摘要

激光显微摄影和激光全息摄影测粒技术在工程中应用的最大障碍是微粒影象的处理

由于激光摄影测粒技术含有的信息量很大

人工判读既费时

结果还受检测者的视差、熟练程度、疲劳情况等诸多因素的影响。特别当微粒离焦时

人工判读只能将其舍掉

无法加以利用。然而

在激光摄影测粒中

存在着大量的离焦微粒影象

可以根据三维判读技术加以利用[1]。因此需要解决激光微粒影象的图象处理技术。

Abstract

An approach

known as Edge Tracking Method

has been developed in particular

which searches out the outer edge and the central spot edge of the coherent image of a particle.The processing procedure of the digital images and its program have been worked out in detail.Finally

the outer size and the central size a particle image are determined by means of the presented technique

then the particle size and its position are calculated by means of the Three-Dimensional Judgement Technique.The results obtained are reasonable.
