摘要:
A method for recording an image of an object includes projecting a strip pattern onto the object, recording the projected strip pattern as raw image data using a camera, and calculating an image of the object from the raw image data. A strip pattern having a duty cycle of less than 1 can be used to increase measuring precision during measurement of a translucent object, and can eliminate a need for additional contrast agents for a recording of the object.
