Title:
ROAD NETWORK MAP IMPLEMENTATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/078499
Kind Code:
A1
Abstract:
A road network map implementation method and apparatus, and an electronic device. The method comprises: by using a grid coordinate system, discretizing a road network to be mapped to obtain a basic road network map representing the road network by using occupied grids (S110); determining a passable direction of each occupied grid in the basic road network map according to direction information of the road network and a connection relationship among the grids (S120); and determining a road network code of the corresponding occupied grid according to the passable direction of each occupied grid, so as to implement a road network map (S130). The road network is discretized by means of a grid coordinate system, so that a subsequently implemented road network map has the basis of being input into a neural network; the passable direction of each occupied grid is determined on the basis of the direction information of the road network and the connection relationship among the grids, and the road network codes of the occupied grids are further determined, so that the road network map having road direction information is implemented and can be extracted by the neural network, and the training effect is improved.
