| Abstract: |
| The work aims to improve the current situation of low visualization and low training quality of assembly training for coal mine drilling rig. Combined with the modeling advantages of UG and 3DS Max animation software, the 3d model reconstruction and texture mapping processing methods were discussed, and the model structure tree was built. Assembly system was achieved by c# language to write the core of the script and study the related assembly animation path control. Different UI interface schemes of the system were designed, and the optimal scheme was obtained by calculating the weight scores of different audiences through coordinate method and average method. Based on Unity3D virtual engine platform, a set of system for coal mine drilling rigs was developed and implemented from the perspective of the first person. The HTC VIVE Pro external headset was used to dock the system for debugging, operation and final release to realize the man-machine interaction operation. The research shows the complete assembly process of the mechanical assembly workshop, gives the trainees novel and vivid teaching experience through friendly man-machine interaction, and preliminarily explores the virtual reality technology in coal mine drilling rig intelligent direction interact with remote control. At the same time, it also provides a new method reference for the market promotion and application of coal mine drilling rig. |
