Abstract:
A method for detecting a defect on a surface ( 12 ) by multidirectional lighting includes acquiring a plurality of images of the surface ( 12 ) using an optical device ( 14 ) having an optical axis, each image being acquired with a lighting of the surface along a lighting direction (E, E′) given for each point of the surface ( 12 ) and an optical direction (O), the images being acquired with different lighting directions (E, E′) or different combinations and/or with different optical directions (O); for each point, calculating a plurality of parameters, the parameters including coefficients of an equation characterizing the response of said point of the surface as a function of the lighting direction (E, E′) and an observation direction (B, B′); and deducing from the calculated parameters whether the surface ( 12 ) has a defect at said point.

Claim (Index 26):
A device for detecting a defect on a surface, the detection device including:\n an optical device having an optical axis, the optical device being configured to acquire an image of the surface along a given optical direction; a lighting device having several different lighting direction; and an electronic calculating device, the electronic calculating device being configured to:\n acquire a plurality of images of the surface via the optical device, each image being acquired along the given optical direction with different lighting directions or different combinations of lighting directions for each image, \n for each point of the surface, calculate, from acquired images, a plurality of parameters, the parameters including coefficients of an equation characterizing the response of the point of the surface as a function of the lighting direction and an observation direction; and \n deduce from the calculated parameters whether the surface has a defect at the point.
