According to a method for virtual enhancement of a camera image, a camera image depicting an object is generated. A geometric description of a virtual auxiliary object as a surface in space and a pose of the auxiliary object with respect to the object are specified, wherein the auxiliary object separates part of the object from the rest of the object. An enhanced image is generated based on a superimposition of the camera image with a representation of the auxiliary object depending on the geometric description and the pose of the auxiliary object by a computing unit and displayed on a display device. The enhanced image is generated and displayed in such a way that the auxiliary object has a spatially variable transparency.
