3D-camera and method for the three-dimensional monitoring of a monitoring area
First Claim
1. A 3D-camera (10) having at least one image sensor (14a-b) and at least one illumination unit (100) which comprises a light source and which is configured for generating an irregular illumination pattern (20) in an illumination area (12) of the 3D-camera (10), wherein the light source comprises a semiconductor array (104) having a plurality of individual emitter elements (106) in an irregular arrangement, wherein a respective individual emitter element (106) generates a pattern element (112) of the irregular illumination pattern (20), wherein each individual emitter element (106) comprises a point-like emitter surface, and wherein the pattern element (112) generated by the individual emitter element (106) comprises a shape of the emitter surface.
