  • Earthmoving flow vector generation using node and connection input graph
    Patent number: 11603646
    Abstract: Techniques for generating earthmoving flow vectors for assisting control of a construction machine are disclosed. A design elevation map of an earthmoving site may be obtained. The design elevation map may include a plurality of design elevation points of the earthmoving site. An actual elevation map of the earthmoving site may be obtained. The actual elevation map may include a plurality of actual elevation points of the earthmoving site. A dual-layer input graph may be formed based on the design elevation map and the actual elevation map. The dual-layer input graph may include a plurality of nodes related through a plurality of connections. A flow graph may be generated by solving the dual-layer input graph. The flow graph may include a set of flow vectors indicating movement of the earth within the earthmoving site.
