GaiaField（Pro）Portable Hyperspectral Imaging System

The GaiaField (Pro) portable hyperspectral system is an ultra-portable

hyperspectral imaging instrument independently developed and designed by

Shuangli Hepu with independent technical intellectual property rights (patent

number: 2015105650509). The system covers visible light to short-wave infrared

bands. The built-in processor can be controlled by mobile phones, iPads, laptops

and other terminal devices to enable the system to perform real-time image

acquisition scanning, real-time calibration, and real-time result output. On the basis

of obtaining the target image information, it can also obtain spectral information

of hundreds or even thousands of bands to achieve the \"unification of images and

spectra\" of the target.

The GaiaField (Pro) system is light and flexible, has excellent battery life, is

intelligent, has complete data analysis and processing functions, and can monitor,

calibrate, and output inversion results in real time. It is widely used in outdoor and

laboratory applications. For example: military fields such as target detection and

identification, camouflage and anti-camouflage, remote sensing of ground objects

and water bodies (water quality monitoring), modern precision agriculture (plant

phenotype monitoring) and other ecological environment monitoring fields, criminal

investigation, cultural relics protection (authenticity identification), biomedicine

(cell property classification and identification), plastic waste (classification and

identification), industrial sorting of tobacco leaves (quality optimization), chemical

gas combustion flame (composition determination and discrimination), geological

ore analysis, oil and gas rock formation fluorescence analysis, biomedicine, material

performance testing and other fields.

Imaging of jujubes for post-harvest winter SSC monitoring and shelf life analysis using hyperspectral imaging. The

predicted maps provide the spatial evolution of SSC at different maturity and shelf life stages. SPA

LIBSVM achieved an acceptable accuracy of 89% for shelf life analysis and 91% for mid-ripe and ripe fruits, respectively.

Based on the present results, hyperspectral imaging can be used as a non-destructive analysis technique for monitoring

the quality and shelf life of jujubes during the post-harvest winter.

The method of extracting the best hyperspectral features from hyperspectral images of wheat field trials with different

nitrogen application rates, planting densities and varieties was used to monitor wheat leaf biomass. The collaborative

interval partial least squares method (SIPLS) and the successive projection algorithm (SPA) (SIPLS-SPA) were proposed.

The work demonstrated the potential agricultural applications of extracting other plant traits from hyperspectral data in

the future.

Hyperspectral imaging technology can observe images in the range of visible light to near-infrared light. In addition,

this can be done without damaging the painted cultural relics. The optimal principal component image is fused with

the true color image to obtain the painted cultural relic image, thereby mining the pattern. The pattern information of

painted cultural relics that is not easily observed by the human eye can be automatically and effectively mined through

hyperspectral images.

Firmness and soluble solids content (SSC) are two important internal characteristics of plums and are also two key

indicators for determining the maturity and harvest period of plums. Hyperspectral imaging technology is used to nondestructively measure SSC and firmness of fruits.

Prediction and measurement of SSC (a) and hardness (b) by CARS-MLR model

It can monitor the moisture content distribution of tobacco strips in real time and can also be promoted and applied in

monitoring the moisture content of stored tobacco strips, the changes in water loss of roasted tobacco strips, and the

uniformity detection of tobacco flavoring application.
