Generation for earth-moving operations

A construction machine, in particular a grader, a dozer or an excavator, the construction machine comprising:

• a tool for performing an earth-moving operation, in particular for digging a trench;
• a control unit for at least partially controlling the earth-moving operation;
• and
• a system according to any one of the preceding claims, the system being operatively coupled with the control unit or comprising the control unit.

A computer-implemented method for planning an earth-moving operation using a construction machine, wherein the construction machine has a tool for performing an earth-moving operation and a machine control unit for at least partially controlling the earth-moving operation, the method comprising:

• receiving three-dimensional measuring data of an uneven terrain in a surrounding of the construction machine in at least a first detection range;
• capturing context image data of the terrain within the first detection range using a context camera having a known position relative to the three-dimensional measuring data and/or to a measuring system capturing the three-dimensional measuring data;
• displaying at least one context image based on the context image data to an operator of the construction machine;
• receiving user input from the operator, the user input being interpretable as or comprising a selection of pixels of the context image;
• interpreting the user input as a selection of pixels of the context image;
• mapping, taking into consideration the known relative position of the context camera, the selection of pixels to a surface of the three-dimensional terrain model;
• determining, based on the mapping, 3D coordinates in the three-dimensional terrain model on the surface;
• and providing the 3D coordinates to the machine control unit for at least partially controlling the earth-moving operation based on the 3D coordinates.
