Problems solved by technology

[0002] In related technologies, the application of augmented reality is mainly concentrated in indoor scenes, and pre-placed markers are used to assist virtual and real registration. However, in outdoor scenes, due to the increase in scale and complexity of outdoor scenes, it is unrealistic to use pre-placed markers. , so most outdoor augmented reality applications are usually sensor-based positioning and vision methods, and are mainly used in static scenes, and the fusion accuracy of multi-sensors is not robust to light changes and occlusions, thus affecting the effect of augmented reality

Abstract

The invention provides an outdoor augmented reality application method based on cross-source image matching, and the method comprises the steps: obtaining a camera image and a rendering image correspondingly matched with the camera image, and carrying out the processing of the camera image and the rendering image, so as to obtain a local camera image block and a local rendering image block, whichare matched in pairs; constructing a deep learning model according to the automatic encoder and the twin network, and training the deep learning model; extracting feature descriptors of the local camera image block and the local rendering image block to be matched based on the trained deep learning model, and performing cross-source image matching on the local camera image block and the local rendering image block to be matched according to the extracted feature descriptors to obtain a cross-source image matching result; obtaining a corresponding relationship of the cross-source images according to a cross-source image matching result, and calculating a virtual-real registration transformation relationship according to the corresponding relationship; the application of the outdoor augmented reality is realized according to the virtual-real registration transformation relationship, so that the augmented reality effect is improved.

Description

Technical field [0001] The present invention relates to the technical field of outdoor augmented reality, in particular to an outdoor augmented reality application method based on cross-source image matching, a computer-readable storage medium and a computer device. Background technique [0002] In related technologies, the application of augmented reality is mainly concentrated in indoor scenes, and pre-placed markers are used to assist virtual and real registration. However, in outdoor scenes, due to the increased scale and complexity of outdoor scenes, it is not realistic to use pre-placed markers Therefore, most outdoor augmented reality applications are usually based on sensor-based positioning and vision methods, and are mainly used in static scenes, and the fusion accuracy of multiple sensors is not robust to light changes and occlusion, which affects the effect of augmented reality . Summary of the invention [0003] The present invention aims to solve one of the technica...
