Polygon model scanner is developed to reconstruct a three-dimension image of an object�s surface. Amongst is by installing five infrared sensors in the sensor array as a medium to harvest data. All components used in the device then are installed in a closed box to avoid any source of light. Next is ellipse, hemisphere, cylinder and rectangle shapes were used to be tested in the developed device. Results from the experiment showed that the device is capable to reconstruct an image of a polygon model. As a whole, it requires 60� min to scan the whole model which covers 10� cm of the height with a diameter of 5� cm. Finally, Butterworth, Mean, Median filters and point fitting were used to determine which filters gives accurate dimension compared to the reference shape. © Springer Nature Singapore Pte Ltd. 2017.
