Title: Device and method for judging quality of construction surface
Inventor: SCHWARTZ PETER
IPC: G01B17/02
Filed: 2000-03-03
Abstract: PROBLEM TO BE SOLVED: To achieve quantitative evaluation for reproducing the quality of a covered surface, especially a construction surface with a compact and simple device by evaluating reflection light from a surface to be measured and deriving a structure variable for indicating characteristics associated with the structure of the surface. SOLUTION: The device for measuring the quality of a construction surface in an automobile or the like is provided with a lighting tube 2 and a measuring tube 10, for example, in a housing. Light being radiated from a spot light source 3 is applied to a light pattern disk 9. The disk 9 gives an influence so that light entering the surface to be illuminated shows a characteristic light pattern. Light entering an illumination surface 8 via a lens 5 enters a sensor 13 of the measuring tube 10. The device is operated by a specific control means and obtained structure characteristic value and the characteristic outer shape parameters are displayed on a display or the like.  Also, a two-dimensional CCD chip is used as a sensor to obtain the two-dimensional image of a measurement surface, and the statistical distribution of outer shape characteristics is evaluated over the measurement surface, thus evaluating structure variables or the like for the quality of the surface.
