Vision Sensor : Distance and Angle

Abstract: The objective of the thesis is to design a real time machine vision system using a smart camera to determine the distance and viewing angle from a target board.  A machine vision algorithm is designed and, by calibrating that system to a target board, it is possible to measure the distance and viewing angle.  The smart camera is a Matrox IrisGT running Windows XP Embedded.  Image pre-processing, labelling, feature extraction and a triangulation technique are used in the algorithm in relation to the measurement.  By using the Visual C++ library and Matrox imaging library this application is developed and deployed in the smart camera.  At a later stage, a serial communication is established between the smart camera and a PC and the results of the distance and angle are shown using a distance scale and angular meter in LabVIEW.  The application is analysed at different resolutions to check the frame rate and power consumption of the smart camera for the application, also the accuracy of position measurement and latency of the system is measured.
