| Abstract: |
| Aiming at the precision measurement in furcation tendon of a novel unitary flexible hinge, this paper develops a two-dimensional image collection system. Using MATLAB software, image processing program and the least mean-square fitting algorithm of plane distance are designed. The existed problems and error derived from experiments are analyzed in theory. The experimental results show that the measuring method is correct in theory and can be implemented. The measurement precision of this system can reach 8 μm, and increases measurement precision. |
