摘要： The present invention relates to a system 2 for positioning of a road construction machine 1 of the type paver, in particular asphalt paver or concrete paver, or milling machine, in particular trimmer, surface miner, recycler or soil stabilizer, the system 2 comprises a first measuring unit 3 configured for continuously generating first measuring data in a first detection range 5 during a movement of the road construction machine 1 and comprising at least a first camera and a first LiDAR sensor module, wherein camera and LiDAR data are recorded covering the first detection range 5 with minimum repetition rate and minimum resolution, and several markers 7. The system 2 further comprises a data memory, wherein the data memory has stored a 3D design model referenced with respect to a 3D construction site coordinate system and information about a known absolute reference of the several markers 7 in the 3D construction site coordinate system, and a computing unit. The computing unit is configured for identification of the several markers 7 within the first measuring data and determination of relative positions of the several markers 7 within the first detection range 5 within the first measuring data, determination of a pose of the first measuring unit 3 and therewith the pose, particularly in six degrees of freedom, of the road construction machine 1 in the 3D construction site coordinate system based on the determined relative positions of the several markers 7 and the stored information about the known absolute reference of the several markers 7 and deriving steering commands for the road construction machine 1 so as to work in accordance with the 3D design model.
