Abstract: An optoelectronic sensor for detecting objects in a monitored zone is provided, wherein the sensor comprises a laser scanner having a deflection unit rotatable about an axis of rotation for scanning the monitored zone with at least one scanning beam; a first distance measurement unit for determining 3D measurement points of the respective objects impacted by the scanning beam using a time-of-flight method; a panorama camera having a panorama optics and having an image sensor with a plurality of light reception elements for detecting picture elements; and a control and evaluation unit that is configured to fuse the 3D measurement points and the picture elements. In this respect, the optical axis of the panorama camera and the rotation axis coincide.
