Application of License Plate Number Recognition Based on Deep Learning Method in Intelligent Building Security System

Intelligent building is the inevitable outcome of information technology in today's world, and people's safety awareness is also improving with the development of society, and the safety issue has become an important proposition that everyone pays attention to. License plate number recognition technology is an important part of intelligent building security system, which plays an important role in the field of vehicle identification. This design is based on the deep learning method to realize the license plate recognition in the field of vehicle identification, including the preprocessing of license plate image, the location of license plate area, the segmentation of license plate characters and the recognition of license plate characters. The test shows that the license plate number recognition system designed this time can effectively and accurately recognize the license plate number in the image, and can effectively identify the identity.
