Embodiment 1

[0015] According to an embodiment of the present invention, an embodiment of a video correction method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0016] figure 1 is a flowchart of a video correction method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0017] Step S12, collecting a first image and a second image of the user, wherein the first image is an image collected when the user watches the area of ​​the camera device, and the second image is an image collected when the user watches the area of ​​the screen.

[0018] Specifically, in the above step S12, an imaging device may be...

Embodiment 2

[0044] The present application also provides a video correction device, which can be used to implement the above video correction method, such as figure 2 As shown, the apparatus may include: a collection unit 20, configured to collect a first image and a second image of the user, wherein the first image is the image collected when the user watches the area of ​​the camera device, and the second image is the image collected by the user watching the screen area The image collected at the time; the extraction unit 22 is used to extract the coordinate system in the first image and the coordinate system in the second image, and calculate the affine matrix from the coordinate system of the first image to the coordinate system of the second image; correct A unit 24 is configured to use an affine matrix to perform affine transformation processing on the collected initial video to generate a corrected target video.

[0045] In this embodiment, the first image and the second image of ...

Abstract

The invention discloses a video correction method and a video correction device. The video correction method includes: acquiring a first image and a second image of a user, wherein the first image refers to an acquired image when the user views a camera shooting equipment area, and the second image refers to an acquired image when the user views a screen area; extracting a coordinate system of the first image and a coordinate system of the second image and computing an affine matrix from the coordinate system of the first image to the coordinate system of the second image; subjecting an acquired initial video to affine transformation processing by adopting the affine matrix so as to generate a corrected object video. Compared with the prior art, the video correction method and the video correction device have the advantages that technical problems of complexity and large computing resource of a prior video correction method for eye contacts between chat users are solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a video correction method and device. Background technique [0002] With the development of Internet technology, people in multiple different regions can communicate face to face only through cameras and computers. However, when we use chat software (such as WeChat, Michat, MSN, etc.) There is a distance difference between the camera and the center of the screen, resulting in a lack of eye-to-eye communication between chat users. For example, the camera of a laptop computer is often set at the top of the screen. When user USER1 and user USER2 are chatting, user USER1 often looks at The center area of ​​the screen, instead of the camera, then for user USER2, the display screen of user USER2 will show that the eyes of user USER1 are looking down, and eye contact is an indispensable part of human-to-human communication. It makes video chatting not as natural as usual face-to-face c...
