| Abstract: | In order to improve the measurement precision for visual measuring system,the influence of binocular vision structure was investigated.A structural parameter model of binocular visual measuring system was investigated with the trigonometric method.Through analyzing the measuring accuracy of the measuring point in binocular visual measure system,the effect of the structural parameters and the error transfer rules on the visual measurement were probed.According to simulation results, optimal value range of structural parameters is supplied while the error is small.Enough theoretical research is offered for optimization design of binocular visual measure system. |
