Abstract

An apparatus for detecting surface characteristics on food objects conveyed by a conveyor, has a first imaging device for capturing two-dimensional image data (2D) and a second imaging device for capturing three-dimensional image data (3D) of a food object. At least one image processing unit is configured to utilize either one of the 2D or the 3D image data in determining whether a potential defect is present on the surface of the food object. In case such a potential defect property is found, the image processing unit determines a surface position of the potential defect, and utilizes the remaining one of the 2D or the 3D image data in determining whether an actual defect is present on the surface of the food object at the indicated surface position. Further, the apparatus has an output unit for outputting defect related data in case both of the 2D and the 3D image data indicate that an actual defect is present on the surface of the food object at the indicated surface position.
