Problems solved by technology

[0018] In summary, the disadvantages of the prior art are that the recognition and reconstruction of two-dimensional object images taken from multiple angles and directions cannot be performed, and the speed of recognition and reconstruction is slow
[0019] Therefore, the existing technology still needs to be improved and developed

Embodiment Construction

[0051] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0052] The specific implementation of the two-dimensional image recognition and object reconstruction method of the present invention, the main core point is that by comparing the two-dimensional projection matching degree between the image of the two-dimensional object to be recognized and the three-dimensional model of the constructed object, it will meet the requirement of image feature similarity The object in the attribute library associated with the two-dimensional projection is recognized as an object in the two-dimensional image, and the three-dimensional model corresponding to the two-dimensional projection that meets the similarity requirements of the image features is used to reconstruct the object, and the method of parallel operation is used to speed up the identification and reconstruction. Speed; As for the process...

Abstract

The invention discloses a two-dimensional image recognition and object reconstruction method based on a three-dimensional model database. The method includes the following steps: a three-dimensional model of an object used for a two-dimensional projection is constructed, the three-dimensional model database is established and an correspondingly correlative attribute database is built up; the two-dimensional projection matching degrees of a two-dimensional image of the object to be recognized and the three-dimensional model of the relative object are compared; as for the two-dimensional projections being in accordance with the matching degree requirement, the object in the correlative attribute database is recognized as the object in the two-dimensional image; and the three-dimensional model in the three-dimensional model database which is correlative to the object in the attribute database is used for reconstructing the object. Due to the adoption of the comparison of the two-dimensional image of the object with the two-dimensional projection of the relative three-dimensional model, the aim of recognizing the object in the two-dimensional image of the object is realized and the two-dimensional images of the object which are photographed in a plurality of angles and from a plurality of directions are recognized; moreover, the aim of reconstructing the object in the two-dimensional image is achieved by using the correlative three-dimensional model; in addition, a paralleling calculation method is adopted to accelerate the speed of the reorganization and the reconstruction.

Description

technical field [0001] The invention relates to a two-dimensional image recognition and object reconstruction, in particular to a two-dimensional image recognition and object reconstruction method based on a three-dimensional model library. Background technique [0002] Humans live in a three-dimensional world, so if we want to truly describe the real world, it is best to use three-dimensional technology; however, the traditional method of recording actual scenes and describing actual objects is to use object images. The cost of this method It is relatively cheap and the technology is very mature, and with the development of digital photography technology in recent years, people get more and more realistic two-dimensional pictures; the principle of digital photography technology is the same as the previous photography technology Three-dimensional objects are projected onto a two-dimensional plane to obtain object images, but some three-dimensional shape information has been ...
