Abstract: An information comparison unit (53) (comparison unit) of an RSU (10a) (information processing apparatus) compares first data (D1) related to a positional relationship between a vehicle (V) and an object existing around the vehicle, the first data (D1) being obtained from a first sensor unit (59) that is mounted on the vehicle (V) by a vehicle information reception unit (50) (first acquisition unit) and that obtains information related to travel control of the vehicle (V), with second data (D2) related to a positional relationship regarding objects existing on a road (R), the second data (D2) being obtained by an object detection unit (52) (second acquisition unit). Subsequently a correction information generation unit (54) generates correction data (Dc) to be used for correcting an output of the first sensor unit (59) based on a comparison result of the information comparison unit (53), and then the information transmission unit (56) (transmission unit) transmits the correction data (Dc) to the vehicle (V).

Abstract: The present disclosure relates to an autonomous mobile device, a control method, and a program which enable higher-speed self-position estimation with higher accuracy and with a smaller calculation load. Provided is an autonomous mobile device including: a sensor unit including at least a first sensor that detects an angular velocity, a second sensor that is installed in a housing and detects a speed of a wheel, and a third sensor that detects a displacement amount on a two-dimensional plane; and a self-position estimation unit that estimates a self-position on the basis of parameters calculated by the sensor unit, the self-position estimation unit using a predetermined parameter suitable for a predetermined condition among the parameters of the respective sensors calculated by the sensor unit when estimating the self-position. The present disclosure can be applied to, for example, an autonomous mobile robot device.

Abstract: The present technology relates to a signal processing device, a signal processing method, a program, and a mobile device enabling to obtain an occupancy grid map in which an appropriate path can be set.
The signal processing device includes: a map creation unit configured to create an occupancy grid map indicating a presence or absence of an object in a unit of a grid on the basis of first sensor data from a first sensor used to detect the object in surroundings of a mobile device; an attribute setting unit configured to set an attribute of the grid of the occupancy grid map on the basis of an attribute of the object; and a correction unit configured to correct the occupancy grid map on the basis of an attribute of the grid. The present technology can be applied to, for example, a system that controls automatic driving.
