Introduction of GB/T 21649.2-2025

本文件描述了一种在实际系统中将具有相对运动的颗粒转换为二值化图像的方法，其中图像中的颗粒被分离成独立个体。运动颗粒的图像由光学图像采集设备创建。颗粒运动对图像的影响可以通过仪器最小化或通过软件程序进行校正。本文件适用于与背景有明显区别的运动颗粒图像。后续分析中，这些二值图像可视为静态图像，其表征方法见GB/T 21649.1—2024。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颗粒。本文件为使用颗粒标准样品进行粒度分布测量仪器鉴定提供指导。本文件详细讨论了颗粒的相对运动、颗粒运动对图像的影响（运动模糊）、颗粒沿光轴上的移动与位置（景深）以及颗粒与相机的相对运动方向。
