividing the target area into a background recognition area and a feature recognition area; 2) extracting a color from the background recognition area as the background color of a license plate; 3) recognizing and extracting a character, letters and digits in the feature recognition area as the content of the license plate; 4) synthesizing the background color extracted in step 2) and the license plate content extracted in step 3) via a Fourier algorithm; and 5) sending the license plate content synthesized in step 4) to a cloud server for storing. The accuracy and the universality of the license plate recognition algorithm are improved by adopting a brand-new algorithm structure design.
