| Abstract: | The factors,which influence measuring precision of binocular vision sensor, are analyzed according to the sensor operating principle. The relation between the coordinates of the object and the coordinates of the image is the complex nonlinear mapping in the sensor. The mathematical model of the binocular vision sensor can't be accurately described by expressions.Therefore, this paper presents a new modeling method for binocular vision sensor based on neural network.The numerical experiment shows that the neural network is suitable for building up a nonlinear model of the binocular vision sensor. This method is simple, easy to realize. A higher measuring precision can be obtained. |
