Title:
RESPONSIVE LOCALIZATION OF PERSONS BY A NON-STEREO VISION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/151032
Kind Code:
A1
Abstract:
Methods and systems are provided for localizing subjects captured in image data by non-stereo vision and localizing source of captured audio by a computing system, to implement responsive conducting of transactional services by an interactive terminal. Prior to routine operation, the computing system of the interactive terminal may be calibrated by fitting subject bearing angles and subject distances relative to the interactive terminal, from captured images, to two respective regression models. During routine operation, the computing system may perform regression computations upon measurements of detected subjects from captured images to localize subject bearing angles and subject distances. Such image localizations may be further enhanced based on audio localizations, further based on calibration. In these manners, tradeoffs are made to accept margins of error to reduce computational complexity, enabling the interactive terminal as a whole to be implemented and deployed with greater flexibility in components and cost than stereo vision systems.
