VIS/NIR高光谱成像在中国云冈石窟砂岩风化状况分布研究中的进展
高光谱 云冈石窟 粉状风化
2012/4/11
云冈石窟大部分雕凿在长石石英砂岩上,因受环境、岩性等因素影响,目前风化状况严重,其中主要为粉状风化。基于高光谱成像技术研究云冈石窟砂岩风化状况的整体有效评估方式,采集目标物400~1 000 nm的高光谱数据,采用对数残差法进行归一化处理,参照归一化处理后的反射率数据,按照这区间的反射率分布范围将风化程度分为强风化和弱风化。同时在envi平台下对砂岩的风化状况分布进行分级可视化表述。将可视化结果与...
Vis/NIR hyperspectral imaging for detection of hidden bruises on kiwifruits
Actinidia deliciosa principal component analysis support vector machine
2014/2/25
It is necessary to develop a non-destructive technique for kiwifruit quality analysis because the machine injury could lower the quality of fruit and incur economic losses. Bruises are not visible ext...
洋梨硬度的便携式可见/近红外漫透射检测技术(Evaluation of European Pear (Pyrus communis L.) Firmness Based on Portable Vis/NIR Transmittance Technique)
洋梨 硬度 近红外光谱
