Abstract: Provided are an apparatus and a method for measuring a three dimensional shape with improved accuracy. The apparatus includes a stage, at least one lighting unit, a plurality of image pickup units and a control unit. The stage supports an object to be measured. The lighting unit includes a light source and a grid, and radiates grid-patterned light to the object to be measured. The image pickup units capture, in different directions, grid images reflected from the object to be measured. The control unit calculates a three dimensional shape of the object from the grid images captured by the image pickup units. The present invention has advantages in capturing grid images through a main image pickup portion and sub-image pickup portions, enabling the measurement of the three dimensional shape of the object in a rapid and accurate manner.

Abstract: The present invention relates to a three-dimensional image measuring apparatus comprising: an XYZ shaft transfer means mounted onto a base member; a work stage mounted to the base member, for moving a measuring object to a measuring position and thereafter supporting it and having a predetermined reference surface set at a side thereof; an image obtaining means in which it is moved toward X,Y and Z shafts by the XYZ shaft transfer means, scans a grating image by the frequency of N times to a side of the measuring object supported and fixed to the work stage, obtains the changed grating image by the measuring object by N times; a light emitting means mounted to a side of the image obtaining means for generating and emitting light with a predetermined wavelength; and a control unit which irradiates light generated from the light emitting means mounted to a side of the image obtaining means to the reference surface set the side of the work stage, receives the changed grating image obtained from the image obtaini

Abstract: A three dimensional shape measurement apparatus includes an illumination section and a grating transfer unit. The illumination section includes a light source unit generating a light and a grating unit changing the light generated by the light source unit into a grating pattern light having a grating pattern. The illumination section illuminates the grating pattern light onto a measurement target in a predetermined direction. The grating transfer unit transfers the grating unit in a predetermined inclination direction with respect to an extension direction of the grating pattern and an arrangement direction of the grating pattern. Thus, manufacturing cost may be reduced, and the three dimensional shape measurement apparatus may be easily managed.

Abstract: A 3D shape measuring apparatus using a shadow moire, which can measure a 3D shape of a test object by selectively switching on/off a plurality of illuminating parts irrespective of a form of the test object is provided.

Abstract: An apparatus for measuring a 3-dimensional (3D) shape which can remove a shadow, which may occur when measuring the 3D shape, and also can measure a reflected light from an external surface of a test object, is provided. The apparatus for measuring a 3D shape includes a projection part 10 generating a light, an image formation part 20 sensing the light, a prism part 30 being provided between the projection part 10 and the viewing part 20, and a first mirror part 40 and a second mirror part 50 being provided in both ends of the prism part 30. Also, the prism part 30 selectively transmits the light generated from the projection part 10 to the first mirror part 40 and the second mirror part 50 to be directed towards an external surface of a test object 1. When the light reflected from the external surface of the test object 1 is selectively transmitted to the first mirror part 40 and the second mirror part 50 and thereby reflected, the prism part 30 transmits the reflected light to the viewing part 20.
