Abstract: Rear View Convex mirror are used in vehicles to get the visibility of back sides. These mirrors are very important as they are very crucial for safety purposes. Therefore the parameters of the mirrors must be under a limit. Distortion factor is one of the parameter of rear view convex mirror. Current method for calculating Distortion factor is manual. In this paper, a novel technique for automated calculation of distortion factor is proposed using image processing techniques. Edge detection is done using particle swarm optimization and line segment is done using Progressive probabilistic Hough transform. The result obtained by proposed method is fast and accurate. Major advantage of the proposed method is that it is flexible. Various mirrors have been used to verify the proposed techniques.
