Map generation method and device, equipment and storage medium

The embodiment of the invention provides a map generation method and device, equipment and a storage medium. The map generation method includes obtaining a first initial code and a second initial code for a first type of map elements and a second type of map elements in a training map, respectively, the first region and the second region being composed of the first type of map elements and the second type of map elements, respectively. An indication of a positional relationship of the first region and the second region in the training map is obtained. A first code and a second code for the first type of map element and the second type of map element, respectively, are generated by at least one update of the first initial code and the second initial code based on the indication such that a similarity of the first code and the second code is associated with a positional relationship. In this way, codes for different types of map elements can be obtained, which can describe the possible positional relationship o
