Information processing method and device, equipment and storage medium

Abstract

The embodiment of the invention discloses an information processing method. The method comprises the steps of obtaining a boundary edge set of holes in the surface of a triangular mesh model to be repaired, wherein the boundary edge set is composed of boundary edges of the holes; determining an included angle between a normal of each boundary triangular patch and a scanning axis to form a boundary included angle set, wherein the boundary triangular patch is a triangular patch where each boundary edge in the boundary edge set is located; determining the scanning state of the holes according to the number of included angles greater than a first included angle threshold in the boundary included angle set; acquiring a boundary vertex set of the holes according to the scanning state, wherein the boundary vertex set is composed of boundary vertexes of the holes; and performing triangulation on the holes according to the boundary vertex set. In addition, the embodiment of the invention also discloses an information processing device, equipment and a storage medium.

Description

technical field [0001] The embodiments of the present application relate to the field of information processing, and relate to, but are not limited to, an information processing method, device, device, and storage medium. Background technique [0002] With the emergence of various depth cameras for general consumers, 3D scanning and reconstruction technology based on depth cameras has developed rapidly. Before the emergence of consumer-oriented depth cameras, the input data of 3D reconstruction technology usually only has red, green and blue (RGB) images. By taking RGB images from different angles of the object, the 3D model of the object can be reconstructed. However, the accuracy of the model obtained by the early 3D reconstruction technology is often low, and the scope of application of the technology is limited. The emergence of consumer-level depth cameras provides depth image data for 3D reconstruction technology, which greatly reduces the difficulty of reconstruction...

Problems solved by technology

[0004] Hole repair methods include: volume data repair and surface direct repair, among which, surface direct repair is to repair holes and other defects directly on the mesh surface, and for the triangular mesh model reconstructed from depth data, use surface direct repair There are still holes at the bottom of the triangular mesh model obtained by hole repair, resulting in poor repair effect
