Method for object automatic recognition and three-dimensional reconstruction in image processing

Abstract

The invention discloses an object automatic recognition and three-dimensional (3D) reconstruction method in image processing and uses a general counting device and a piece of image recording equipment. The method includes the following steps: according to image types recorded in the image recording equipment, image samples of real samples are recognized to form an object image sample database and a recognition and 3D reconstruction knowledge base is formed; object image samples which are similar enough with object images to be recognized and reconstructed are found according to an object attribute database in the object image samples which is provided with the same structure with the object image sample database; and corresponding 3D models extracted from the object 3D model base of the object image samples are reconstructed by a way of three-dimension. The method of the invention solves the disadvantage that the prior art can only aim at specific objects and being base on specific knowledge, improves the automation degree and the speed of the recognition and the reconstruction and satisfies the urgent need of digital technologies of digital cities and digital medicine, etc. for the automatic efficient image recognition and reconstruction of various objects.

Description

technical field [0001] The invention relates to an image processing method, in particular to a method for automatically recognizing and three-dimensionally reconstructing various objects in image processing. Background technique [0002] The following is a technical dictionary known from the prior art: [0003] Knowledge base: According to the knowledge application field characteristics, object characteristics (object information at the time of acquisition), use characteristics, attribute characteristics, etc. in the knowledge base, it is constituted into an easy-to-use and structured organization form. There can also be a special section of the knowledge base, often referred to as the canonical method base. If the solution to certain problems is certain and inevitable, it can be directly stored in the typical method library as a part of the fairly certain solution to the problem. [0004] The knowledge in the knowledge base includes: application domain characteristics, ob...

Problems solved by technology

[0021] The purpose of the present invention is to provide a method for automatic recognition and three-dimensional reconstruction of objects in image processing. In view of the prior art, only specific objects in the reconstructed image can be recognized, or the recognition and reconstruction of objects in the image can only be carried out based on specific knowledge, which cannot meet the three-dimensional requirements. Digital city, 3D digital medicine and other 3D digital technologies have an urgent need for automatic recognition and 3D reconstruction of various objects in images. A method that can be applied to various objects and integrate various knowledge is proposed to support automatic recognition of objects in images. Method for recognition and 3D reconstruction
