Raspberry Pi Based Road Sign Recognition System with Additional Safety Parameters Using Image Processing

At present situation the Human beings are faced many accidents during the road way transportation. At the same time they lose our life and valuable properties in those accidents. To avoid these problems the system designed with the help of two main processors (Raspberry pi and PIC microcontroller). The Digital image processing plays important role in the sign capturing and detection system. The image processing algorithms to takes the necessary action for resizing the captured signs. The Raspberry pi camera port used to capturing the road signs with image enhancement techniques. The embedded system small computing platform studies the characteristics of speed signs. In that daylight vision time to take the shape analysis for recognizing the signs using edge detection algorithms. After that the night time travelling to detect the speed signs using color enhancement techniques. To avoid the circuit complexity the additional parameters added with the PIC microcontroller likewise automatic headlight dimming system using LDR sensor, vehicle collision avoidance system using ultrasonic sensor and tire pressure measurement system using pressure sensor.
