Digital 3D plus color imaging is a growing field as it has many industrial applications. One of them is the precise understanding of optical properties of objects, which is possible to obtain from 3D plus brightness or color data. Those properties are usually important inspection criteria; for example, the specular sharpness of a coatted surface is usually related to the coating quality. This paper is related to a procedure for recovering the specular sharpness and other surface-related properties from objects. The current approach works on 3D plus brightness or color data, which are retrieved in two steps using a common structured-light triangulation-based technique and an ordinary non-structured spot light. Some experimental results obtained on industrial parts are also shown
