Embodiment 1

[0031] refer to figure 1 , which shows a flow chart of the steps of the method for determining the authenticity of a picture in an embodiment of the present disclosure, including:

[0032] Step 101 , detecting a target area from at least two target pictures, where the target area is an area in the target picture that has the same object to be photographed.

[0033] Wherein, the target picture may be obtained from the application platform, or may be obtained from other platforms.

[0034] Target areas vary according to application scenarios. For example, if the target picture can be a store picture provided by a merchant on a commodity sales platform, it is necessary to identify the environmental area of ​​the store from the picture; or, the target picture can also be a product picture provided by a merchant on a commodity Identify the commodity area.

[0035] It can be understood that different target pictures may be pictures taken at different angles and with different cam...

Embodiment 2

[0047] refer to Figure 4 , which shows a flow chart of the steps of the method for determining the authenticity of a picture in another embodiment of the present disclosure, specifically as follows.

[0048] Step 201 , for each target picture, detect the target object, and obtain the position information of the target object if the detection is successful.

[0049] Wherein, the location information is represented by two-dimensional coordinates, and the number of coordinates is different for different shapes of the target objects. For example, for a rectangle, the coordinates of the two diagonal positions can be directly extracted as the position information of the rectangle; for a rhombus, the coordinates of the four corners can be extracted as the position information; for a circle, the coordinates of the center of the circle can be used as the position information.

[0050] In practical applications, there may be a relative positional relationship between the target object...

Embodiment 3

[0098] refer to Figure 6 , which shows a structural diagram of an apparatus for determining authenticity of a picture in an embodiment of the present disclosure, specifically as follows.

[0099] A target area detection module 301, configured to detect a target area from at least two target pictures, where the target area is an area in the target pictures that has the same shooting object.

[0100] The 3D model creation module 302 is configured to establish a 3D space for the target area to obtain a set of points forming the 3D space when the target area is detected from the target picture.

[0101] A plane fitting module 303, configured to use the point set to perform plane fitting to obtain a reference plane.

[0102] An authenticity judging module 304, configured to determine the authenticity of the target picture through the reference plane and the point set.

[0103] To sum up, the embodiments of the present disclosure provide a device for determining the authenticity of...

Abstract

An embodiment of the present disclosure provides a method, device, electronic device, and readable storage medium for determining the authenticity of a picture. The method includes: detecting a target area from at least two target pictures, and the target area is the target area There is an area of ​​the same shooting object in the picture; in the case that the target area is detected from the target picture, a three-dimensional space is established for the target area to obtain a point set forming the three-dimensional space; using the point set to perform plane A reference plane is obtained through fitting; the authenticity of the target picture is determined through the reference plane and the point set. The plane can be fitted through the 3D model of the picture, and the authenticity of the picture can be judged. The workload is small, and it is helpful to identify the authenticity of various pictures.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of picture recognition, and in particular, to a method, device, electronic device, and readable storage medium for determining the authenticity of a picture. Background technique [0002] On the online sales platform, in order to help users obtain business information, merchants are required to provide pictures representing business information. And the authenticity of these pictures needs to be determined to really help users. [0003] In the prior art, the patent application with application number 2017104843429 proposes a face image authentication method based on perspective distortion characteristics. The main steps include: 1. Recognize the key points and contours of the face in the 2D image; 2. Obtain the key points in the corresponding 3D face model according to the pre-stored 2D image and 3D face model; 3. Based on the 2D image and 4. Optimizing the camera parameters based on...
