%X For the location of multiple license plates often has the problem of that too many candidate of license plate can be extracted and structuring element designed unreasonably, this paper presented a method for multiple license plate location based on separation projective and morphology operation. Firstly, it preprocessed and operated the gray image by horizontal difference; it could located the position for candidate of license plate roughly by separation horizontal projection. Then it detected candidate license plates by morphological block operations. Finally, it located the multiple license plates according to the features of vehicle license plate. The results of experiments show that the method in the text can reduce the quantity of candidate license plates largely and have higher accuracy and efficiency.
