摘要： An apparatus and method for measuring a three-dimensional shape of an object using a projection moiré device. The method comprises the steps of obtaining a grid pattern image projected on a reference plane of a moving table and applying a buckets algorithm thereto, thereby achieving a reference phase, obtaining a grid pattern image projected on the object set on the moving table and applying a buckets algorithm thereto, thereby achieving an object phase, calculating a difference phase between the object phase and the reference phase, thereby achieving a moiré phase, and unwrapping the moiré phase, thereby achieving a level information of the object. The apparatus and method measure the three-dimensional shape using a projection grid without a reference grid, thereby achieving compactness of equipment, simplicity in usage and manufacturing cost reduction.

摘要： The present invention relates a moiré image capturing apparatus and the related method, the apparatus comprising: an optical projection unit arranged in perpendicular to a reference surface with a light source for illuminating light to the reference surface, where an object is positioned, and a projection grating installed on a optic axis between the light source and the reference surface for projecting the light generated by the light source toward the object; and an optical imaging unit arranged in perpendicular to the reference surface with an imaging lens for making an image with the light reflected at the object and a light receiving part installed on the same optic axis as that of imaging lens for receiving the light passing through the imaging lens to turn into a moiré image, so that a reference grating is removed to make the apparatus in a simpler structure and that a step of removing an image of the reference grating except the moire image having information on figure of the object is not included in the method for capturing the moire image, thereby making a moire image capturing apparatus cheaper in a simpler structure.
