项目摘要

This research project was carried out in 1993 and 1994 and the following results are obtained.(1)Design and theoretical analysis of sensor-elementIn order to simultaneously detect the position vector and the unit normal vector of a measured point in non-contact, a sensor-element which has one emitting optical fiber with micro collimator lens and eight receiving optical fibers was proposed. And its characteristics and performance were clarified by theoretical analysis.(2)Development of the probeIn order to avoid the shadow effect, a probe which is consists of the thirteen sensor-elements is designed. And, in this project, a probe with the five sensor-elements was developed.(3)Construction of automatic calibration systemAn automatic calibration system for the developed probe was constructed by controlling a NC index and a three coordinates measuring machine by an external computer.(4)Development of data acquisition system and data processing systemThe data acquisition system which dynamically selects a sensor-element to project a beam from the emitting fiber and feeds into signals obtained from receiving fibers was developed. In addition, the data processing system which recognizes the position vector and the unit normal vector of a measured point from acquired data.(5)Development of autonomous measurement systemThe measurement system which autonomously measure an unknown model is developed by combining the developed probe, the data acquisition system, the data processing system, and a three coordinate measuring machine.(6)Development of computer model constructing systemA basic system which recognizes surfaces (flat plane, cylinder, sphere, circular cone, circular ring, and sculptured surface) forming a physical model and construct the shape as computer model is developed.

该研究项目于1993年和1994年进行，获得了以下结果：(1)传感器元件的设计与理论分析为了在非接触情况下同时检测测点的位置矢量和单位法矢量，提出了一种由1根带微准直透镜的发射光纤和8根接收光纤组成的传感器元件。并通过理论分析阐明了其特点和性能。(2)探头的研制为了避免阴影效应，设计了一种由13个传感器元件组成的探头。并且，在这个项目中，开发了一个具有五个传感器元件的探针。(3)自动标定系统的构建通过外部计算机控制数控指标和三坐标测量机，构建了所研制探头的自动标定系统。(4)数据采集系统和数据处理系统的发展数据采集系统是动态地选择传感器元件从发射光纤发射光束，并将接收光纤获得的信号输入到数据采集系统中。此外，数据处理系统从采集的数据中识别出测点的位置向量和单位法向量。(5)自主测量系统研制自主测量系统是将研制的测头、数据采集系统、数据处理系统和三坐标测量机相结合，研制出对未知模型进行自主测量的测量系统。(6)计算机模型构建系统的开发。开发了一个基本系统，可以识别形成物理模型的表面（平面、圆柱、球体、圆锥、圆环和雕刻表面），并按照计算机模型构建形状。
