An apparatus and a method for measuring a three-dimensional shape are disclosed. The apparatus includes a transfer stage, a first projector, a second projector, a camera unit and a control unit. The transfer stage transfers a measurement object to a measurement position. The first projector irradiates a first pattern light having a first equivalent wavelength toward the measurement object in a first direction. The second projector irradiates a second pattern light having a second equivalent wavelength that is different from the first equivalent wavelength toward the measurement object in a second direction. The camera unit takes a first pattern image that is generated when the first pattern light is reflected by the measurement object, and a second pattern image that is generated when the second pattern light is reflected by the measurement object. The control unit controls the first projector and the second projector, and obtains a three-dimensional shape of the measurement object through the first pattern image and the second pattern image. |
