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 present invention provides an outdoor augmented reality application method based on cross-source image matching. The method includes: acquiring a camera image and a rendered image corresponding to the camera image, and processing the camera image and the rendered image to obtain pairwise matching The local camera image block and the local rendering image block; build the deep learning model according to the automatic encoder and the Siamese network, and train the deep learning model; based on the trained deep learning model, the local camera image block and the local rendering image block to be matched are treated. Extract the feature descriptors, and perform cross-source image matching on the local camera image blocks and local rendering image blocks to be matched according to the extracted feature descriptors to obtain cross-source image matching results; obtain cross-source image matching results according to the cross-source image matching results. The corresponding relationship of the images is calculated, and the virtual-real registration transformation relationship is calculated according to the corresponding relationship; the application of outdoor augmented reality is realized according to the virtual-real registration transformation relationship to improve the effect of augmented reality.

Description

technical field [0001] The 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 mainly focuses on 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 unrealistic to use pre-placed markers. , so 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 multi-sensors is not robust to changes in light and occlusion, thus affecting the effect of augmented reality. . SUMMARY OF THE INVENTION [0003] The present invention aims to solve one of the technical problems in...
