This work deals with performance verification of a low cost laser scanner with a granite square gauge. This gauge has well finished surfaces and dimensional precision, enough for verification of a low cost laser scanner. The square was initially measured with the scanner and a cloud of points was saved in a file. A filtering method was applied to extract noise from data and the flatness deviation of each plane, together with the angle between planes, were determined. MatLab software was used as a tool to determine the deviations and angles. Analysis of normality of data was carried out with normal probability plot graphs. Results were compared and were below from scanner manufacturer ones. It was observed that deviations were above stated in manufacturer manual.
Key words: laser scanner / performance / square gauge
