1. A measuring system for determining a filling volume of a filling material in a container, comprising:
a 3D camera that can be positioned to record at least one 3D image of at least one partial region of the container interior;
a radar-based fill-level measurement device for creating a fill-level profile of a filling material surface, the fill-level measurement device including:
an antenna arrangement via which according to a principle of digital beam shaping radar signals in a direction of the filling material can be emitted, and via which corresponding reception signals can be received after reflection of the radar signal on the filling material surface; and
a transmitting/receiving unit designed to generate the radar signals according to the principle of beam shaping, and according to the principle of beam shaping, at least based on the reception signals, to create the fill-level profile in a solid-angle-dependent manner; and
an evaluation unit designed to create a data set based on the at least one 3D image, wherein the data set represents a geometry of the at least one partial region of the container interior, and to determine the filling volume based on the data set and the fill-level profile,
wherein the 3D camera is designed as a component of the antenna arrangement of the fill-level measurement device.
