Title:
SIGNAL PROCESSING APPARATUS, SIGNAL PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/009749
Kind Code:
A1
Abstract:
The present technology relates to a signal processing apparatus, a signal processing method and a program which enable an own-position and orientation to be estimated with a high degree of accuracy. This signal processing apparatus: receives distance measurement information between a first ultra wide band (UWB) device disposed in a predetermined space, and a second UWB device provided in a mobile body, by means of UWB communication by way of the second UWB device; detects, from an image obtained from an imaging unit provided on the mobile body, a feature point based on a light source disposed in the predetermined space, the light source having a lighting timing that is controlled, by means of a server for controlling the first UWB device, on the basis of a time lag between the imaging unit and the server, and tracks the feature point between frames; estimates an own-position and orientation on the basis of the feature point of the light source; and adjusts the own-position and orientation on the basis of the distance measurement information. This technology can be applied to own-position and orientation estimating systems, for example.
