Abstract

The invention provides a road map construction method, a device and electronic equipment. The method comprises the following steps: acquiring a road video image and positioning information acquired ina vehicle driving process, wherein the positioning information comprises longitude and latitude information and time information of each collected sampling point; generating a driving route of the vehicle on a base map according to each sampling point in the positioning information; generating a plurality of traffic sign images under the overlooking angle according to the road video image, wherein each traffic sign image carries time information; and splicing a plurality of traffic sign images on the driving route of the base map based on the time information to obtain a road map of the driving route. According to the embodiment of the invention, the road map with relatively high accuracy can be constructed through the data collected in the driving process of the vehicle, the cost is relatively low compared with a laser radar mode, and the requirement of a user on map accuracy 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...
