Paper Abstract

A novel four-eyes robust optical fiber distance and orientation measuring integrated proximity sensor is presented in this paper. The transducer can measure the distance and orientation of the objects surface at the same time, and is insusceptible to the fluctuation of the optical power output and variation of the object surface's reflectivity. The transducer's measuring attitude control is one of the important content studied in this paper. Based on the prior research, which verifies that the measuring pose does exist and there is only one such attitude, further study on optimize the attitude adjusting control is done to improve the systems real time performances. In view of the complexity of the transducer's mode, an improved BP neural network data processing method is proposed to solve the difficulty in real time data processing. By partition the multi-output BP network into several single output ones and subsection the range of input variables, the sensor's accuracy of pose estimation is significantly increased.
