摘要：

In this paper, a technique to measure the locations and orientations of apertures, and their diameters, on the spout nozzle of an engine is presented and a complex measuring apparatus designed for the purpose is discussed. This consists of an area CCD camera, an image acquisition card, stepper motors, optical and mechanical units and a computer system for data acquisition and control. Results on the performance of the system are presented. (C) 2002 Elsevier Science Ltd. All rights reserved.
