Research And Implementation Of Virtual Assembly Of Coal Mining Equipment Based On Leap Motion

In the field of coal mining equipment manufacturing and assembly,because traditional manufacturing and assembly of large mechanical mobile inconvenience and high cost of assembly,assembly training site constraints such as time,already more and more can't satisfy people's needs,has increased the coal winning machine,digging machine equipment such as the difficulties in the process of the design and development of new products.In recent years,the rapid development of virtual reality technology,make its have become main research direction in the field of computer vision and human-computer interaction,virtual assembly technology derived from virtual reality technology has become an important part of virtual reality technology,in the field of virtual reality technology and virtual simulation has been widely research and application.Virtual assembly technology can determine the optimal sequence of assembling,disassembling and reassembling coal mining equipment in the process of assembly,verify and modify the assembly process,and analyze the availability,manufacturability and maintainability of the assembly.In this case,it is more necessary for advanced virtual assembly and scene simulation technology to develop a more practical and efficient virtual assembly method for coal mining equipment.Based on the technology of LAN collaboration,this paper uses Leap Motion as the main hardware device to carry out virtual assembly of coal mining equipment through multi-person collaborative gesture control.Firstly,the 3d model is imported,based on Leap Motion sensor,obtain gesture data,and accurately calculate the moving speed,position and direction of the hand for gesture recognition;Then,to take the ollision detection by ray tracing.If there is any collision,the model transformation coordinates are rotated to realize the pick up and assembly of assembly parts;Finally,through in the technology of LAN,the use of Unity for multi-user LAN interconnection,and networking the virtual experiment scene.Under the multi-user gesture control,the interaction between the operator's hand and the assembly part in the virtual scene is realized,and the assembly part is split and assembled.This paper puts forward the methods to solve the coal winning machine,digging machine and other mining equipment design assembly difficult problem in the process of research and development,can be implemented in the assembly process of coal mining equipment more than gestures collaborative control,broaden the space of operators,virtual assembly job is no longer just limited to a space of the operators.
