Geometrical Analysis and Rectification of Thermal Infrared Video Frame Scanner Imagery and Its Potential Applications to Topographic Mapping

[摘要] This thesis is concerned with an investigation into the possiblites of generating metric information and carrying out topographic mapping operations from thermal frame scanner video images. The main aspects discussed within the context of this thesis are:- (i) the construction and operational characteristics of video frame scanners; (ii) the geometry of frame scanners; (iii) geometric calibration of thermal video frame scanners; (iv) the devising, construction and integration of a video-based monocomparator for video image coordinate measurements; (v) devising and implementing suitable analytical photogrammetric techniques to be applied to frame scanner imagery; (vi) the use of such frame scanners to acquire airborne video images for a pre-selected test area; (vii) the interpretation of thermal video frame scanners for topographic mapping; (viii) digital rectification of frame scanner imagery; and (ix) creation of a three-dimensional stereo model on a video monitor screen using the digitally rectified video images.
