  • Patent number: 11248903
    Abstract: A three-dimension measurement device includes a moving device, a projecting device, a surface-type image-capturing device and a processing device. The moving device carries an object, and moves the object to a plurality of positions. The projecting device generates a first light to the object. The surface-type image-capturing device senses a second light generated by the object in response to the first light to generate a phase image on each of the positions. The processing device is coupled to the surface-type image-capturing device and receives the phase images. The processing device performs a region-of-interest (ROI) operation for the phase images to generate a plurality of ROI images. The processing device performs a multi-step phase-shifting operation for the ROI images to calculate the surface height distribution of the object.
