Abstract

The invention discloses an augmented reality character image recognition registration method, and the method comprises the steps: carrying out the template image processing through combining downsampling with two-power sampling, and achieving the scale invariance; by intensively extracting character stroke feature points, character features are accurately obtained, the influence of texture features on precision is reduced, and the method is suitable for recognition and registration of text images. Compared with the prior art, the augmented reality character image recognition and registration method provided by the invention is better in time and precision, can still accurately recognize and register when the to-be-recognized text image changes, and shows a better enhancement effect. The method solves the problems that in the prior art, robustness is poor, shielding cannot be solved, application is limited to a certain extent, scale invariance is lacked, efficiency is low, and precision is prone to being affected by complex texture features of the image, and the method is suitable for wide popularization.

Description

Technical field [0001] The present invention relates to the field of image recognition, and in particular, a method of enhancing a literal image identification registration method. Background technique [0002] Enhanced reality is an important branch technology for virtual reality. Its purpose is to be in real time, accurately and accurately, realize the fusion of virtual and real scenes. Enhanced reality has three technical features that have virtual fusion, real-time interaction, and three-dimensional registration, widely used in education, medical, entertainment. [0003] The existing identification registration method is mostly based on computer vision, where the identified identification registration method can bring visual pollution in the actual environment, and there is a steadyness, unable to solve the disadvantages of occlusion, and are subject to certain restrictions in applications. In the feature detection algorithm, the accelerated segmentation test feature (FAST) a...
