Abstract

The application is developed for measuring the dimensions and the three dimensional shape of soap stone bricks. The bricks are used as elements of stone ovens. Each brick is approximately 280 millimeters wide, 70 millimeters thick and the length varies from 140 up to 630 millimeters. The shape of a stone is measured by two images captured from known camera positions by comparing the images with the projected images of the floating 3D-model. The original images and the projected images from the model are fitted together by changing the shape and the position of 3D-model. An unknown stone can be measured by finding the optimal shape and the position of the model in relation to the original image data of that stone. In other words, the synthetic stone is moving, rotating, and reshaping between two fixed cameras, looking for the best fit to the original image data.
