Introduction: The GaiaSky-mini hyperspectral imaging system is a cost-effective airborne hyperspectral imaging system developed for small rotor drones. The GaiaSky-mini hyperspectral imaging system successfully overcomes the problem of poor image quality due to the vibration of the UAV system when the small UAV system is equipped with a push-broom hyperspectral camera with a built-in scanning system and a stabilization system. . The GaiaSky-mini hyperspectral imaging system lays the foundation for the wide application of hyperspectral imaging technology in military fields such as target recognition, camouflage and anti-camouflage, ground objects and water body telemetry, and modern precision agriculture. Features: 1. Can be mounted on a light rotor drone, extremely low system cost and test cost 2. Adopt hover shooting mode, no need for high-precision inertial navigation system, real-time image stitching 3. Easy to operate, no need for professional drone control hands, can achieve single operation 4. Image real-time return, monitor shooting effect 5. Auxiliary viewfinder camera to achieve true WYSIWYG 6. Data preview and correction function: radiance correction, reflectance correction, area correction support batch processing 7. Data format is compatible with third-party data analysis software such as Evince and Envi. 8. Support Win7-32 bit or 64 bit system 9. Automatic scanning speed matching, automatic exposure 10. Auto Exposure: Perform exposure test according to the current lighting environment to obtain accurate exposure time. While getting the best signal-to-noise ratio, it can avoid over-exposure and invalidate the data. At the same time, the software has real-time overexposure monitoring. 11. Automatic scanning speed matching: According to the current exposure time and other parameters, test shooting, get the real-time frame rate, and then calculate the appropriate scanning speed. Thereby avoiding deformation (stretching or compression) of the scanned image Introduction: Spectral range: 400-1000 (nm) Spectral resolution (30um): 4nm+-0.5nm Numerical aperture: F/2.8 Effective slit length: 8.9 (mm) Total efficiency: >50% Sensor: CCD Sony ICX285, progressive scan Full-scale pixels: 1392 (space dimension) x 1040 (spectral dimension) Pixel pitch: 6.45 (um) Camera output: 16 (bit) Connection method: USB 2.0 Power consumption: about 2.5w Working voltage: 5V Recording method: Hover (built-in scan) Equipped with platforms: Rotorcraft, unmanned airships, unmanned helicopters, etc. Recommended: Dajiang S1000 Flying height: <1000 meters (depending on the safe flying height of the drone) Lens: 18.5, 23mm (optional) Horizontal viewing angle (FOVac, °): 27@18.5mm, 21@23mm Horizontal field of view: 234 meters @18.5mm, 186 meters @23mm (flight altitude 500 meters) Scanning field of view (°): 33.5@18.5mm, 26@23mm Bin mode: 1X 2X (recommended) 4X Spatial resolution (@23mm, height 500m): 0.17m@18.5 0.14m@23mm 0.34m@18.5 0.27m@23mm 0.67m@18.5 0.53m@23mm Scanning speed (line images/s) : 30 60 84 Single shooting speed (seconds): 60 15 7 Weight: camera (with built-in scanning) 1.3Kg Stabilizing the gimbal: 1.7kg Data acquisition and controller and: 0.65kg Battery: 0.25kg Total weight <4kg Battery: 14.8V 2200mAh (working time > 2 hours) 103*31*35(+-1mm) PTZ and camera installation space: >=330 (suspended height) *200*260mm
