Overview
• Photogrammetry: Definition and applications
• Photogrammetric tools:
– Rotation matrices
– Photogrammetric orientation: interior and exterior
orientation
– Collinearity equations/conditions
• Photogrammetric bundle adjustment
– Structure of the design and normal matrices
• Special cases:
– Resection, intersection, and stereo-pair orientation

Photogrammetry
• Classical Definitions:
– The art and science of determining the position and
shape of objects from photography
– The process of reconstructing objects without touching
them
– Non-contact positioning method
• Contemporary Definition:
– The art and science of tool development for automatic
generation of spatial and descriptive information from
multi-sensory data and/or systems

+ accurate lab calibration + low-cost/off-the-shelf
+ large image format + easy to integrate with other systems on
+ low distortion lens system the same platform (e.g., LiDAR)
+ stable IOP + convenient for small area coverage &
+ extremely-high geometric image UAV systems
quality - should be calibrated by the end user
- high initial procurement cost - inferior geometric quality and lens
- not easy to integrate with other system
systems on the same platform - stability of IOP is not guaranteed
(e.g., LiDAR) - limited array size
