Abstract

An investigation is presented of a low cost approach to the measurement of two and three dimensional objects using a flatbed scanner and image analysis software. Conventional measurement using relatively low cost instruments such as micrometers and vernier callipers can be time consuming and requires operator skills which result in higher overall costs. The increasing resolution and decreasing prices of flatbed scanners introduces the possibility of their use as a low cost alternative to traditional manual measuring. To investigate this, a simple dimensional measurement technique was developed using an unmodified, then a modified, flatbed scanner, a standard PC, and software. A dimensional accuracy of ±0.05 mm was achieved with a modified flatbed scanner system for slip gauge samples of nominal thickness 10mm and 5mm.
