Embodiment Construction

[0052] A method for recognizing and evaluating pedal movements in virtual assembly operations, the specific process is as follows:

[0053] Step 1: Build the pedal scene

[0054] refer to figure 1 , put the Kinect V2 device horizontally, and keep a distance of 1m from the ground in the virtual scene; use Kinect V2 to collect 25 human skeleton points including head, neck, shoulder center, left thumb, right thumb, left fingertip, right fingertip , left hand, right hand, left wrist, right wrist, left elbow, right elbow, left shoulder, right shoulder, spine, hip center, left hip, left knee, left ankle, left foot, right hip, right knee, right ankle, Right foot; where, A 1 (x 1,i ,y 1,i ,z 1,i ) represents the coordinate point of the left buttock of the i-th frame, 25 frames per second, and 0.04 seconds per frame; A 2 (x 2,i ,y 2,i ,z 2,i ) represents the coordinate point of the left knee of the i-th frame, 25 frames per second, 0.04 seconds per frame; A 3 (x 3,i ,y 3,i ...

Abstract

The invention belongs to the field of somatosensory interaction, in particular to a method for recognizing and evaluating a pedal motion in a virtual assembly operation. The method comprises the following steps: step 1, constructing a footstep scene; 2, recognizing that foot movement; 3, evaluating that pedal movement. The invention utilizes Kinect V2 equipment to collect human skeleton data for reverse obtaining of the center of the foot and the ankle from the Kinect V2 coordinates, the pedal movement is judged according to the foot speed, the angle between the ankle-to-foot vector and the XOY plane and the distance between the foot and the pedal center point, and the angle between the knee-to-ankle vector and the knee-to-hip vector is evaluated according to the ankle region. The above method fills in the blank of the existing market.

Description

technical field [0001] The invention belongs to the field of somatosensory interaction, in particular to a method for recognizing and evaluating pedal movements in virtual assembly operations. Background technique [0002] The modeling method is a standard method of timing movements invented by the Australian Heidi in 1966. The basic principle of the model method is based on ergonomic experiments, and the following three points are summarized: [0003] 1. All human-operated actions include some basic actions. Through a large number of experimental studies, the model method summarizes the actions in actual production into 21 types. [0004] 2. The time values ​​required by different people to do the same action (under the same conditions) are basically equal. [0005] 3. When using different parts of the body to move, the time value of the movement is proportional to each other (for example, in the model method, the movement of the hand is twice the movement of the finger,...
