[0002] 3D reconstruction (3D Reconstruction) technology refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects. It is a technology for establishing a virtual reality that expresses the objective world in a computer. Yes, when the user scans the object, due to the problem of uneven ambient light, the surface of the object itself has uneven light and shade. This kind of shadow can be called the soft shadow of the object itself, resulting in the final three-dimensional reconstruction. The model has a mottled feeling, which greatly affects the user's senses and experience
In this type of scheme, the user is required to manually select the shaded area, which increases the interaction cost between the machine and the human.

The invention provides a method for eliminating shadow and electronic equipment, and the method can be used for an artificial intelligence (AI) terminal. The method comprises the following steps: the electronic equipment acquires first video information, wherein the first video information comprises multiple frames of images; the electronic equipment displays a first interface, the first interface comprises a first 3D model, the first 3D model is a 3D model obtained by performing three-dimensional reconstruction on an image of a foreground object in each frame of image, and the first interface further comprises a first control; the electronic equipment detects a first operation of a user on the first control; in response to the first operation, the electronic equipment displays a second interface, the second interface comprises a second 3D model, and the shadow value of the second 3D model is smaller than that of the first 3D model. According to the embodiment of the invention, the intelligent degree of the electronic equipment (such as intelligent terminal equipment, such as a mobile phone) can be improved, and meanwhile, the shadow removal effect of the image can also be improved.
Description
technical field [0001] The present application relates to the field of terminals, and more particularly, to a method and electronic device for eliminating shadows. Background technique [0002] 3D reconstruction (3D Reconstruction) technology refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects. It is a technology to establish virtual reality in a computer to express the objective world. Yes, when the user scans the object, due to the uneven ambient light, the surface of the object itself has different brightness and darkness. This shadow can be called the soft shadow of the object itself, resulting in the final reconstructed 3D shadow. The model has a mottled feeling, which greatly affects the user's senses and experience. [0003] The current solutions for removing image shadows include natural image soft shadow removal solutions. In this type of solution, the user is required to manually sel...
