Abstract: A high-precision positioning result in self-positioning is provided. An information processing apparatus acquires a first coordinate position inside an image of each light source included in an image captured with an imaging device among multiple light sources whose coordinate positions are known in a three-dimensional space to derive at least a coordinate position or an orientation of an own device in the three-dimensional space based on a coordinate position of the light source included in the image in the three-dimensional space and the first coordinate position. The apparatus estimates a height of the imaging device in the three-dimensional space to perform positioning processing using information on the estimated height of the imaging device, acquires a second coordinate position of the light source on the image corresponding to the positioning processing result, and corrects the height of the imaging device based on the first coordinate position and the second coordinate position.

Abstract: An information processing apparatus performs positioning processing to acquire coordinate positions inside images of light sources included in an image captured with an imaging device among multiple light sources (position indicators) whose coordinate positions in a three-dimensional space are known to derive at least either of a coordinate position and an orientation of an own device (moving body) in the three-dimensional space based on coordinate positions of the light sources in the three-dimensional space included in the image and the coordinate positions inside the images of the light sources. The information processing apparatus uses information on light sources in which an angle of a light source from the imaging device to a predetermined direction or a prospective angle between light sources in a horizontal direction satisfies a predetermined condition to derive at least either of the coordinate position and the orientation of the own device.

Abstract: A position obtaining device includes a processor. The processor, in response to a condition being met, derives a first attitude angle as an attitude angle of the device based on first light sources and positions thereof on an image obtained by a first camera; in response to the attitude angle of the device being known, derives a three-dimensional position of the device based on two or more second light sources and positions thereof on an image obtained by a second camera, and in response to a predetermined number of second light sources or more being captured in the image, derives the three-dimensional position and a second attitude angle as the attitude angle of the device; and integrates a result of the first attitude angle and a result of the three-dimensional position and the second attitude angle to estimate the attitude angle and the three-dimensional position of the device.

Abstract: An optical communication apparatus includes a light receiving unit, a wavelength band determining unit and an estimating unit. The light receiving unit receives light which changes to predetermined wavelength bands in a predetermined cycle according to communication object information, for a predetermined light reception period. The wavelength band determining unit determines each wavelength band of the light received by the light receiving unit. The estimating unit estimates that a wavelength band of the light received by the light receiving unit is any one of the predetermined wavelength bands, in a case where said wavelength band determined by the wavelength band determining unit is not any one of the predetermined wavelength bands.

Abstract: A reception device acquires multiple frames for a period corresponding to an optical signal format and determines whether a color change region within the frames includes any of red (R), green (G), and blue (B), which is a first color, and black (Bk) in the non-emission period corresponding to a header, which is a second color. Moreover, when the color change region within the multiple frames for a period corresponding to an optical signal format includes any of red (R), green (G), and blue (B) and black (Bk), the reception device controls decoding of a bit data string corresponding to the red (R), green (G), and blue (B) colors in the color change region to acquire communication target information.

Abstract: In a smartphone, the imaging mode of an imager or the display mode of a display is changed from a normal mode when an image of an optical communication region is captured. More specifically, a process of lowering the contrast of the entire image (frame), a process of superimposing an icon image on the candidate region, a masking process for lowering the contrast of the candidate region, a process of reducing the count of display frames by image averaging or thinning, or a zoom limiting process of limiting the upper limit of the zoom ratio of the imager or the upper limit of the enlarged display magnification on the display is performed.
