Abstract

The invention provides a road map construction method and device and electronic equipment. The method comprises: acquiring a road video image and positioning information acquired by vehicle-mounted equipment in a vehicle driving process, wherein the positioning information comprises acquired longitude and latitude information of each position point; generating a driving route of the vehicle on a basic map according to the discrete position points in the positioning information and the vehicle driving state data; generating a road top view according to the road video image, wherein the road topview is an image set containing time information and traffic signs; and based on the time information, splicing a road top view on the driving route of the basic map to obtain a road map of the driving route. According to the embodiment of the invention, the road map with relatively high precision can be constructed through the data of various vehicle-mounted devices of the vehicle, the cost is relatively low compared with a laser radar mode, and meanwhile, the requirement of a user on the map precision is ensured.

Description

technical field [0001] The present application relates to the field of map technology, in particular, to a method, device and electronic equipment for constructing a road map. Background technique [0002] At present, the high-precision road map construction method mainly relies on lidar for map scanning and drawing. The data is constructed, and the error is relatively large, which is difficult to meet the user's demand for map accuracy. Contents of the invention [0003] In view of this, the purpose of the embodiment of the present application is to provide a road map construction method, device and electronic equipment, through which the data of various on-board equipment of the vehicle can be used to construct a road map with high accuracy and high cost compared with the laser radar method. Low, while ensuring the user's demand for map accuracy. [0004] According to one aspect of the present application, an electronic device is provided, which may include one or more...
