Abstract

The invention provides a map updating method and device, and a storage medium. The method comprises the steps of obtaining a to-be-updated map; acquiring a plurality of frames of first images in a to-be-updated map range; identifying a first processing object in the first image; generating three-dimensional point cloud data including the first processing object according to the first image; and updating the map to be updated according to the three-dimensional point cloud data. According to the map updating method and device and the storage medium provided by the invention, the map updating cost can be reduced.

Description

technical field [0001] The invention relates to computer application technology, in particular to a map updating method, device and storage medium. Background technique [0002] With the development of science and technology, the application of maps is becoming more and more extensive. Among them, high-precision maps, as one of the core technologies of unmanned driving, are crucial to the positioning, navigation, control and safety of unmanned vehicles. [0003] Generally, after a road or road indication information (traffic lights, identification signs or ground markings, etc.) is changed, it is usually necessary to update the high-precision map. In the prior art, it is usually necessary to use professional collection vehicles for on-the-spot collection, and judge which roads or road indication information in the high-precision map have changed based on the collected images, so as to update the high-precision map. [0004] However, professional collection vehicles in the p...
