Faglig innhold

The first module of the course introduces cameras, visual and infrared spectrum imagers, imaging spectroscopy both theoretically and practically. It contains a review of basic optics to explain the design of a hyperspectral imager. This includes fundamental effects such as refraction, diffraction and interference. With the basic theory established, concepts like spectral range, bandpass, etendue and throughput will be explained. Calibration and correction will be emphasized: Spectral, radiometric, geometric including keystone/smile, and calibration in the field. The second module considers how to design a drone based optical remote sensing system for high quality measurements: Drone based sensor systems, system design, metadata, time synchronization, navigation and geolocation, data compression, onboard and real-time processing systems. Mechanical, electric and software image stabilization, attitude control, gimbals. Methods and software for orthophoto and photogrammetry. The third module gives an introduction to practical drone operations, emphasizing mission planning, risk analysis and safety assurance. The fourth module addresses general challenges in remote sensing with regards to the radiometric effects of the atmosphere and how to compensate for this: Atmospheric effects on remote sensing, Radiative transfer equation, two stream equation, discrete ordinate method, phase functions, application to remote sensing, radiative transfer numerical modelling, spectral properties of targets. The fifth module addresses satellite remote sensing systems. Orbits, attitude control, image acquisition, mission design, mission analysis, correction. The course will give practical training on laboratory calibration, use of cameras and hyperspectral imagers from moving and fixed platforms. The data collected will be evaluated and summarized in a mandatory project report.

Læringsutbytte

Knowledge: The main learning objective is to understand the basic principles of remote sensing from space and air using optical instruments in visual and infrared spectrum including RGB cameras, multispectral and hyperspectral instruments. Skills: Analysis and design of optical imaging systems. Calibration of optical instruments. Planning and execution of drone operations for remote sensing. Use of software for orthophoto and photogrammetry. General competence: The aim is to enable the students to conduct and develop payload systems and experiments utilizing optical imaging as a tool in remote sensing.

Læringsformer og aktiviteter

The course is given as a mixture of lectures, assignments, and a project that is based on laboratory and field experiments.

Mer om vurdering

Prosjektet vil telle 50% på karakteren, og skriftlig eksamen vil telle 50%.

Ved utsatt eksamen kan skriftlig eksamen bli endret til muntlig eksamen.

Kontinuasjon og frivillig gjentak/forbedring kan gjennomføres for enkelte delvurderinger uten at alle delvurderinger må tas opp igjen.
