Gaiasky-mini Hyperspectral Imaging Camera

GaiaSky-VIS/NIR camera provide extremely high resolution images by scanning and taking multiple images to construct a hyperspectral datacube. Hyperspectral imaging devices (GaiaSky) for lens scanning obtain slit spectra by projecting a strip of the scene onto a slit and dispersing the slit image with a prism or a grating. In lens scanning, each two-dimensional (2- D) sensor output represents a full slit spectrum (x,λ). The NUC integrated into the system to control system operation ,data acquisition, and analyze , so the spatial dimension is collected through the scanning motor movement.

The NUC integrated into the system to control system operation ,data acquisition, and analyze , so the spatial dimension is collected through the scanning motor movement.
GaiaSky camera connects with DJ UAV, user only need control the UAV by controller fly to the test area and specific height, then the UAV receive the trigger signal from the operator, the system will work and save data to the internal NUC , when finish capture the first point so the UAV can automatically fly to next position which user set before fly until finish the last position collect.

GaiaSky System Apply:
There are many applications which can take advantage of hyperspectral imaging.
 Environmental: water quality monitoring, atmospheric monitoring of the Marine environment
 Agricultural: plant disease feature classification agricultural census
 Military: anti-camouflage
 Geological research: mineral exploration, basic geological survey, soil quality survey
Agricultural:
The application of hyperspectral in agricultural field is the most extensive and a relatively mature.It has a wide and far-reaching application prospect in the detection of crop growth classification diseases and insect pests and the investigation of forestry resources.The spectral characteristics of vegetation mainly depend on the chlorophyll content and composition in the leaves. Normally growing plants have typical spectral shapes.

Environmental:
The environment is becoming more and more prominent in modern society, but the traditional environmental monitoring methods cannot get the results quickly and in real time and the process is complicated.The spectral technology can effectively identify the sediment content and pollution concentration of water body and has unique effect on the investigation and monitoring of environmental problems.
 


Military:
In the military field is mainly in the near infrared and infrared spectral band.Gaiasky-mini2-VN is very good at detecting camouflage.

Geological research
Rock and mineral geological structure identification is an important application field of imaging hyperspectral system in geological exploration.Hyperspectral imaging technology also provides more abundant data for land survey and evaluation, which is of great significance to the management of land resource.
