Abstract
Technology for matching images (for example, video images, still images) of an identical infrastructure object (for example, a tower component of a tower supporting power lines) for purposes of comparing the infrastructure object to itself at different points in time to detect a potential anomaly and the potential need for maintenance of the infrastructure object. In some embodiments, this matching of images is done using creation of a three dimensional (#D) computer model of the infrastructure object and by tagging captured images with location on the 3D model across multiple videos taken at different points in time.
Claims7
A computer-implemented method comprising:
- receiving a plurality of initial version infrastructure object images, with each initial version infrastructure object image of the plurality showing the same infrastructure object, and with all initial version infrastructure object images being characterized by, at least approximately, parallel viewing vectors;
- adjusting, by machine logic, at least one initial version infrastructure object image to obtain a plurality of adjusted infrastructure image objects respectively corresponding to the plurality of initial version infrastructure object images, with the plurality of adjusted infrastructure object images showing the same infrastructure object aligned with itself across the plurality of adjusted infrastructure object images;
- comparing, by machine logic, the adjusted infrastructure object images with each other to determine a difference data set corresponding to a set of differences between at least two of the plurality of adjusted infrastructure object images;
- and
- analyzing, by machine logic, the difference data set to determine that a potential maintenance condition exists regarding the infrastructure object shown in all of the plurality of initial version infrastructure images.
