Summary:A method and a device for non-contact determination of temporal color and/or intensity variations in objects in a scene. 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. A two-dimensional detail image is detected by a detail camera from a third viewing direction and is projected on the overview map. Measurement surfaces in the scene are selected based on criteria which are predetermined depending on parameters on which conclusions are to be drawn from the color variations and/or intensity variations. 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.
