摘要
生物散斑是一种利用激光在物体内部的折射与反射来反映其内部信息的光学无损检测技术。生物散斑成像设备和图像处理算法不断改进,应用领域也在逐步扩大;但由于干扰因素的存在,建模精度仍是研究者关注的重点。本文较为详尽地整理了散斑图像处理算法,并对生物散斑技术在水果品质检测中的应用进行调研,归纳主要的成像设备,提出改进意见,旨在为后续研究提供启发。
Biospeckle is an optical non-destructive testing technology that uses laser refraction and reflection inside the object to reflect its internal information. Biospeckle imaging equipment and image processing algorithms are constantly improved, and the application fields are gradually expanding. Due to the existence of interference factors, the precision of modelling is still the focus of researchers at present. The speckle image processing algorithm is reviewed in detail, and the application of biospeckle technology in fruit quality detection is investigated. The main imaging equipments are summarized and suggestions for improvement are proposed to provide inspiration for future research.
