We construct a stereo vision system for the motion measurement of tools. We use its prior knowledge of the shape of the tool and the rough motions. Firstly, we extract the image edge features. Secondly, we predict the motion and calculate the features which should be projected on the image. We combine the actual image features and the predicted features. Then we calculate the tool's motion using the relation using RANSAC algorithm. Experiments showed that tool's complex motion could be measured.
