A Teaching Method of Virtual Assembly Based on Leap Motion

Abstract

The invention provides a virtual assembling demonstrating and teaching method based on Leap Motion. The method comprises the steps of firstly, conducting three-dimensional modeling on parts of an assembly and conducting correct assembling to obtain an assembly model, then conducting format converting, importing 3dsMax, unifying the material, and then exporting into a universal format of FBX to obtain a three-dimensional model; constructing a virtual assembling scene in Unity3D, assembling the parts, then obtaining gesture motion information and compiling a control view method, utilizing motioninformation of the human hand to grasp and move the virtual parts and conducting a view zooming operation and making an assembler judge the assembly state by observing the color change of the parts to finally complete assembling. The hand precise motion can be accurately captured, control over the interface is achieved, the parts are grasped, assembling is completed, after the parts of multiple formats or the assembly model are converted through the 3dsMax format, virtual assembling is conducted, and certain universality is achieved.

Description

technical field [0001] The invention relates to the technical field of virtual assembly, in particular to a Leap Motion-based virtual assembly teaching method. Background technique [0002] With the rapid development of higher education and vocational technical education, almost all engineering colleges have mechanical engineering-related majors, and the process of machine construction, disassembly and assembly is an important part of cultivating mechanical talents. The training of traditional assembly and maintenance courses has shortcomings such as insufficient venues and assembly equipment, limitations of training time and place, and prone to safety accidents. The virtual assembly training system allows more students to perform repeated exercises before the real assembly training. Students can freely arrange their own time to choose assembly courses for learning, providing a transitional training before the real operation. The virtual assembly environment used. This can...

Problems solved by technology

[0003] However, most of the existing virtual assembly methods have the following shortcomings: First, most virtual assembly mainly relies on the mouse to control the virtual hand for assembly, and does not involve the interaction between real hand movements and the assembly process, even if some systems have motion capture devices such as Kinect, etc. , but it is not accurate enough to capture the fine movements of fingers; secondly, most of the current virtual assembly methods are designed and developed for specific models or components, without considering the generality of mechanical products. Once the product structure changes, it needs to Redesign of assembly system
