  • Publication number: 20210247189
    Abstract: There is provided a positioning apparatus, a positioning method, and a program that make it possible to perform positioning with a high degree of accuracy using an acceleration sensor and an angular velocity sensor. A movement vector is estimated using a machine learning model on the basis of acceleration of a device and an angular velocity of the device, the movement vector indicating a movement amount and a movement direction of the device, the acceleration being detected by an acceleration sensor that is used to detect the acceleration, the angular velocity being detected by an angular velocity sensor that is used to detect the angular velocity. Then, the estimated movement vector is integrated, and a relative position of the device is calculated. For example, the present technology is applicable to a positioning apparatus that measures a position of, for example, a pedestrian.

  • Publication number: 20200388052
    Abstract: An information processing device, an information processing method, and a program are provided. The information processing device includes a virtual object control unit that generates a control parameter that controls display of a first virtual object corresponding to a first real object and a second virtual object corresponding to a second real object on the basis of first posture information indicating a posture of the first real object and second posture information indicating a posture of the second real object, and a determination unit that makes a determination related to contact between the first virtual object and the second virtual object. The virtual object control unit generates the control parameter on the further basis of a result of the determination.

  • Publication number: 20200309963
    Abstract: A mobile object according to the present technology includes a sensor, a map location estimation unit, a relative location estimation unit, a relative location estimation unit, a GNSS reception unit, and an absolute location estimation unit. The sensor acquires surrounding information. The map location estimation unit estimates a self location in a local map on the basis of an output of the sensor. The GNSS reception unit receives global navigation satellite system (GNSS) positioning information using a first carrier phase distance. The absolute location estimation unit estimates a self absolute location on the basis of the GNSS positioning information using the first carrier phase distance, GNSS positioning information using a second carrier phase distance, and a relative location, the GNSS positioning information using the second carrier phase distance being received by another mobile object.

  • Publication number: 20190243001
    Abstract: Provided is an information processing apparatus intended to address problems in which positioning devices simply equipped with a plurality of antennas will fail to perform the carrier positioning. The information processing apparatus includes a receiving unit having a plurality of antennas located at second positions (Pa, Pb) and capable of receiving a carrier wave transmitted from a satellite, and a processing unit configured to perform positioning of a set first position (Po) on the basis of second phase information obtained by correcting first phase information of carrier waves respectively received by a plurality of the antennas.
