Method and arrangement for the simultaneous measurement of material properties and geometric information, in particular for the detection of foreign bodies

摘要

Small aircraft for inspection often use cameras. However, cameras have the disadvantage that objects which are deliberately designed so that they are easily overlooked are often not recognizable in the camera image. The invention relates to a device and a method by means of a receiver or a camera a significantly improved recognition of objects by differentiation to achieve different materials. In addition, the arrangement provides important information for the navigation and cartography of the inspected area. The invention is based on the emission of structured light and light of different wavelength distribution and the analysis of the geometric and temporal intensity distribution recorded by the camera. In a typical embodiment, the object to be examined is irradiated with a plurality of patterns of light, which has a suitable wavelength-dependent intensity distribution, which in conjunction with the color resolution of the camera enables a higher spectral resolution.
