Large-Scale Map-Making
Current mapping algorithms using Consistent Pose Estimation (CPE) algorithms can successfully map areas of 10 square meters, using thousands of poses. However, the computation to construct the map grows as O(n log n), so larger maps get increasingly difficult to build. We present an abstraction method for postponing the growth in computation. This method solves a much smaller problem in the spa...
متن کاملMap Making as a Support for Cooperation
This research deals with search tasks of agents, in particular, a meeting task where agents try to gather into a single location starting from distributed arrangements. The meeting task is ubiquitous in cooperation because agents need to approach one another if they wish to work together effectively. For example, in cooperative computation, multiple processes must come near in order to reduce c...
متن کاملSemi-autonomous Map-making and Navigation
Map construction and task-oriented navigation constitute two important capabilities for mobile robots. Despite their value, progress to date in the development of stand-alone robots endowed with these capabilities has been limited. We describe an architecture for mobile robots based on the concept of semi-autonomy that employs communication with a human advisor in order to simplify the tasks of...
متن کاملA Map-Making for the Planck Surveyor
We present a parallel implementation of a map-making algorithm for CMB anisotropy experiments which is both fast and efficient. We show for the first time a Maximum Likelihood, minimum variance map obtained by processing the entire data stream expected from the Planck Surveyor, under the assumption of a symmetric beam profile. Here we restrict ourselves to the case of the 30 GHz channel of the ...
متن کاملMap Morphing: Making Sense of Incongruent Maps
Map morphing is an interactive visualization technique that provides a user-controlled, animated translation from one map to another. Traditionally, overlay mechanisms are used to present layers of information over a single projection. Map morphing provides a way to relate maps with significant spatial and schematic differences. This paper presents the morphing technique and the results of a co...
