| Title of the article | The use of electronic photography and computer graphics in AutoCAD in strain measurement of awning materials |
| Abstract. | This article describes the results of the development of non-contact strain measurement techniques used by the authors in the study of their formative properties. There are some of the ways to measure the deformation of similar materials in related industries. The need for different method of measurement explained. Algorithm and test results are presented. The technique developed by the authors includes two main stages. The first stage – the making images of the sample, the second – processing the pictures on the computer program AutoCAD. The resulting sample photos in JPEG format imported into AutoCAD for further processing. Images on a pre-known value (basis) ware calibrated. By using some of the tools in AutoCAD observable quantities have been measured. Presented comparison of the results of measurements made with the help of the developed methodology with the results of the contact methods of measurement. Contact method of measurement is taken by measuring observable quantities by an electronic caliper. We analyze the accuracy of the proposed method of measurement. Drawings and tables with the result of this investigation was submitted. |
