Our 3D laser scanner develops color images that are as detailed as high-resolution digital pictures. T pictures. The individual scanned images are ‘stitched’ together to form a full color 3D model of the compartment that can be used to obtain measurements. The scanned images are typically accurate to within a fraction of an inch.” – David W. Larsen, PE, Director of Engineering of Engineering at Glosten
