The DOM Generation and Precise Radiometric Calibration of a UAV-Mounted Miniature Snapshot Hyperspectral Imager
Hyperspectral remote sensing is used in precision agriculture to remotely and quickly acquire crop phenotype information. This paper describes the generation of a digital orthophoto map (DOM) and radiometric calibration for images taken by a miniaturized snapshot hyperspectral camera mounted on a lightweight unmanned aerial vehicle (UAV). The snapshot camera is a relatively new type of hyperspe...
متن کاملMeris In-flight Spectral Calibration
This paper first describes the different activities conducted for MERIS regarding it’s spectral calibration. The onboard spectral calibration is based on the use of a panel which presents well defined absorption peaks. In this absorption bands, each MERIS detector is characterized in wavelength. Limitations of this method are in the near infra red because of the lack of absorption lines in the ...
متن کاملOcean PHILLS hyperspectral imager: design, characterization, and calibration.
The Ocean Portable Hyperspectral Imager for Low-Light Spectroscopy (Ocean PHILLS) is a hyperspectral imager specifically designed for imaging the coastal ocean. It uses a thinned, backsideilluminated CCD for high sensitivity and an all-reflective spectrograph with a convex grating in an Offner configuration to produce a nearly distortionfree image. The sensor, which was constructed entirely fro...
متن کامل3D Classification of Urban Features Based on Integration of Structural and Spectral Information from UAV Imagery
Three-dimensional classification of urban features is one of the important tools for urban management and the basis of many analyzes in photogrammetry and remote sensing. Therefore, it is applied in many applications such as planning, urban management and disaster management. In this study, dense point clouds extracted from dense image matching is applied for classification in urban areas. Appl...
متن کاملSpectral and Radiometric calibration of the Advanced Land Imager
Calibration of spectral and radiometric measurements of the Advanced Land Imager (ALI) is a critical element of its land-sensing mission. Without initial ground-based and subsequent on-orbit standardization, the data cannot be reliably used for the intricate analysis of atmospheric conditions and complex surface regions. Daily, weekly, and monthly recertification steps are taken to recalibrate ...
