A Bending Action Recognition Method

Abstract

The invention belongs to the field of gesture recognition, in particular to a bending motion recognition method. The recognition method includes the following steps: step 1, method preparation for measuring and calculating the range of bending motion; step 2, judging the bending motion of the staff; the present invention requires the staff to assemble or disassemble the parts at the designated position, when the corresponding bone length is less than At the standard distance, in the vertical XOY plane, the feet are used as the base point, and the eccentricity of the ellipse is given, and the bifocal position of the ellipse is adjusted according to different bending movements to obtain different ranges of motion activities. According to the length of the bones and the knees The drop point recognizes the bending action. The invention starts from the model method and aims at fully considering the change of the distance between the feet of the operator, and designs a method for recognizing the bending movements of the operator on site through computer programming.

Description

technical field [0001] The invention belongs to the field of gesture recognition, in particular to a bending motion recognition method. Background technique [0002] The model value calculation method is to measure the time according to the performance of different parts of the body. This method is tested in the workshop environment and compared with MTM-1 and MTM-2. Adopted by various manufacturing enterprises. Bending action is an action evaluation method in the model method, and the marked time is B17. This action records the entire process from standing to bending, squatting, touching the ground with one knee, touching the ground with both knees, and then returning to the original state. The time is 17MOD. [0003] There have been related researches on bending movements. Patent CN 107783654A discusses the automatic recognition of bending movements by constructing three planes through human skeleton coordinates, which can recognize bending movements when the operator is...

[0003] There have been related researches on bending movements. Patent CN 107783654A discusses the automatic recognition of bending movements by constructing three planes through human skeleton coordinates, which can recognize bending movements when the operator is standing normally, but this method does not take into account If there is a change in the standing distance between the feet, there will be a huge error when one knee touches the ground and both knees touch the ground and then measured with the plane set by the bone length, which limits the scope of application. In addition, the plane limit is a broad definition, and the accuracy to be considered
