SIGNAL PROCESSING APPARATUS, SIGNAL PROCESSING METHOD, AND PROGRAM

Title:

SIGNAL PROCESSING APPARATUS, SIGNAL PROCESSING METHOD, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2017/057041

Kind Code:

A1

Abstract:

This technology relates to a signal processing apparatus, a signal processing method, and a program that allow highly accurate calibration. The signal processing apparatus is provided with: a first position calculation unit that calculates the three-dimensional position of a target in a first coordinate system from a stereo image captured by a stereo camera; a second position calculation unit that calculates the three-dimensional position of the target in a second coordinate system from a sensor signal from a sensor that can acquire position information in at least one of a horizontal direction and a vertical direction, and position information in a depth direction; a correlation detection unit that detects the correlation between the target in the first coordinate system and the target in the second coordinate system; and a positional relationship information estimation unit that estimates positional relationship information between the first coordinate system and the second coordinate system on the basis of the detected correlation. This technology can be applied, for example, to a signal processing device for sensor fusion.
