摘要： A device for measuring three dimensional shape is configured to perform one of a first imaging operation as imaging processing of a single operation among a multiplicity of imaging operations performed by irradiation of a first light pattern of multiply varied phases, and a second imaging operation as imaging processing of a single operation among a multiplicity of imaging operations performed by irradiation of a second light pattern of multiply varied phases. The device is configured to, simultaneous with completion of the first or second imaging operation, start shifting or switching operation of said first grating or a second grating relating to said first imaging operation. The device is configured to, without waiting for completion of the shifting or switching operation, perform the other imaging operation from among the first and second imaging operations.

摘要： A three-dimensional measuring device includes an irradiation device configured to irradiate and switch among a multiplicity of light patterns having different periods and having a striped light intensity distribution on at least a measurement object, a camera having an imaging element capable of imaging reflected light from the measurement object irradiated by the light pattern, a rack configured to cause relative change in positional relationship between the imaging element and the measurement object, and a control device configured to perform three-dimensional measurements based on image data imaged by the camera. The control device performs the three-dimensional measurements by performing a phase shift method calculation of height data as a first height data for each pixel unit of image data based on a multiply phase-shifted image data obtained by irradiating on a first position a multiply phase-shifted first light pattern having a first period.

摘要： There is provided a method of evaluating quantitatively surface properties such as cleanness and quality of the surface of a work that has been evaluated in the past by visual appearance inspection. A determined pattern 14 is made from plural concentric circles arranged at a center of an object lens in a taking picture device 12. A front edge of a probe is in contact with the surface of a work by the probe 10 that is provided at a middle portion of a cylindrical case 11 in a vertical direction so that the surface of the work and the determined pattern face each other. The determined pattern is illuminated by light of a light source so that a reflected image of the determined pattern is projected onto the surface of the work. A picture of the reflected image is taken by the taking picture device. The resulted image data includes standard deviation of brightness distribution of the resulted image data positioned on radius lines extending in all directions to outside from a center of the ring pattern image. A relative value between the resulted standard deviation and the standard deviation of the amplitude of the brightness distribution of the image data on a plurality of lines of the criteria mirror surface is determined as the mirror index. The image clarity of the surface of the work is evaluated from the mirror index of the plurality of lines.
