Embodiment Construction

[0042] The technical solution of the present application is described below in conjunction with the accompanying drawings.

[0043] In the description of the present application, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" means one or more, and "plurality" means two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0044] It should be noted that, in this application, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design described herein as "exemplary...

Abstract

The invention discloses an image generation method and device. The method comprises the steps of acquiring a first image of a shooting target and a first ambient light angle used for indicating the relative position relation between an irradiation light source and the shooting target when the first image is shot; obtaining a first 3D model generated by fusing the depth information of the shootingtarget, the plurality of second images and the first lighting information; wherein the plurality of second images are a plurality of two-dimensional images shot from a plurality of angles of the shooting target; wherein the first lighting information comprises a first illumination angle which is the same as the first ambient light angle and first light intensity of which the corresponding brightness is greater than or equal to a preset brightness threshold; and according to the first image and the first 3D model, performing fusion to generate a third image. By adopting the method, when a userperforms selfie in a dark environment, the 3D model containing the first lighting information can be fused with the actually shot three-dimensional image to obtain the selfie image which does not generate stereoscopic impression and skin detail loss, so that the user experience is better.

Description

technical field [0001] The present application relates to the technical field of terminal equipment, and in particular to an image generation method and device. Background technique [0002] With the continuous development of terminal equipment technology, multiple camera devices may be installed on the terminal device, and the multiple camera devices may include a front camera, and a user may use the front camera to take a selfie. However, when in a low-light environment, due to insufficient light, the three-dimensionality and skin details of the image obtained by the selfie are usually missing, there are more noises, and the user experience is poor. [0003] At present, in order to prevent insufficient light from affecting the selfie effect, supplementary light is usually provided through the display screen of the terminal device or the built-in fill light. Specifically, when the user takes a selfie, the terminal device can detect the ambient light brightness of the shooti...
