Sit-up counting method and device, electronic device and storage medium

Abstract

The invention relates to a sit-up counting method. The method comprises the steps: 1, delimiting a recognition region through a camera, and finding a human shape in the recognition region through a human shape target detection algorithm; 2, preprocessing the human shape; 3, the distance HF between the human-shaped head H and the foot F, the distance OH between the human-shaped head H and the thigh O and the distance OF between the human-shaped foot F and the thigh O are calculated, the cosine value of the angle A is calculated according to the HF, the OH and the OF, in the movement process, the positions of the foot F and the thigh O are not changed, the position of the head H is changed at any time, meanwhile, the values of the OH and the OF are not changed, and the magnitude of the HF is changed at any time; 4, calculating the angle A according to the cosine value CosA of the angle A, wherein A = ArcCosA; 5, judging the size relation between the minimum value of the angle A and the preset value T in the exercise process, if the minimum value of the angle A is smaller than the preset value T, carrying out sit-up counting once, and if the minimum value of the angle A is larger than the preset value T, not carrying out sit-up counting. By means of the sit-up counting method and device, the problem that sit-up counting depends on manual work in the prior art is solved, and sit-up counting is achieved.

Description

technical field [0001] The present application relates to the field of computer vision, in particular to a sit-up counting method, device, electronic device and storage medium. Background technique [0002] Sit-ups, a way to exercise your body. Lie on your back, keep your legs together, lift your hands up, use your abdominal muscles to contract, swing your arms forward, quickly get into a sitting position, continue to bend your upper body forward, touch your feet with your hands, and bow your head; then return to a sitting position. Training sit-ups is an effective way to improve the physical fitness of the people. The existing sit-up technique basically relies on manually judging whether the sit-up posture is standard and counting, which wastes human resources and may cause inconsistent judgment standards manually, resulting in large counting errors. [0003] At present, no effective solution has been proposed for the problem that the counting of sit-ups in the related ar...
