Abstract

A method for measuring position and orientation of an object was determined by making use of image processing technique. The position of light sources gives a geometrical constraint between them. Three light sources was designed and constructed at appropriate positions with respect to camera (webcam), the processed/programmed images directly give the coordinate values (x and y) of each of the light spot which were used in calculating their distances apart using square root of the both coordinates. The approach is based on measuring/calculating distances and determining the object orientation. The proposed research (position-orientation masking x, y, ) would be useful, in-real world for robotic applications such as navigation of indoor mobile robots and machine vision. The results show that when hand moved to 30° right to the webcam, it was seen that the orientation obtained from the tracking was 30.9°, as the hand moved in the other direction (left). The experimental result shows the direction that an object moved in degrees of angle which compared with the calculated results in order to determine the orientation ( ). Based on this result on the error of measurement, it shows that image processing technique is sufficient for such purposes.
