Abstract: The present technology relates to a signal processing device, a signal processing method, and a program enabling estimation of a self-position and posture with high accuracy. A signal processing device receives distance measurement information between a first ultra wide band (UWB) device arranged in a predetermined space and a second UWB device provided in a mobile object through UWB communication via the second UWB device, detects a feature point based on a light source from an image obtained from an imaging unit, and performs tracking between frames, in which the light source is arranged in the predetermined space and has a lighting timing controlled by a server on the basis of a time lag between the imaging unit provided in the mobile object and the server that controls the first UWB device. The signal processing device estimates a self-position and posture on the basis of a feature point of the light source, and corrects the self-position and posture on the basis of the distance measurement information.

Abstract: The present disclosure relates to a terminal device, a position posture estimation method, and a program that enable environment-independent display of AR content. A position estimation unit estimates an absolute position posture of an own device on the basis of a correspondence between a three-dimensional position included in object data of an object of interest to which a user pays attention and a position, on a camera image of the user, of the object of interest appearing in the camera image. The technology according to the present disclosure is applicable to, for example, an AR device that displays AR content on images of a real space.
