Abstract
To detect the quality of jujube in outdoor with hyperspectral, part of the polarized light is formed by the absorption and scattering of atmospheric and jujube. Polarization dimension contains red jujube of fine quality information, by increasing the polarization spectrum detection, further improve the detection accuracy, research methods, the characteristics of high spectral band orthogonal polarization imaging technology, to obtain samples of jujube different orthogonal polarization direction of hyperspectral images. Texture features were extracted by PCA wavelength ratio. The basic processing methods of spectral region correction and spectral smoothing were used to compare the characteristic absorption peak of 992.65nm, 1188.96nm, 1449.96nm, 1107.68 nm and 1294.68nm in both indoor and outdoor southern xinjiang jujube. Results, comparative indoor and outdoor nearly hyperspectral images found on the ground, jujube and reflection spectral absorption peak position unchanged, spectrum waveform similar, affected by different band size is different, characteristic peak place have obvious difference, the longer the wavelength, the greater the difference. The hyperspectral images of parallel and vertical components of the target were obtained, and the orthogonal differential polarization spectrum information was obtained. The preliminary results were obtained by fine remote sensing of quality of jujube. The results show that the quality information of jujube can be obtained by using the orthogonal polarization imaging technology of high spectral characteristic band. It provides an important reference for monitoring the quality change information of large area jujube.
