查询词典 waveband

The relativity between hyperspectral images of different waveband is differ from each other, contraposing this characteristic, this paper presents a lossless compression algorithm of hyperspectral image which is based on searching the optimal couple prediction wavebands.

摘要该文针对超光谱各波段成像图像之间的相关性强弱程度互不相同这一特点，提出了基于搜索最优双预测波段的超光谱图像无损压缩算法。

Application and research of multi-waveband measuring technology in space object detection.

多波段测量技术在空间目标探测中的应用研究。

The results show that the normal spectral emissivity of ply yarn carbon fiber and short cut felt performs are higher than weave sample in the whole test waveband,and the values of normal total emissivity are 0.910 and 0.888 respectively,w...

结果表明，股线型和短切毡型碳素纤维预制体的法向光谱发射率在整个测试波段内均大于编织布状样品，股线型和短切毡型碳素纤维预制体的法向总发射率分别为0.910和0.888，均高于编织布样品。

Then the waveband was divided into two parts to develop calibration model using partial least square method for soluble solids content to remove the effect of the skin and the results indicated that the measurement results was not be enhanced. However, the difference of calibration results in the wavelength of 650-950nm with the r of 0.949, the RMSEC of 0.292 for intact watermelon and with the r of 0.973 and the RMSEC of 0.214 for skin-peeled watermelon indicated that the influence of skin is not very serious and the intact watermelon spectra also can get satisfied calibration result. 5. Vis/NIR spectroscopy nondestructive detection needs high-energy light source, so differences of diffuse transmittance spectra with different light intensity (600W, 1000W) were detected and effects of light intensity on spectra and calibration results were compared.

针对西瓜果皮较厚的特点，对去皮西瓜与带皮西瓜进行对比试验研究，发现果皮对光谱的影响主要集中在可见光部分(650-750nm)，对可溶性固形物含量采用偏最小二乘法进行分段建模并没有有效消除果皮的影响，对比研究去皮西瓜与完整西瓜光谱在650-950nm范围内的建模结果，完整西瓜二阶微分光谱校正模型相关系数r为0.949，RMSEC为0.292，去皮西瓜校正模型相关系数r为0.973，RMSEC为0.214，果皮对建模结果的影响并不严重，完整西瓜的建模结果可以满足检测要求； 5。
