Abstract:
1. A system for change invariant scene recognition of an environment by an agent, the system comprising: an image camera configured to use image sensors to capture images for the agent; a grouping module configured to group the images into situation image sets that are identified as being at locations and edges of a navigation graph; an image database configured to contain the situation image sets; a query module configured to query the image database by comparing a first image signature of a navigation image with second image signatures of the situation image sets, wherein the situation image sets are loaded as separate sets from the image database; a probability module configured to identify a selected situation image set based on a probability that the selected situation image set has an individual image that matches the navigation image; a feature matching module configured to identify one or more matching images in the selected situation image set that match the navigation image and to provide a navigation location for the agent based on the one or more matching images; and at least one processing device configured to execute the grouping module, the query module, the probability module, and the feature matching module.
