Currently, the car ferry is a special car for ferrying ferry. Before boarding the vehicle needs to buy a vehicle "boat tickets", but always some car owners to save money and fare evasion, the traditional way is checked manually register the license plate number of the vehicle, and then one by one check after boarding, not only efficiency low fare evasion and is prone to leakage phenomenon tickets, ferry company to cause serious economic losses.
With maturing mobile terminal license plate recognition technology, the ferry company to move into the end plate recognition SDK integrated ticketing system, ticket inspectors by integrating a hand-held terminal Our license plate recognition function for each vehicle license plate is scanned boarding recognition, automatic license plate recognition and determines whether the vehicle is normally buy tickets, boarding not only greatly enhance the efficiency, but also to eliminate fare evasion from the source, drain the occurrence of an event ticket. 
Here the mobile terminal introduce the short answer license plate recognition technology:
Moving end plate recognition Android mobile operating system plug-in support. The plug-in uses a mobile phone, tablet camera to photograph the license plate image, and then identify the color of the license plate, license plate number through OCR software. 
End mobile license plate recognition works complete the following steps:
1, image acquisition:, pad and other handheld terminal camera or a video camera the vehicle scanned by mobile acquired image;
2, the preprocessing: noise filtering, automatic white balance, exposure, and gamma correction, edge enhancement, contrast adjustment and the like;
3, positioning plates: scanning performed on the ranks of the image after gradation image subjected to pre-determine the license plate;
4, character segmentation: positioning a rear license plate, by graying, binarization processing in the image, the precise positioning of the character region, the character segmentation and character dimensional characteristics;
5, character recognition: the divided character scaling, feature extraction, the character is determined to match the form of the expression of the character database template standards;
6, the resulting output: output the recognized result in a text format. 
Finally, end mobile license plate recognition technology which features need to have it?
1, to easily identify: license plate recognition distal fast, accurate and stable;
2, simple recognition: "only need to use sweep the camera, video browsing mode quickly identify the license plate" two-dimensional code scanning as fast and accurate identification of license plates.
3, wide recognition: the recognition accuracy of the movable end plate angle of the large license plate recognition.
4, universal recognition: support Android, ios dual-platform application that supports the ARM platform mobile phones and PDA X86 architecture
5, multi-species license plate recognition: blue card, yellow card, trailer license plate, brand new army, police brand, new armed police license plates, coach license plates, license plate embassy, agricultural license plate personalized license plates, license plate entry and exit Hong Kong and Macao, Macao and Taiwan license plate, civil aviation license plates, license plate consulate, license plate and other new energy sources.
End mobile application license plate recognition technology, for the management of vehicles, traffic safety and the maintenance of urban security, implement traffic management automation has practical significance.
