Abstract:
1. A computer-implemented image matching method, comprising: receiving a first posed image and a second posed image; extracting one or more image features from the first posed image and the second posed image; comparing the one or more extracted image features from the first posed image with the one or more extracted image features from the second posed image to identify one or more matched features of the first and second posed images based on a feature appearance; grouping one or more of the matched features of the first and second posed images, wherein the grouped matched features of the first and second posed images are associated with a first three-dimensional point; identifying a position of the first three-dimensional point based on a positional triangulation of the grouped matched features associated with the first three-dimensional point; and augmenting the first three-dimensional point with the grouped matched features associated with the first three-dimensional point.
