1. A method for acquiring a texture of a three-dimensional (3D) model, performed by a computing device, the method comprising:
acquiring at least two 3D networks generated based on a target object according to a plurality of angles, the at least two 3D networks including a first correspondence between point cloud information and color information of the target object, and first camera poses of the target object, the first camera pose being used for representing a displacement of the target object relative to a reference position in response to determining that the 3D network is generated;
moving the at least two 3D networks to a same angle according to the first camera poses respectively included in the at least two 3D networks;
acquiring a second point closest to a first point in a first network, the second point being in a second network, and the first network and the second network being respectively different 3D networks of the at least two 3D networks;
acquiring an offset between the first point and the second point;
updating the first correspondence according to the offset, to acquire a second correspondence between the point cloud information and the color information of the target object; and
acquiring a surface color texture of a 3D model of the target object according to the second correspondence.
