Abstract

The invention relates to a device for the contactless detection of a three-dimensional contour, comprising a projector with an imaging element and a projection lens for depicting a stripe pattern that is generated on the imaging element in an object space. The invention further comprises a camera arrangement for the surveillance of the object space from two different directions, having two camera lenses. The projector and the camera arrangement are housed together in a measurement head that can be handheld. The invention further relates to a method for detecting a three-dimensional contour using said device.
