Design And Implementation Of Human-computer Interaction For Continuous Casting 3D Simulation System

Iron and steel metallurgy is one of the pillar industries of China.Since the reform and opening up,China's rapid economic development is inseparable from the increase in steel output and quality.In order to train excellent continuous casting engineers,higher requirements are asked for training and Simulation of continuous casting process.With the continuous improvement of computer performance and the development of 3D simulation technology,virtual reality technology has made great progress.The method of gesture interaction in virtual reality is studied in the context of continuous casting simulation system.The main work and achievements are as follows:First,a data glove is made.The data glove selects STM32 single-chip microcomputer to collect hand motion posture data from MPU6050 sensor,and transmits the data to Unity3 D engine through wireless Bluetooth module.Experiments show that the data glove can provide data to the system stably,and the system has no stuttering phenomenon.Secondly,a dynamic gesture recognition method based on HMM is proposed.The hidden Markov model is researched in depth,and the gesture interaction recognition model is established by adding noise and normalizing the data generated by the data glove.The proposed algorithm is more than 90% correct for the 8 gestures defined.Finally,implements the continuous casting 3D simulation training virtual reality system,including hardware gesture input device and 3D simulation software.The hardware device adopts the modular design idea,with high integration,and versatility.The software is developed by the unity3 d game development engine,which has strong three-dimensionality,stable gesture interaction and robust performance to meet practical needs.Figure 36;Table 3;Reference 57...
