Precedent Study 5


Study 5 - Data Generation for CAAD with Digital Photogrammetry - Horst A. Breyer, Andre Streilein


This is a paper from 1991, however still valid in terms of fundamental ideas. I thought it would be worthwhile having a good look into it to see what the motivations were then and also what was available and where it was heading.





It seems that because of the technology available, there was a lot more thought put into which photographs to take and how many to take. The position of the cameras was all determined manually and lines were computed between points. The prcess showed potential at this point of time, and accuracy could be achieved with large well defined features. Manual and semi automatic measurements could already be achieved. Still it is unlikely today that it can be a fully automated process.
