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.

Catalog Inquiry

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.

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.

GaiaSkySystem Function:

· Auto exposure time;

· Auto match scanning speed;

· Auxiliary camera (user can observe you want );

· Data analysis (reflectance /radiometric/uniformity/lens/area /atmospheric/calibration)

· Spectra /imaging view and export;

· Spectral Angle matching;

· NDVI(advance custom);

· PCA;

· Supervised classification;

· Support lens change;

· Standard type data (support envi/envice/matlab);

· Images stitching;
