Abstract

The invention provides a target-matching object recognition method and device and a storage device. The method comprises the steps that a three-dimensional model of a target object is established; a multi-view picture base of the three-dimensional model is generated; Fourier descriptors of picture contours in the picture base are calculated, and a matching base is generated; a real-time object image is acquired, and the image is preprocessed to obtain a comparison image; and the comparison image is matched with an image in the matching base, and a matching result is finally generated. The target-matching object recognition device and the storage device are used for implementing the method. Through the target-matching object recognition method and device and the storage device, good robustness is achieved while the expected object image is effectively recognized.

Description

technical field [0001] The invention relates to the field of pattern recognition, in particular to an object recognition method, device and storage device for target matching. Background technique [0002] In the automatic target recognition technology, the recognition of object shape is the focus of research in the field of pattern recognition, and it is widely used in the field of machine vision. To recognize the shape of an object, one must first find a way to describe the shape of the object. For different ways of describing shapes, many shape description methods have been proposed. Fourier descriptors are simple and efficient, and have become one of the important methods for recognizing object shapes. However, the Fourier descriptor is less robust to image description in a two-dimensional plane, and cannot solve the deformation problem caused by images viewed from different angles in three-dimensional space. Therefore, how to find an object image recognition method th...
