[0033] Such as figure 1 As shown, the image processing method of the embodiment of the present invention includes:

[0034] In step 101, a visible light image and depth information obtained by photographing the same scene are obtained.

[0035] In this step, by acquiring visible light images and depth information of the same physical scene, data support is provided for the construction of the next three-dimensional scene. Wherein, for each pixel in the visible light image, there should be a depth data corresponding to it. Depth data actually refers to the calculated distance between the shooting object and the shooting device.

[0036] Step 102, according to the obtained visible light image and depth information, calculate and obtain the scene three-dimensional space point cloud data through a preset algorithm.

[0037] In this step, according to the visible light image and the depth information, the 3D point cloud data of the scene can be obtained through the preset algori...

Abstract

The present invention provides an image processing method. The method comprises the steps of acquiring a visible light image and the depth information through shooting the same scene; according to the acquired visible light image and the depth information, obtaining the three-dimensional point cloud data of the scene based on a preset algorithm; according to the three-dimensional point cloud data of the scene obtained through calculation, conducting the three-dimensional reconstruction of the scene, generating a three-dimensional geometric model and constructing a virtual scene; and conducting the rendering treatment on the constructed virtual scene. The embodiment of the present invention also provides a corresponding mobile terminal. According to the image processing method provided in the embodiment of the present invention, images of different lighting effects in different 3D illumination conditions can be obtained, and the user experience is improved. The problem in the prior art that the images of different lighting effects in different 3D illumination conditions cannot be pre-viewed and stored without changing the physical scene by means of the mobile terminal can be solved.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to an image processing method and a mobile terminal. Background technique [0002] At present, most of the camera imaging on mobile terminals is to reproduce the real scene as the basic effect. With the diversified needs of users for mobile terminal imaging effects, virtual light and shadow and object appearance texture replacement technologies that are more in line with individual needs have been developed. [0003] The current virtual light and shadow imaging technology in smart terminals generates shadows in two-dimensional image space based on the key feature points of specific objects, which is not only limited to specific object categories, but also cannot realize different light source types, light colors and The mixed lighting effect generated by the light direction; the replacement of the appearance texture of the object in the current image processing technology ...
