Abstract
The invention relates to a self-propelled construction machine, in particular a road milling machine or a slipform paver, which can carry out translational and/or rotational movements for a planned project on a terrain. In addition, the invention relates to a method for visualising the working environment of a construction machine moving on the terrain, in particular a road milling machine or a slipform paver. The construction machine comprises an image recording unit for recording an image segment of the terrain located in a coordinate system (X, Y, Z) dependent on the position and orientation of the construction machine on the terrain, and a display unit for displaying the image segment of the terrain. Moreover, the construction machine comprises a data processing unit which is configured in such a way that a depiction of a part of the project located in the image segment is superimposed on the image segment of the terrain displayed on the display unit, such that the project is visualised in the image segment. The display unit thus displays not only the actual image segment, but also a virtual image of the project, thus widening the perception of the machine operator. As a result, the machine operator can identify on the display unit whether the project forming the basis of the control matches the reality.

19. A self-propelled construction machine comprising:
-
a chassis supporting a machine frame and comprising front and rear wheels or running gears for moving the machine in a working direction; a working tool for working a terrain; an image recorder fixed relative to the machine frame and configured to record an image segment of the terrain in a first coordinate system dependent on a position and orientation of the construction machine on the terrain; a display configured to display the image segment of the terrain; a data storage comprising project data describing a shape and location of at least one project in a second coordinate system independent of the position and orientation of the construction machine, and a data processor configured to superimpose a depiction of at least part of the at least one project located in the image segment on the displayed image segment of the terrain, wherein at least part of the at least one project is visualised in the image segment. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
