Embodiment Construction

[0115] Starting from MTM, the present invention aims to use somatosensory interaction technology and computer technology to automatically calculate the predetermined time for the personnel participating in the virtual assembly to grasp, move and let go. Specific steps are as follows:

[0116] Step 1. Refer to figure 1 , use Unity 3D to build a virtual assembly environment, and set the grabbing point n on the i-th part ij (x ij ,y ij ,z ij ) (represents the number of grab points, some parts have only one grab point, and some have multiple grab points), add gravity to the part, and configure four base points A on the bottom of the part il (x il ,y il ) (the base point only selects plane coordinates in the virtual assembly, l∈(1,2,3,4), and the base points are connected to each other as a rectangle), at the center point A of the final placement position of the part iq (x iq ,y iq ). (both the base point and the center point are within the first quadrant of the O coordin...

Abstract

The invention belongs to the field of somatosensory interaction, and particularly provides a calculating method for grasp, move and release actions in virtual assembly. The method comprises followingsteps: step one, a virtual assembly environment is constructed with Unity 3D, a grabbing point and base points are set, and palm position points are collected with Leap Motion; step two, the grasp action is identified; step three, the release action is identified; step four, the move action is identified. According to the method, coordinates of hands and coordinates of the grabbing point, the basepoints, a center point and the like marked in Unity 3D are collected with Leap Motion, the standard time of operation of the actions is judged by a ratio of distance to area, and accordingly, the blank in existing market is filled up.

Description

technical field [0001] The invention belongs to the field of somatosensory interaction, in particular to a method for measuring and calculating actions of grasping, moving and letting go in virtual assembly. Background technique [0002] MTM is the most widely used scheduled time method in the world today, and has thus become a unified production process planning and efficiency specification for various units of multinational companies. Grasping, moving and letting go are coherent actions in MTM, in which moving is to move something to a specific place for a predetermined purpose, and the variable factors include factors such as moving distance and moving conditions; grasping is for a predetermined purpose, Fully control one or more objects with the hand so that the next action can be realized. The variable factors are determined by the state of the target object, the size of the target object, and the conditions of grasping; letting go is the target object controlled by the...
