Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] The "plurality" mentioned herein means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.

[0041] Please refer to figure 1 , which shows a schematic diagram of an implementation environment provided by an embodiment of the present invention, where the implementation environment includes a terminal 110 and a server 120 .

[0042] Terminal 110 is an electronic device with functions of image collection and data transmission. The electron...

Abstract

The embodiment of the invention discloses a picture screening method and device, belonging to the field of image recognition. The method includes: obtaining n crowdsourcing pictures, n≥2, and n crowdsourcing pictures are uploaded by the same terminal; performing target object detection on each crowdsourcing picture to determine candidate crowdsourcing pictures; According to the corresponding geographic location, the candidate crowdsourcing images are clustered. After clustering, the geographic locations corresponding to each candidate crowdsourcing image in the same class are located in the same area; according to the target object detection results, filter out Target crowdsourced pictures, the target object detection results contain characterization parameters indicating the quality of candidate crowdsourced pictures. By adopting the image screening method provided by the embodiment of the present invention, the subsequent entry personnel only need to update the map data according to the effective information in the target crowdsourced image, instead of traversing all the crowdsourced images for image screening, which improves the recognition efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the field of image recognition, and in particular to a method and device for screening pictures. Background technique [0002] When a user uses a navigation application for navigation, the accuracy of the map data in the navigation application will directly affect the final navigation effect. [0003] In order to improve the accuracy of map data in navigation applications, the map platform usually adopts crowdsourcing collection, and the receiving terminal collects and uploads crowdsourcing pictures containing road images in real time. For each received crowdsourced picture, the entry personnel screen out pictures containing specific objects from a large number of crowdsourced pictures through human eye recognition. For example, the entry personnel screens out pictures containing street signs, traffic lights, and illegal cameras, thereby According to the screened crowdsourced pictures, the map data at the...
