description L'invention concerne un système et un procédé d'inspection à haute vitesse d'objets (22) ayant des surfaces délimitées. L'appareil (46) traite l'image de l'objet inspecté en fournissant une première image traitée comprenant le module d'intensité de la lumière émise par l'objet inspecté, et une deuxième image modifiée comprenant pour chaque point de l'image l'angle du gradient d'intensité de lumière le plus élevé à ce point de l'image. La variabilité de l'angle dans l'ensemble de l'image est ensuite déterminé (48), le module et la variabilité sont combinés, par multiplication par exemple, afin de fournir des données sur l'image comprenant une évaluation quantitative de l'image. Ces données peuvent être à leur tour combinées pour donner une seule mesure quantitative indicatrice des caractéristiques voulues de l'objet inspecté, ou utilisées pour déterminer des caractéristiques de la surface, localiser des irrégularités de la surface et/ou déterminer les dimensions, la forme, l'orientation, etc, des contours ou d'une partie de l'objet, comme voulu. An inspection system and method suitable for high speed inspection of articles having bounded surfaces are disclosed. The apparatus processes the image of the item being inspected to provide a first processed image comprising the modulus of the light intensity from the article being inspected, and a second modified image comprising, for each point, the angle of the highest light intensity gradient at that point in the image. The variability of the angle throughout the image is then determined, and the modulus and variability combined such as, by way of example, by point by point multiplication, to provide image data comprising a quantitative evaluation of the image. This data in turn may be combined into a single quantitative measure indicating the desired characteristics of the article being inspected for acceptance and rejection, or otherwise used to determine surface characteristics, locate known or unknown surface anomalies, and/or determine the size, shape, orientation, etc. of an outline or a portion thereof, as desired. The determination and use of the variability of the angle, either alone or in conjunction with the modulus highlights the boundaries of the object for emphasis or de-emphasis, as desired, as angle variability in the region of a boundary is normally very low. Also, other uses of the variability of the angle or other angle dependent information alone or with the modulus avoids the use of matrix
