STUDY OF AMBIENT LIGHT INFLUENCE ON LASER 3D SCANNING
The quality of 3D scanned data is influenced by many factors, such as scanned surface colour, glossiness, geometry, ambient light, scanner resolution, proper selection of scanned segments, etc. Ambient light is important source of errors, especially for scanners that are based on projected patterns and structured lighting. The laser 3D scanners are also influenced by ambient light, and this paper studies the effects of ambient light on a specific commercial scanner. Preparatory phase of digitising process includes selecting proper combination of scanner’s sensor aperture and shutter time, depending on the characteristics of scanned surface. This paper investigates a relationship between the ambient light intensity, the colour of scanned surface, and the laser scanning quality.
