By analyzing traditional method of projection position, we present a location method based on the car edge examination and color information in this paper. The characters are divided up by the traditional methods, the template storehouse is made artificially; and the characters are distinguished. The experiment results show that: compare to the traditional method of projection, the localization method...
Aiming at the problem of precision and real time in traditional methods to horizontal tilt correction of vehicle license plate, an approach based on matchstick model is presented. The principle is to get the correct license image from its tilt character line. A matchstick model is built up by abstracting the features of characters. By rotating the image with a certain degree, we can find whether it...
This paper presents a novel approach of license plate location. The proposed algorithm involves the following three steps. First, the vertical edges of the vehicle image are extracted by Sobel operator. Second, HSV color space and integral image are employed to locate candidates in yellow license plates and non-yellow license plates. Finally, connected component analysis is to locate the region of...
EACWS (Embedded Advance Collision Warning System) is an important part of ITS (Intelligence Transportation System). It is mainly based on monocular vision algorithms, and high-speed DSP processor, real-time to complete front vehicle distance detection, and send out early warning signals to ensure driving safety.
