【Abstract】 A parameter model of symmetrical binocular visual sensor is investigated with the trigonometricy method.Through analyzing the measurement accuracy of a binocular visual sensor and the error transfer functions of the sensor structure parameters,the effect of the visual sensor structural parameters and the error transfer rules on the sensor measurement result is probed.The error analysis explicitly illustrates the dependence of the visual sensor accuracy on the sensor structural parameters.Lastly,based on the comprehensive consideration for designing an ideal visual sensor,the principle and method of the sensor design are derived.更多还原
