Abstract
The present invention relates to a method of monitoring the condition of structural components, in which an optical sensor in conjunction with a computing unit ascertains image deviations from successive images of the structural components to be monitored, and therefrom ascertains changes in shape of the structure. Robust three-dimensional scanning of the structural components is possible when using two or more sensors. The invention further relates to an apparatus for monitoring the condition of structural components having an optical sensor and an apparatus having two or more sensors. Finally the invention relates to an aircraft in which the methods or apparatuses according to the invention are used.

12. A method of monitoring the condition of structural components of an aircraft, which comprises the following method steps:
-
producing images of the structural component with two or more mutually spaced cameras; communicating the images to at least one computing unit; ascertaining the geometry data of a monitored region of the structural component from the images; ascertaining geometry deviations of discrete regions of the structural component from the comparison of the ascertained geometry data with a reference geometry data set; and ascertaining changes in shape of the structural component from the geometry deviations by the at least one computing unit, wherein the size of objectives of the cameras and the spacing of the cameras depend on the size of the monitored region of the structural component to be monitored. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. An apparatus for monitoring the condition of structural components of an aircraft, comprising:
-
two or more mutually spaced cameras for producing images of the structural component; and at least one computing unit, wherein the computing unit is adapted to receive the images, to ascertain the geometry data of a monitored region of the structural component from the images, to ascertain geometry deviations of discrete regions of the structural component from the comparison of the ascertained geometry data with a reference geometry data set, and to ascertain changes in shape of the structural component from the geometry deviations, wherein the size of objectives of the cameras and the spacing of the cameras depend on the size of the monitored region of the structural component to be monitored. - View Dependent Claims (20)
