Welcome to the Image-Based 3D Modeling blog. If you started reading this blog it is likely that you are interested in creating 3D models from images for various purposes.
The blog is aimed at everyone (professionals and non professional) who wish to understand and apply the basic concepts of Photogrammetry. Professionals like surveyors, architects, engineers, heritage officers, archaeologists, conservation architects and many others still using 2D representations of 3D objects may be asking themselves the following question: Why do I need fully textured 3D models when all I want is a simple plan or elevation drawing? And why using images?
Well, fair enough! If you only have to draw that much. But what if you have to produce 3 plans, 4 sections, 3 elevations and in addition to that you are required to show in detail the condition of a damaged brick wall, several decorated architectural details like capitals or even a statue?
Why taking images? Because they are an inexpensive and a rich data acquisition method from which you can extract both regular geometric shapes (e.i. a rectangular wall), free-form surfaces (e.i a statue) and color information.
The posts of this blog will cover all the different steps of the photogrammetric pipeline in a very simple and practical way with lots of external references to more detailed tutorials on the use of the various software and other published documentation. The blog is focused on the representation of real 3D object like a house, a monument or an archaeological find where the 3D model is based on real measurements (Reality-Based 3D models).
See you soon for some real stuff….
