Academic suite

• An academic suite is a part of academy providing several unique features for its researchers in their common interest of science.
• The question was: How would we define these unique features in our case of "HUT Institute of Photogrammetry and Remote Sensing"?
• The unique features may consist of the following basic elements
1. Theory of 3-D scene reconstruction
• functional model
• transformation procedure
2. People
• deep insight to the science
• illusions
• unpredictable results
• experience
• interdisciplinary contacts
• international reputation
3. Knowledge
• information production
• internal projects
• learning by researching
• external projects
• relevance
• internal workshops
• international working groups
4. Infrastructure
• hardware
• actual instrumentation
• gallery for history
• software
• organization
• information
• available documents

Functional  model

• The model is used for describing the algorithmic relationships (methods) within the 3-D scene reconstruction as developed or implemented by us (internal projects).
• The driving of the model requires individual illusions.
• It will be controlled by the theory and the experiences (user reply and internal feedback).
• The knowledge can be validated by real examples.
• Final completion usually awaits external project funding.

Scene reconstruction

• We may define our field of science as "scene reconstruction"
• Our scientific interest is concentrated to the part of information science, where the transformations between the 2-D and 3-D representations are discussed. It also covers the modeling of other phenomena, which affect or limit the reconstruction process (sensors, environment).
• The principal input data consist of images whereas the output is the scene and its visual products. In case of dynamic reconstruction the actual scene information is used for controlling further processing phases (adaptivity).
• The image data may consist of  image coordinates, but also of range or radiometric data, or attribute information, or of any other geometrically ordered previous information like maps.
• The datum or reference systems (e.g. 3-D coordinate system) are necessary when combining different kinds of data along each reconstruction process.
• The knowledge of  the behaviour of uncertainties (error propagation) caused by each individual data acquisition phase is for us important (calibration).
