Metrology or three-dimensional contactless coordinate measurement of object surfaces by recording of a stack of 2D images using a camera to record images at different focal depths

摘要

Method for 3D contactless optical measurement of object surfaces using an optical image sensor (3) for 2D image detection. The method involves recording images at a focal plane position (Fz) in a third z direction. The depth of the focal plane is very small. A series of images is recorded to create an image stack from which the 3D image is created. An independent claim is made for a coordinate measurement device with a camera for recording 2D image sets that are combined to form a 3D image for coordinate measurement.
