The course provides basic concepts in design and completion of photogrammetric and laser scanning surveys.
Analytical photogrammetry. Collinearity condition. Projective transformation and image metrology. Interior and exterior orientation. Rotation matrices. Collinearity equations. Object space and image space transformations. Error theory of the normal case. Planar object projection: homographies and image rectification. Exterior orientation: direct and indirect methodologies. Complanarity equations. Relative and absolute orientation. Bundle block adjustment and block adjustment by independent models.
Acquisitions sensors and systems. Lenses and image formation. Films and Charged Coupled Devices (CCD). Spatial and radiometric resolution. Image distortions. Film and digital cameras (metric, semi-metric and consumer cameras). Scanners. Calibration techniques. Image space corrections: radial and tangential distortion, film unflatness, atmospheric refraction. Airborne and terrestrial laser scanners. Georefencing.
Design, acquisition, georeferencing and bundle block adjustment of photogrammetric surveys. Flight planning. Direct georeferencing using GPS and INS. Simulations and block adjustment.
Photogrammetric instruments and measuring techniques. Stereovison and stereorestitution. Stereo and mono-comparators. Stereoplotters. Digital map production and GIS data acquisition. Analogue, analytical and digital stereoplotters. Measurement operations: points, contour levels, gridded and irregularly triangulated DTM.
Digital photogrammetry. Image processing: filtering, convoluting and restoring a digital image. Digital image correlation. Feature extraction. DTM production through automatic image correlation. Multiresolution techniques: image pyramids.
Photogrammetric products. Image rectification and its accuracy. Rectification by differential transofrmation. Orthophotography.
Design and quality control in map production.
Oral examination with discussion of the project completed in the exercises.
