Raspberry-Pi Based Road Sign Recognition And Automatic Headlight Dimming Systems with Vehicle Collision Avoidance Using Image Processing

Human beings like enjoying their life, and that’s why they invented and created the vehicles. But towards enjoying their environment, they suffer with accidents and lose valuable lives and properties. For avoiding rash driving of the drivers and from accidents, the system has designed with the help of two main controllers Raspberry pi and PIC microcontroller. The Digital image processing takes major place in a road sign recognition system. The system reads and recognizes the speed signs using image processing techniques based on shape and dimension analysis. During night time travels the system can easily identified the road signs by colour shape detection. Raspberry pi processor provides an interface between sensors, database and image processing results. Apart from this an another unit i.e. the PIC controller unit gives a major play to the vehicle by controlling the small signaling parts, which may cause to an major issue in future for example puncher of tires, headlight failures etc. To avoid these issues while driving, the indication of tire pressure is done displayed in the screen and the headlight dimming is controlled by the use of LDR sensor. As well as, in addition to this system have added the control of motors through ultrasonic sensors which are very helpful to avoid accidents and it maintains a gentlemen distance to the fronted vehicles. Hence through this, the performance of the vehicle is controlled automatically according to the situation.
