72878 - Applied Photogrammetry M

Course Unit Page

Academic Year 2018/2019

Learning outcomes

The course provides the knowledge necessary for planning and executing, by photogrammetric techniques and/or laserscanning, 3D surveys and representation of buildings and infrastructures, monuments, urban centres and cities. Some aspects related to non-cartographic applications are discussed, principally in the field of Cultural Heritage, together with the integration with other Geomatic techniques.

Course contents

Photogrammetry, laserscanning and the other surveying techniques in Geomatics. Remarks on the historical development. 

Coordinate systems in photogrammetry. Central projection and Projective transformation: basic mathematical remarks, collinearity equations. The "normal case" in stereopair processing. 

Photographic equipment and techniques (analogic and digital systems), color theory. Geometrical and radiometrical characteristics for digital acquisition, digital images, image processing and analysis. Metric and semi-metric film-based cameras. Aerial and terrestrial digital cameras. GPS-IMU systems for direct orientation. 

The orientation procedures. 

Interior orientation for a film based and for a digital camera. The calibration of non metric digital cameras: techniques and algorithmic approaches. 

Exterior orientation: of a single image, of a stereopair in two stages, of a stereopair in a single stage. The survey of the Ground Control Points. The Photogrammetric Triangulation by independent models and by bundle block adjustment. 

The main components of a plotting analytic instrument, digital photogrammetric workstations. Stereoscopic and monoscopic plotting, specific solutions provided by digital photogrammetric workstations. 

Digital image matching and different strategies for 3D model reconstruction, automatic processing of the photogrammetric stages. Digital Terrain Models (DTM), Digital Surface Models (DSM) and derived products. 

Rectification  of digital images. 

Planning and realization of a survey: the aerial case and the terrestrial one. The survey of buildings and monuments with complex geometrical properties. Different hardware/software configurations for close-range surveying (architecture, civil engineering, archaeology, industry, etc.) 

Terrestrial Laser scanning as a complementary technique for 3D surveying in building, architectural and industrial applications: from data acquisition to visualization of point clouds, generation of the mesh and derived products. 

Terrestrial laserscanning instruments and data processing software. 

Integration of photogrammetric and laser data with other products (multispectral remote sensing, mobile mapping systems, GIS, diagnostic technologies for Cultural Heritage surveying and monitoring).

Teaching methods

Lectures and exercises in Laboratory and on the field. 

Analysis and discussion by examples of real cases.

Assessment methods

The examination at the end of the course is in written form with eventual oral integration, and aims to assess the achievement of learning objectives. To obtain a passing grade, students are required to demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical Language.

Teaching tools

The most significant part of the course is designed to practical activities on the field and in the laboratory, by means of commercial, scientific and open source programs.
