Raspberry Pi Vehicle Gateway System with Image Processing based Authorization Detection using IoT

Vehicles intentionally or unintentionally enter a restricted area and commonly termed as trespassing. Unauthorized entry offences have been common in most of the countries. In order to keep a check on this various techniques have been followed. This work illustrates the method to avoid trespassing through proper detection of vehicles. The gateway will be integrated with the camera which will detect the vehicle and detect the number plate. Using IoT the collected data sent to an online server is compared with the pre-existing data. If the number plate is an authorized one, gateway automatically opens for the vehicle to enter. If it is detected as unauthorized vehicle then the gate will remain closed and a buzzer alarm will be activated. Through the mobile app admin can add the number plate details to the device. The detection process is carried out by processing the images of the number plates captured by the camera connected to the gateway. Implementation of this process with Raspberry Pi with image processing and networking through IoT resulted in highly efficient system.
