GROUND MARK EXTRACTION METHOD, MODEL TRAINING METHOD, DEVICE AND STORAGE MEDIUM

摘要

Disclosed in the present application is a ground mark determination method, comprising: acquiring a point cloud grayscale map, the point cloud grayscale map comprising a road segment map; running a mark extracting network model, acquiring ground mark information from the road segment map, the mark extracting network model being used to extract ground marks included in the road segment map, the ground mark information comprising information concerning each of the ground marks extracted by the mark extracting network model, the ground mark being travel indication information marked on the ground of the road segment; according to the ground mark information, determining a target ground mark from each of the ground marks. In the embodiments of the present application, a mark extracting network model is used to acquire information concerning ground marks in a road segment map, and the ground marks in the road segment map is determined according to the ground mark information, thereby improving the efficiency and accuracy in determining the ground mark in the road segment map.
