Face capture device convenient for tracking

Abstract

The invention provides a face capture device convenient for tracking. Face emotion recognition and identity recognition are carried out on face data through a three-dimensional face positioning modeling technology to obtain face emotion information and identity information of a person; the face emotion information is input into a state evaluation module for state evaluation, and state evaluation information is sent to an interactive display; meanwhile, teacher face checking is achieved, a man-machine interaction user is locked on the teacher, and the influence of irrelevant personnel or students on classroom teaching can be effectively avoided; sound sources of an actual speaker are positioned through sound source positioning, the pitch angle, azimuth angle information and component discrimination structure of the actual speaker are obtained by analyzing and calculating the coordinates of different sound sources, the denoising performance is guaranteed through the partial self-adaptivetechnology, incoherent noise and coherent noise are effectively restrained, and human voice acquisition in a complex scene is achieved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary teaching equipment, and in particular relates to a human face capture device which is easy to track. Background technique [0002] With the development of artificial intelligence, the use of artificial intelligence technology to empower traditional industries has attracted more and more attention. In the field of education and teaching, attendance management based on face recognition and smart classrooms based on augmented reality are in the ascendant. With the development of electronic information technology and network technology, intelligent teaching has been widely used in daily teaching. Today, as education is becoming more and more informatized, the teaching process can be optimized, the teaching efficiency can be improved, and the teaching process can be promoted in a richer display form. Quality improvement. In today's emphasis on quality education, educational psychologists believe tha...

Problems solved by technology

Usually special image acquisition equipment and control systems are required, such as special cameras or camera arrays, special identification cards, high-performance computers, special software, etc. The effect of classroom interaction is good, but high hardware costs and transformation costs are required. At the same time, artificial markers The development of design and display models requires professional skills and special operations, which increases the workload of teachers and the difficulty of training

[0004] However, in the process of research and practice of the existing technology, it is found that most of the current schools use large class teaching. Due to the large number of students, it is difficult to supervise the learning of the students, and it is difficult for the teacher to accurately judge the classroom learning status of each student. And understand each student's mastery of knowledge, so as to find out a teaching strategy and method suitable for all students, and because many human factors such as the teacher's own teaching experience also play a certain role in restricting students' emotional judgment, thus affecting to student learning and growth
