This site is primarily geared around my work with photogrammetry, although naturally it also contains information about the work that I do with mapping, surveying and 3D modelling. All these subjects being closely bound together as a core theme – well for me at least. My background in statistics, signal processing, and scientific computing underpins it all.

The objective of the photogrammetric process is to produce a 3D model from which measurements can be made. The model is created from two or more photographic images of a target scene or object using a calibrated camera. The images are taken from a number of different positions around the target and "tied" together by the modelling process using a set of common control points. From the generated model it is then possible to accurately estimate three dimensional coordinates of various points of interest in the image set.

Photogrammetry has many applications such as in surveying, map making, data acquisition, forensics, archaeology, history and more. Generally, if it is possible to take a series of photographs of a target, then it is possible to make accurate measurements from them.
Please spend some time looking at some of my examples that show photogrammetry in operation on real projects. I intend to update the examples on a regular basis, just as soon as completed project work becomes available.
If you would like to know more about how photogrammetry may be deployed on your particular project, or if you would like to commission me, or indeed have any other queries, then please use the contact form.
