1. A measuring system for checking a measured-image state and/or a calibration quality for a stereo measured image, comprising:
a first image capturing apparatus configured to capture from a first viewing angle at least one first measured image of a measurement object in a scene;
a second image capturing apparatus spaced apart from the first image capturing apparatus and configured to capture from a second viewing angle which differs from the first viewing angle at least one second measured image of the measurement object in the scene;
an output apparatus; and
an evaluation apparatus designed to generate a stereo measured image from the at least first measured image and the at least second measured image by way of stereo reconstruction, with depth information being comprised in the stereo measured image for individual pixels of the stereo measured image;
characterized in that the evaluation apparatus is designed to check a measured-image state of the at least first measured image and/or the at least second measured image for the presence of at least one capturing defect; and/or to check the calibration quality for the stereo measured image on the basis of calibration parameters of the first and/or second image capturing apparatus; and
should the at least one capturing defect overshoot or undershoot a predetermined threshold value, to transmit a first alert to the output device, and/or, should the calibration quality overshoot or undershoot a predetermined quality limit value, to transmit a second alert to the output device, with the output device being configured to output the first and/or second alert.
