Abstract: This paper proposes a fully automated angular measurement method for various applications using hit or miss morphology technique. The morphological transformation is analyzed for the recognition of pattern and the hit-or-miss transform indicates the positions where a certain pattern occurs in the image. The extracted position in the image is mapped into a line graph for angular measurement. The efficiency of the proposed technique is justified by applying it in various applications such as instrument panel board interfacing, angular speed measurement and angular orientation of a robotic arm. From the results, it is evident that the proposed system provides a better performance and cost effectiveness.


Keywords: Angular measurement, Hit or miss transform, Image processing
