Development of travel speed detection method in welding simulator using augmented reality

This paper explains about travel speed detection method that can be applied as the welding simulator using augmented reality. In welding process, the travel speed is an important parameter that influences the welding quality. In the future, this simulator can be used in welder training with a relatively low cost. This method uses ARToolkit, OpenGL library, and Autodesk 3Ds Max software for building the simulator. This method is the development of welding simulator that will show the deviation and accuracy of moving marker detection. This method uses differences in distance of the coordinate per unit time algorithm, taken from the amount of frames per second (FPS) of a camera. After this method was successfully built, the measurement data is taken to analyze the accuracy and the number of error in speed detection by the simulator from the actual speed with different light intensity parameter. The result is that the error in speed detection is not too large, so this simulator was successfully built and it can be developed further to get more sophisticated features on welding process in the future.
