摘要： A surface state inspection apparatus has a lighting device that irradiates an inspection target placed on a stage with light, an imaging device that images the inspection target, and a detection device that detects a surface defect of the inspection target by analyzing a first inspection image obtained by the imaging device. The lighting device is a surface light source that includes a light emission region having a predetermined size and, in the lighting device, portions of light emitted from positions in the light emission region differ from each other in a spectral distribution. The detection device detects a portion in which a hue is different from that of its surrounding portion in the inspection target surface as a flaw. The detection device detects a portion in which the hue is substantially equal to that of its surrounding portion while brightness is different from that of its surrounding portion as a stain.

摘要： The shape measurement apparatus calculates a characteristic amount for a plurality of points of interest on a surface of a measurement target object, based on an image obtained by image capturing with a camera, calculates an orientation of a normal line based on a value of the characteristic amount by referencing data stored in advance in a storage device, and restores the three-dimensional shape of the surface of the measurement target object based on a result of the calculation. The storage device stores a plurality of data sets generated respectively for a plurality of reference positions arranged in a field of view of the camera, and the data set to be referenced is switched depending on a position of a point of interest.
