Abstract: A chart generation unit generates an adjustment chart, and a projection unit projects the adjustment chart onto a circular cylinder. A parameter acquiring unit acquires 12 parameters in total, relating to the positions of four corners and middle points of a top side and a bottom side of a chart and lateral expansion of the chart, the chart being input by a user through manipulations of an operation unit. A transform function determination unit calculates, from the total of 12 parameters, an accurate transform function for projecting an image onto the circular cylinder. An image conversion unit applies geometric transformation to the image based on the calculated transform function.

Abstract: To increase the frequency of executing a loop closing process, and to reduce an accumulated error in a local device position, and the like. A rotational image picker of an autonomous movement device picks up an image while performing a rotational action. An image memory stores information on the picked-up image. A map memory stores a created map. A position estimator estimates the local device position. A similar image searcher searches, from the image memory, the image that has a similarity level of equal to or greater than a predetermined similarity level. A map corrector corrects the map stored in the map memory when the similar image searcher founds the image that has the similarity level of equal to or greater than the predetermined similarity level.

Abstract: To quickly recover from a status in which a local device position estimation is unavailable. A movement processor of an autonomous movement device executes a drive process for a driver so as to move autonomously. A position estimator estimates the local device position. An estimation determiner determines whether or not the estimation result of the local device position by the position estimator is uniquely defined. A movement process controller controls the movement processor so as to move to a position where the estimation result of the local device position by the position estimator is uniquely defined when the estimation determiner determines that the estimation result is not defined uniquely.
