Estimating the term…
A camera for recording 3D image data using a light sectioning process is provided that has an illumination unit to project a light pattern in a focal plane, an image sensor having a plurality of light reception elements in an image plane, a reception optics upstream of the image sensor and having an objective plane, and a control and evaluation unit that is configured to generate the 3D image data by evaluating the light pattern in a recording of the image sensor, wherein the image plane is tilted with respect to the focal plane. In this respect, the reception optics has at least one metaelement here that compensates an oblique light incidence on the light reception elements.
