摘要: A method for improving the definition of a digital image whose pixels are memorized light intensity values which are arranged in rows and columns in the form of a starting matrix Axy. A matrix section Aij is enlarged by reflection and subjected to a fast Fourier transform. The transformed matrix Bij is converted by elementary multiplication with an aberration correction matrix Cij to give a correct transformed matrix B′ij. This is transformed back into an intensity matrix A′ij from which a core section is set to a corrected intensity matrix A′xy. Following this, one matrix section after another is stagger-processed until a completely corrected intensity matrix A′xy has been obtained. The correcting function can be determined in different ways, in particular from an MFT of the imaging lens.

摘要: In order to safeguard a hazardous area, in particular the hazardous area of an automatically operating machine, images of the hazardous area are recorded with at least a first and a second image recording unit that are arranged offset from one another. The images of the scene are subjected to three-dimensional scene analyses using different three-dimensional scene analysis methods, and the hazardous area is safeguarded when at least one of the scene analysis methods detects a foreign object.

摘要: A method for reconstructing the profile of structures on surfaces. According to said method, at least two images of the same area of the surface that is to be analyzed are evaluated, said images being recorded from a nearly vertical perspective, for example, and the surface being illuminated from different directions at a flat angle thereto. Elevations or depressions on the surface thus cast a distinct shadow in the recorded images, the position of which varies according to the incident light. Inclined areas can be identified by means of a brighter reflection. The vertical profile of a structure on the surface can be determined, and the shape of a fin can hence be reconstructed, for example, by analyzing shadow contours and outlines of bright areas. Even flat inclination changes can be determined by integrating the shape-from-shading process so as to evaluate brightness patterns such that a 3D reconstruction of the surface can be obtained, which matches the original well.
