A three-dimensional image measuring apparatus includes a measurement platform, a movable optical head, a three-dimensional calculator module, a moving module and a calibration controlling module. The movable optical head includes a beam splitter unit, a projecting module, an image-capturing module and an indicator module. The measurement platform supports an object under measurement. The projecting module generates a structure light of parallel sinusoid strips pattern to the object under measurement. The image-capturing module includes image-capturing units facing the object under measurement from different directions or angles. Each image-capturing unit is configured to capture a reflection image which is formed from the structure light of parallel sinusoid strips pattern reflected by the object under measurement. The indicator module projects an alignment beam onto the object under measurement for forming an alignment mark. The calibration controlling module selectively drives the moving module to move the movable optical head according to the alignment mark. |
