发明名称 AUTOMATIC CONNECTION OF IMAGES USING VISUAL FEATURES
摘要 Aspects of the disclosure relate generating navigation paths between images. A first image taken from a first location and a second image taken from a second location may be selected. A position of the first location in relation to the second location may be determined. First and second frames for the first and second images may be selected based on the position. First and second sets of visual features for each of the first and second image frames may be identified. Matching visual features between the first set of visual features and the second set of visual features may be determined. A confidence level for a line-of-sight between the first and second images may be determined by evaluating one or more positions of the matching visual features. Based on at least the confidence level, a navigation path from the first image to the second image is generated.

主权项 1. A method comprising: selecting, by one or more processors, a first image taken from a first location and a second image taken from a second location; determining, by the one or more processors, a position of the first location in relation to the second location; selecting, by the one or more processors, a first frame on the first image and a second frame on the second image based on the position; identifying, by the one or more processors, a first set of visual features of the first image in the first frame and a second set of visual feature of the second image in the second frame; determining, by the one or more processors, a number of matching visual features between the first set of visual features and the second set of visual features; determining, by the one or more processors, a confidence level for a line-of-sight between the first image and the second image by evaluating one or more positions of the matching visual features; and generating, by the one or more processors, based on at least the confidence level, a navigation path from the first image to the second image.
