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.

Apparatus and method for measuring a three dimensional shape

A method for measuring a three-dimensional shape includes the steps of: forming a pattern on a light irradiated to an object from a light source unit installed in an electronic device by a pattern unit installed in the electronic device; generating image data by photographing the object to which the light on which the pattern is formed is irradiated by a camera unit installed in the electronic device; generating phase data for the object using the image data, and generating, using the phase data by a data generation unit, feature value data for a feature value of the object; and determining, by a determination unit, whether the feature value data is identical to pre-stored reference value data using the feature value data and the pre-stored reference value data.

Device and method for measuring three-dimensional shape

A three dimensional (3D) measuring apparatus and method are provided. The 3D image measuring apparatus includes a stage, a projection portion, and an imaging portion. The projection portion includes first and second lights, first and second lattices, and first and second projection lenses. The imaging portion includes an imaging lens and a camera. The projection portion further includes a movement instrument which controls the first and the second lattices through a predetermined number of movement actions during operation of the measuring apparatus.
