Document Type and Number:
WIPO Patent Application WO/2021/238664
Kind Code:
A1
Abstract:
A method and device for capturing information, and a method, device, and system for measuring level of attention. The method for capturing information comprises: sequentially acquiring video frames captured by a video capturing device (101); utilizing a first deep learning model to detect whether a person is present in the video frames (102); insofar as a person is present in the video frames, utilizing a second deep learning model to process the video frames so as to generate a person bounding box in respect of the person, and assigning a corresponding person identifier to the person bounding box (103); utilizing a third deep learning model to recognize the image in the person bounding box so as to recognize feature information of the person (104); writing person history data into a database (105), where the person history data comprises timestamps and identifiers of the video frames, coordinate information of the person bounding box, the person identifier, and the feature information.
