【Abstract】 The measurement accuracy of a binocular stereo visual sensor in relation to the values of the sensor structure parameters and their errors has been probed into,with respect to modelling the sensor with the trigonometric stereo disparity method.How each error component contributes to the integration measurement error of the sensor has been investigated in details.The effect is then denoted by the transfer function of the error component.Through exploring the error transfer functions the reasonable value intervals of the sensor parameters are yielded.Then the principle and method of the sensor design are derived.
【Key words】 binocular stereo visual sensor； error transfer function； accuracy analysis； structure parameters；
