Abstract: 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.

Abstract: A three-dimensional measurement apparatus includes a plurality of cameras, a normal calculation unit for obtaining from respective captured images a normal direction serving as a physical feature of a surface of a measurement object, and a corresponding point calculation unit for retrieving corresponding pixels of the images using the physical feature. Using the apparatus, a three-dimensional measurement can be performed on a basis of a parallax between the corresponding pixels. Also, the apparatus transforms the normal direction of each image into a common coordinate system. A parameter of the coordinate transformation may be calculated from a parameter obtained during a camera calibration. This three-dimensional measurement apparatus can measure a three-dimensional shape of a mirror surface object precisely without being affected by differences in positions and characteristics of the cameras.
