A method for generating a photogrammetric corridor map from a set of input images by recovering a respective pose of each image, wherein a pose includes a position and an orientation information of the underlying camera, including steps of: a) receiving a set of input images, b) defining a working set, c) initializing an image cluster, d) further growing the image cluster: d1) selecting one image from the working set that features overlap with at least one image already in the cluster, e) continuing with step b) if there remain images in the working set; if not, f) generating and providing as output the corridor map using the recovered camera poses.

Method and device for generating a photogrammetric corridor map from a set of images

A method for measure the layer thickness of soil coverings, in particular in the case of gas and oil pipelines laid underground, wherein the device to be covered is measured and the coordinates thereof in relation to a specified coordinate system are recorded, where the course of the terrain over the device is measured and a terrain model is determined therefrom and recorded in the specified coordinate system after the soil covering has been applied, and where the layer thickness of the soil covering is determined from the coordinates of the device and from the terrain model.

Layer thickness measurement of soil covering

The method enables automatic triggering of pattern recognition tasks. A histogram of the frequency distribution of the gray-scale values of the image is determined periodically and repeatedly from the available image information. The characteristics of the histogram are determined, and the characteristics are used as the basis for establishing whether a relevant pattern is present. If the relevant pattern is found to be present, the pattern recognition process is initiated.
