Monoscopic overview images of the scene are detected with first and second overview cameras from two different viewing directions, and calculated to form a stereoscopic overview map.

Light emitted by the measurement surfaces is detected in a spatially-resolved and wavelength-resolved manner in a continuously-captured series of measurement images in a predetermined spectral range. The measurement surfaces are analyzed in the measurement images with respect to temporal variation of the intensity and/or color of the light, and the results displayed.
