Claim 1:
2. An optical observation system, comprising:
an optical observation device including a first image sensor arranged in a first partial beam path defined by the optical observation device and the second image sensor being arranged in a second partial beam path defined by the optical observation device, the optical observation device being configured to record digital images of a three-dimensional observation object;
an illumination device to illuminate the three-dimensional observation object with illumination light having an intensity distribution;
a topography ascertainment device to ascertain a topography of the three-dimensional observation object; and
a shading correction device connected to the at least one image sensor to receive a digital image of the three-dimensional observation object and connected to the topography ascertainment device to receive the topography and configured to correct an inhomogeneity in an image brightness of the digital image of the three-dimensional observation object based on the topography and the intensity distribution,
wherein the optical observation device is embodied to record stereoscopic images, the first image sensor being configured to record a first stereoscopic partial image and the second image sensor being configured to record a second stereoscopic partial image,
wherein the topography ascertainment device is configured to ascertain the topography of the three-dimensional observation object based on the first and second stereoscopic partial images; or
wherein the topography of the three-dimensional observation object is ascertained based on a stereoscopic image of the three-dimensional observation object recorded by a time-of-flight camera system; or
wherein the topography of the three-dimensional observation object is ascertained based on a structured illumination and a distortion of a structure of an illumination in the stereoscopic image of the three-dimensional observation object recorded with the structured illumination; or
wherein the topography of the three-dimensional observation object is ascertained with a laser scanner system.
