Abstract: The position of a moving object is estimated with high accuracy using landmark information, and highly accurate state estimation is performed appropriately at high speed. A landmark detection unit obtains a distance between the moving object and each of two or more landmarks as landmark distance information based on observation data obtained by an observation obtaining unit. A candidate area obtaining unit determines a candidate area for a position of the moving object based on the landmark distance information obtained by the landmark detection unit, and obtains candidate area information indicating the determined candidate area. A state estimation unit estimates an internal state of the moving object based on the observation data, the landmark distance information, and the candidate area information to obtain moving object internal state estimation data, and estimates the environmental map based on the candidate area information and the landmark distance information to obtain environmental map data.

Abstract: Provided is a projection system that sets an arbitrary three-dimensional shape as a projection target and properly corrects geometric distortion of a projected image even when a user's viewpoint is not fixed. A projection unit of the projector apparatus projects a test image for first adjustment. A three-dimensional shape measurement unit measures the three-dimensional shape of the projection target. An image capturing apparatus captures the test image for first adjustment projected by the projection unit to obtain a captured image for first adjustment.

Abstract: Even when a high-performance imaging apparatus is not used, luminance unevenness and color unevenness of an image (video) projected on a projection plane by the projection type projector apparatus are appropriately reduced. Using a coefficient Br (0?Br?1) set by a coefficient setting unit, the projection system obtains, based on the gamma characteristic of the entire system of the projection system, a target image for reducing the number of pixels saturated when the image is projected. Then, the projection system performs correction processing using the obtained target image based on the gamma characteristic of the entire system of the projection system and a white value. This reduces the number of saturated pixels of the projected image in the projection system.

Abstract: A moving object controller efficiently generates an environmental map and performs highly accurate state estimation in a short time to appropriately control a moving object. An observation obtaining unit obtains observation data from an observable event. A landmark prediction unit generates a landmark prediction signal including predictive information about a landmark at a current time. A landmark detection unit detects information about the landmark at the current time, and generates a landmark detection signal indicating the detection result. A state estimation unit estimates an internal state of the moving object to obtain data indicating an estimated internal state of the moving object at the current time, and estimates the environmental map based on the landmark detection signal to obtain data indicating an estimated environmental map at the current time.

Abstract: Provided is a projection system that easily and appropriately reduces the geometric distortion of the image projected on the projection plane. The projection circuitry 3 of the projection system 1000 projects a test image onto the projection plane. The three-dimensional shape measurement circuitry 4 measures the three-dimensional shape of the projection plane. The controller 200 generates a control signal. Based on the measured three-dimensional shape data, the projection image adjustment circuitry 1 performs correction processing and rotation processing on a test, in accordance with the control signal, such that the geometrical image distortion is reduced as viewed from the user's viewpoint.
