Abstract
An apparatus and a method are presented which render possible the 3D acquisition of objects (4) with the aid of an optical 3D sensor from an angular range that is larger than that which is yielded by one view, in a short measuring time and without mechanical movement. This end is served by a specific mirror arrangement (3) in combination with a modification of the optical 3D sensor.

A method for forming a comprehensive three-dimensional measurement of an object shape, using an optical three-dimensional sensor including an observing device and a controllable illuminating device for measuring a contour map of the object, and at least one mirror, comprising the steps of:
- spatially arranging the at least one mirror in at least one field of view of the observing device for measuring a plurality of three-dimensional views of the object, measuring a first of the views by directly observing the object and at least a second of the views by other than directly observing the object;
- illuminating the three-dimensional views by the at least one mirror:
- and
- forming a comprehensive three dimensional view of the three-dimensional views as a function of spatial positions of the sensor and the mirrors.
An apparatus for comprehensive three-dimensional measurement of an object shape, comprising:
- an optical three-dimensional sensor having an observing device, and a controllable illuminating device and at least one mirror for measuring a contour map of the object shape, and a control and evaluation unit,
- said at least one mirror being arranged spatially in a field of view of said observing device for measuring a plurality of three-dimensional views of the object shape, at least one of said three-dimensional views being by directly observing the object shape and at least another of the three-dimensional views being by observing the object shape by said at least one mirror;
- and
- said control and evaluation unit controlling said sensor so that said at least one mirror illuminates certain of the three-dimensional views being performed, said control and evaluation unit registering certain of the three-dimensional views to form a three-dimensional wide angle measurement as a function of spatial positions of said sensor and said at least one mirror.
