New road discovery method and device, equipment and storage medium

Abstract

The invention relates to the field of traffic information service, and provides a new road discovery method and device, equipment and a storage medium. The new road discovery method comprises the steps: collecting new information data in advance, judging whether a vehicle is near a new road information place by analyzing a positioning point of vehicle-mounted equipment carried on the vehicle; whenthe vehicle is near a new road information place, matching the recent track of the vehicle with the existing road network data; taking a part, which cannot be matched with the existing road network,in the track as a suspected new road; and further calling the video data of the vehicle-mounted equipment, and verifying whether the suspected new road is the new road through the road sign recognition and matching technology. Therefore, the new road discovery method can obviously improve the new road information collection and verification efficiency, can accelerate the map product updating progress, does not need collection team field investigation, and reduces the information collection cost.

Description

technical field [0001] The invention relates to the field of traffic information services, in particular to a new road discovery method, device, equipment and storage medium. Background technique [0002] At present, the method of discovering new roads is relatively traditional. The main reason is that various map companies collect new road data and mark new roads through carpet-based on-site collection by the collection team, which leads to slow update of new roads on map products and brings inconvenience to people's travel. [0003] Although new road data can be obtained through the blanket collection of road data by the collection team, this method has obvious disadvantages: 1. Low collection efficiency, slow discovery of new roads, and serious lag in new road data updates; 2. On-site collection will face manpower and material resources As well as the increase of financial resources, the cost is high. Contents of the invention [0004] The invention provides a new road...
