Abstract

The invention discloses a head posture detection method and device and computer equipment. The method comprises the steps that event time sequence signals and RGB video data in the moving process of a to-be-detected object are acquired; respectively screening out an event data stream and a key RGB video stream at the head posture change moment of the to-be-detected object from the event time sequence signal and the RGB video data, and carrying out framing processing to obtain an event image sequence and a key RGB image sequence; outputting the event image sequence and the key RGB image sequence into a trained fusion model, respectively extracting event modal features and image modal features, and fusing the event modal features and the image modal features to obtain a head posture feature image of the to-be-detected object; predicting a head posture angle of the to-be-detected object according to the head posture feature image; according to the method, the head posture is estimated by using the visible light-event bimodal image, the change moment of the head posture can be effectively screened and captured, and accurate estimation can also be realized under the conditions that the illumination condition is not ideal, partial shielding exists and the like.

Description

technical field [0001] The present application relates to the technical field of education management, and more specifically, to a head posture detection method, device and computer equipment. Background technique [0002] For the evaluation of teachers' teaching quality or credibility, in the past, the method of conducting questionnaire surveys on students was mainly used. This method often consumes a lot of time and manpower, has low efficiency, is not time-sensitive, and is not convenient for teachers to adjust teaching behavior strategies in a timely manner. In addition, in the classroom teaching scene, the scientific quantification of teacher teaching behavior recognition through classroom videos faces many problems, such as: lighting changes, motion blur, and complex backgrounds. [0003] Head pose estimation is a very important application in the field of computer vision and pattern recognition. It plays an important role in the study of human behavior and attention,...
