Abstract :
We propose the method for position/pose identification and manipulator navigation to the desired position using one camera and three-dimensional CAD model. In position/pose estimation, instead of simultaneous estimation of all position/pose parameters of target object, the parameters are severally estimated with image features. Thus, our method consists of position parameters estimation; pose parameters estimation and manipulator navigation to the desired position. The position parameters are estimated approximately with image features, and then pose parameters are estimated. And then, a manipulator to the desired position based on the estimates is moved. Both estimation and movement are repeated until the manipulator reaches to the desired position. This gradual approach achieves manipulator navigation concerning automation works with improvement in speed and accuracy.
