Title:
METHOD AND APPARATUS FOR POSITIONING SOUND SOURCE USER, AND COMPUTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/212608
Kind Code:
A1
Abstract:
The present application relates to artificial intelligence and blockchain technology. Disclosed is a method for positioning a sound source user, comprising: acquiring a specified orientation corresponding to a sound source recognized by sound source positioning, and a visual centerline orientation corresponding to a spatial position where a robot is currently located; according to the specified orientation and the visual centerline orientation, obtaining a pre-rotated spatial region span; according to the pre-rotated spatial region span, controlling the robot to rotate, and rotating such that the specified orientation is located within a visual range of the robot; determining whether a user image of a specified user is acquired within the field of view range of the robot; if so, acquiring action data of the specified user, processing the action data in a preset way to obtain a processing result, and inputting the processing result to a VGG network for recognition calculation so as to obtain an action type; receiving a data result outputted after the VGG network performs the recognition calculation, and determining, according to the data result of the VGG network, whether a sound source orientation is consistent with the specified orientation; and if so, determining that the specified user at the specified orientation is a sound source user, thereby improving the positioning accuracy.
