本文描述了一种在实际系统中将图像从具有相对运动的粒子转移到二值图像的方法，其中图像中的粒子被单独分离。运动粒子的图像由光学图像捕获设备生成。粒子运动对图像的影响要么通过仪器最小化，要么通过软件程序进行校正。该方法适用于与静态背景有明显区别的粒子图像。ISO？13322-1中描述了二进制图像的进一步处理，然后将其视为静态图像。与静态图像分析系统相比，动态图像分析系统能够测量更多的粒子。本文件提供了使用颗粒标准物质进行粒度分布测量的仪器鉴定指南。本文档介绍了粒子之间的相对运动、粒子运动对图像的影响（运动模糊）、沿光轴的运动和位置（景深）以及粒子相对于相机的方向。

This document describes a method to transfer the images from particles having relative motion to binary images within practical systems, in which the particles in the images are individually separated. Images of moving particles are created by an optical image capture device. Effects of particle movement on the images are either minimized by the instrumentation or corrected by software procedures. This method is applicable to the particle images that are clearly distinguishable from static background. Further processing of the binary image, which is then considered as static, is described in ISO 13322-1. A dynamic image analysis system is capable of measuring a higher number of particles compared to static image analysis systems. This document provides guidance on instrument qualification for particle size distribution measurements by using particulate reference materials. This document addresses the relative movement of the particles with respect to each other, the effect of particle movement on the image (motion blur), the movement and position along the optical axis (depth of field), and the orientation of the particles with respect to the camera.
