The invention provides a method and a device for updating navigation information. The method comprises the following steps: acquiring live-action images of an on-site road by using an acquisition vehicle, recognizing first sign parameters of a first traffic sign in the live-action images, and acquiring a geological position of the first traffic sign; determining a first search area by taking the geological position as a center, and checking road sets matched with the type of the first traffic sign within the first search area in a preset road databank; determining a second search area by taking the geological position as a center, and checking an optimal road which is the shortest from the geological position within the second search area in the preset road databank, wherein the included angle of the direction of the optimal road and the driving direction of the acquisition vehicle is smaller than a preset angle; judging whether the optimal road is in the road set or not, and according to judgment results, updating or adding information of the first traffic sign for the optimal road. Therefore, road matching can be achieved in automatic acquisition and recognition of signs, artificial operation is reduced, and operation requirements are lowered.
Description
Technical field [0001] The present invention relates to the technical field of electronic navigation, in particular to a method and device for updating navigation information. Background technique [0002] With the gradual development of the navigation industry, it has become more and more closely related to people's lives, and people are increasingly valued more accurate and real-time geographic information services. The core factor of the navigation industry is the storage and update of navigation geographic data. The collection and update of road signs is particularly important. The existing road sign collection is mainly completed by manual adjustment and drawing, which requires a lot of manpower, and this has extremely high requirements on the operation of the operators, and requires a lot of energy and time of the operators, so the collection efficiency is low and it is difficult to adapt to the renewal of road construction; In addition, due to the limited energy of the op...
