Embodiment 1

[0069] The embodiment of the present invention provides a method for searching content resources. like figure 1 As shown in FIG. 2 , it is a flowchart of a method for searching content resources according to an embodiment of the present invention. The method for searching content resources in the embodiment of the present invention includes the following steps:

[0070] S101. Acquire text features and visual features of a query image.

[0071] In the embodiment of the present invention, the query pictures may include but not limited to pictures on the Internet, pictures stored in albums, pictures taken by cameras, or hand-drawn sketches.

[0072] The embodiment of the present invention can receive the query picture sent by the client based on various API (Application Programming Interface, Application Programming Interface) interfaces of protocols such as HTTP (HyperText Transfer Protocol, hypertext transfer protocol), HTTPS, and can also be input by the user. The web page ...

Embodiment 2

[0085] On the basis of the first embodiment, the embodiment of the present invention provides a method for searching content resources. like figure 2 As shown in FIG. 2 , it is a flowchart of a method for searching content resources according to an embodiment of the present invention. The method for searching content resources in the embodiment of the present invention includes the following steps:

[0086] S201. Acquire text features and visual features of a query image.

[0087] In an embodiment, a picture classification model may be used to identify the picture content of the query picture, and text features may be extracted from the query picture. For example, a picture classification model can be trained based on the convolutional neural network algorithm and according to the vertical category, and a picture of Tyrannosaurus rex can be input to the picture classification model, and the picture classification model can output the text classification label "tyrannosaurus...

Embodiment 3

[0123] On the basis of the second embodiment, the embodiment of the present invention provides a method for searching content resources. like Figure 5 As shown in FIG. 2 , it is a flowchart of a method for searching content resources according to an embodiment of the present invention. The method for searching content resources in the embodiment of the present invention includes:

[0124] ①Query picture (query): As the overall input of the system, it is generated by the browser client, including the content of the picture and the URL address of the picture.

[0125] Wherein, the form of the picture is not limited, and may be a picture file uploaded by the user, a picture taken by a camera, or a hand-drawn sketch.

[0126] ②Network interface: Receive and analyze the query pictures sent by the client, and return the search results of content resources to the client. Possible implementations include but are not limited to various API interface definition forms based on protoc...

Abstract

The invention proposes a method, device and server for searching content resources. The method includes: acquiring the text feature and visual feature of the query picture; comparing the textual similarity between the text feature of the query picture and the text feature of each content resource; comparing the visual feature of the query picture with the visual feature of each content resource The visual similarity of each content resource; determine the content search result from each content resource according to the text similarity and visual similarity between the query picture and each content resource. The query technical solution of the embodiment of the present invention combines text similarity and visual similarity in the process of searching content, so that the required content resources can be accurately searched.

Description

technical field [0001] The present invention relates to the technical field of computer networks, and in particular, to a method, a device and a server for searching content resources. Background technique [0002] With the development of computer technology, many new content resources have appeared, such as panorama pictures, panoramic videos, three-dimensional (3D) models, three-dimensional animations and their applications in virtual reality (VR) and augmented reality (augmented reality). , AR) scene display, etc. At the same time, photography techniques (such as fisheye lenses), modeling techniques, and programming tools are also evolving, making it easier and easier to generate the aforementioned content resources. On the Internet, this new content resource is also appearing more and more. Compared with traditional text, two-dimensional pictures, ordinary video and audio, etc.), these content resources have coherence, multi-linearity, multi-angle, presence, large spac...
