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: A location positioning device for a moving body acquires, via a communication device, a captured image from a camera in which an imaging direction has changed from a first direction to a second direction, the captured image including at least one marker disposed in space and at least one moving body that moves in the space, detects, based on the captured image and initial data, a change of the imaging direction from the first direction to the second direction, and acquires, based on the captured image, location data of the at least one moving body without returning the imaging direction of the camera in a real world to the first direction from the second direction.

Abstract: A remaining battery capacity measuring device within a control device of a mobile apparatus measures a remaining battery capacity level of a battery. The light-emission control device, in a period separate from a transmission period for transmitting an ID, in accordance with the remaining charge amount of the battery, performs changing of a hue of light emitted by an LED, and setting no-data and a no-data period. Alternatively, the light-emission control device, in the period separate from the transmission period for transmitting the ID, in reaction to the remaining battery capacity level of the battery, changes a luminosity of the light emitted by the LED.

Abstract: A waste toner collection container includes a housing main body, a detection chamber with an opening and a waste toner introduction inhibition member. The housing main body collects waste toner therein. The detection chamber engages with the housing main body and enables a sensor to determine whether the waste toner reaches a predetermined amount, by interrupting a light path of the sensor. The opening opens toward the housing main body. The waste toner introduction inhibition member seals the opening to inhibit the waste toner in the housing main body from being introduced into the detection chamber before the waste toner in the housing main body reaches the predetermined amount, and is fractured by a pressing force of the waste toner to permit the waste toner to be introduced into the detection chamber as the waste toner in the housing main body reaches the predetermined amount.
