Abstract:
1. A method for the contour measurement and/or deformation measurement of an object, comprising: irradiating one of an entire object at once or otherwise sequentially irradiating parts of said object with structured light that is emitted by a radiation source and is coherent light or partially coherent light, picking up the light reflected by the object by a camera with an imaging sensor, and producing a first image, including at least one overexposed and/or underexposed region associated with said first image and a region including meaningful data associated with said first image, with a first adjustment of one or more camera operating parameters of amplification, diaphragm opening, shutter speed, and/or one or more additional operating parameters of the camera and/or with a first adjustment of the luminous intensity of the radiation source which is adapted to a first image region of a first part of said object or said entire object, producing a second image, including at least one further overexposed and/or underexposed region associated with said second image and a region including meaningful data associated with said second image, with a second adjustment of the camera and/or the radiation source which is adapted to a second image region of said first part of said object or said entire object, wherein the at least one overexposed and/or underexposed region associated with said first image corresponds to said region including meaningful data associated with said second image, and wherein the at least one further overexposed and/or underexposed region associated with said second image corresponds to said region including meaningful data associated with said first image; and combining both first and second images, both of said images respectively providing information per pixel to provide a composite image containing measurable contour and/or deformation information about both the first and second image regions of said first part, and repeating said producing steps for further parts of said object until said entire object is irradiated.
