Abstract
A Method for generating scaled terrain information while operating a bulldozer. The bulldozer may include a driving unit comprising a set of drive wheels, a motor connected to at least one of the drive wheels, a blade for altering the surface of the terrain, at least one camera for capturing images of the environment, the camera being positioned and aligned in a known manner relative to the bulldozer, and a controlling and processing unit. A method may include moving the bulldozer while concurrently generating a set of image data by capturing an image series of terrain sections with the at least one camera so that at least two images of the image series cover an amount of identical points in the terrain, and either applying a simultaneous localization and mapping (SLAM) algorithm or a stereo photogrammetry algorithm to the set of image data and thereby deriving terrain data.
