Analytical Camera Model Supplemented With Influence of Temperature Variations

A camera in the building site is exposed to different weather conditions. Differences between images of the same scene captured with the same camera arise also due to temperature variations. The influence of temperature changes on camera parameters were modelled and integrated into existing analytical camera model. Modified camera model enables quantitatively assessing the influence of temperature variations. An application for real-time activity tracking on the building site was developed as a pilot project. The differences between as-planed and as-build are recognized automatically from building site images. Concept is based on comparison between real-time captured images and 4D model, made by 4D tool.
