Digital Photogrammetric Systems


Credit Hours:


Learning Objective:

Understand the fundamentals of digital photogrammetry. Be able to mathematically relate ground and image coordinates. Be able to rectify and orthorectify a frame image to a reference coordinate system. Understand and carry out a task to build a 3D model from stereo images. Appreciate other related photogrammetric algorithms, operations, and products.


Reconstruction of 3D objects and terrain from digital imagery taken with conventional frame cameras. Photogrammetric data as input for CAD and VR databases. Digital camera architecture and implications for photogrammetry. Modeling and estimation of camera geometry; basic least squares. Interior orientation, exterior orientation, relative orientation, absolute orientation. Coordinate systems, coordinate rotations, image resection and bundle block adjustment. Rectification and orthorectification of vertical and oblique imagery. Aerial, terrestrial, and space platforms for image acquisition; flight and mission planning. Stereo processing for 3D data acquisition, pairwise rectification for stereo viewing. Commercial applications for mapping and data extraction. Accuracy standards and error propagation. Interface with GIS software and data formats. Automation of the data collection process, image matching, DEM generation. Basic image processing: histogram modification, resampling, filtering. TIN processing: data structures, generation, exploitation. Synthetic image creation from object models with texture projection; animations and fly-throughs.
