Transformations play a special role in photogrammetry, so learning the mathematical principles and their calculations helps us better understand and employ photogrammetry tools. A mapping performs the task of transferring…

A rotation matrix is ​​able to transform a point or a vector in space in proportion to the rotations values expressed in radian. Every single position of a static object…

Minimum-constraint BBA: Bundle Block Adjustment (BBA) is a relatively complex optimization process with many small details. One of the most important aspects of BBA is choosing a coordinate system. Definition…

Finding common points between images is a necessary task in photogrammetry. It involves finding 2D image points and putting common labels on them. Nowadays, there are lots of automatic approaches…

Every photogrammetric data processing begins with data collection. Sensor and data are the most vital part of any project, usually the specification of a sensor is known at least to…
