Abstract (en)

[origin: WO2018099556A1] Image processing device for producing in real-time a digital composite image from a sequence of digital images of an interior of a hollow structure recorded by an endoscopic camera device so that the composite image has a wider field of view than the images of the sequence of images, the image processing device comprising: a selecting unit, a key point detection unit, a transforming unit and a joining unit, wherein the transforming unit comprises a key point matching unit configured for determining key point pairs, wherein the transforming unit comprises a transformation determination unit configured for determining a transformation for transforming a further image into a global coordinate system, wherein the transformation for transforming the further image into the global coordinate system is a concatenation of a perspective transformation, an isomorphic mapping and a Mobius transformation, wherein parameters of the transformation for transforming the further image into the global coordinate system are determined from at least some of the key point pairs, and wherein the transforming unit comprises a transforming execution unit configured for transforming the further image into the global coordinate system by using the transformation for transforming the further image into the global coordinate system in order to produce a transformed further image.
