Problems solved by technology

However, due to different education categories and different operation categories, different parts of the body of the students have different degrees of movement when performing actions.
It is impossible to focus on a certain body part by directly comparing the student's movements with the standard movements, and for multiple students, each needs to be reconstructed and compared in 3D, resulting in an excessive amount of calculation for the system

Abstract

The invention relates to the technical field of visual perception, in particular to a vocational education system based on visual perception and human body three-dimensional reconstruction. The system comprises an image acquisition module used for acquiring a teaching area image; a component segmentation module which obtains key points and relation affinity field information of students in the teaching area image and segments the students into different components; a key point confidence obtaining module which obtains the confidence of the key points; a component weight obtaining module which obtains component weights in real time according to the number information and the motion degree of the components in the image; a uniformity acquisition module which divides the students into student groups including a plurality of students; and calculates the overall uniformity of the student group according to the features obtained by other modules; and a posture education module which performs three-dimensional reconstruction on the students in the student group with abnormal overall uniformity, and screens out abnormal students through comparison with a standard three-dimensional posture. In vocational education, parts with different vocational operation requirements are emphatically evaluated, and the teaching quality and the detection accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of visual perception, in particular to a vocational education system based on visual perception and three-dimensional reconstruction of human body. Background technique [0002] Vocational education is a type of education system, including vocational school education and vocational training. In the process of vocational training, there are often multiple trainees conducting training and teaching at the same time. Due to the limited resources of teachers, it is impossible to supervise and guide the operation of the students one-on-one, and it is impossible to find the students who made mistakes in time and the specific steps where the mistakes occurred, which has an impact on the quality of education. [0003] In the prior art, it is possible to compare the students' three-dimensional information operation actions with standard actions through the images captured by the monitoring camera in the teaching area...
