Raspberry Pi based vehicle collision avoidance system

Vehicle collision avoidance and obstacle detection system is one of the most critical factor in the automotive field. In the present, most of the vehicles enable an alert system which acts as a safety feature for the passengers. In this work, advanced navigation system which detects and avoids the object, is used in autonomous vehicles to safely navigate through the path. This system detects the obstacle in front of the vehicle, alarms the system and moves away. Camera is used for the purpose of detecting moving or stationary objects. The ultrasonic sensor is enclosed with this system to compute the distance of real-time moving and the stationary object. The main work contributes the detection of obstacles ahead of the vehicle. The alarm is given to the system in the vehicle regarding the obstacle in front so that the system helps in collision avoidance. In this work, the distance between the vehicle and obstacle is measured by the ultrasonic sensor and object detection is done by the camera. By fusing both these sensor values the obstacle is detected and the distance is also accurately measured.
