Image processing technologies in intelligent transportation systems

摘要

Nowadays in intelligent transportation systems (ITS), information gathering depends heavily on visual information. Image processing technologies (IPT) play a key role. After a brief introduction of ITS, IPT is illustrated from three aspects: image sensor, image processing methods and image processing system. Among many applications for image processing in ITS, the paper presents a roadside example, license plate recognition (LPR). Attention is, centered around two aspects of LPR: plate character isolation and plate character recognition. Lastly, the paper indicates the trends of image-processing technologies in ITS.
