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