Research On Virtual Trajectory Rendering Algorithm And Software System Development For Industrial Robot

With the development of information technology and the continuous promotion of "industrial Internet",many industrial powers in the world have launched the manufacturing development plan,and China has also put forward the "made in China 2025 plan".At present,China’s three-dimensional visualization technology has been in the fourth development stage from research to application.The development of robot technology is the focus of today’s mechanical and electronic technology.In the context of the upgrading and transformation of China’s manufacturing industry,"machinery replacing labor" is the general trend.Industrial robot has the advantages of high efficiency,high precision and small error.It can replace manual work in bad environment.At present,it has been used in handling,spraying,welding and other fields.In the epidemic environment,industrial robots play an indispensable role in various fields.Virtual reality technology is the focus of research in recent years.By means of modern information means such as 3D modeling and transmission protocol,creating a mirror virtual model one-to-one corresponding to the actual space in the virtual space can help the manufacturing factory realize three-dimensional visualization,management and production automation of process,and achieve the purpose of improving work efficiency,reducing development cost,safe production and blocking loopholes.Augmented reality technology strengthens the interaction with virtual information on the basis of virtual reality technology,so it requires higher accuracy and faster speed for picture rendering.Aiming at this demand,this paper optimizes the relevant algorithms of robot virtual trajectory,and develops an industrial oriented 3D visualization application.The specific contents are as follows:(1)According to the high-precision rendering requirements of the robot trajectory on the browser page,the curve interpolation and fitting optimization of the robot trajectory is carried out based on the data collected by the sensor,and an algorithm optimization method based on GPU parallel computing is proposed,which effectively reduces the computing load of the software system in large-scale scenes,optimizes the virtual trajectory of the robot in visualization applications,makes it smooth and brings users a more smooth viewing experience.(2)According to the high-precision rendering requirements of the robot trajectory on the browser page,the curve interpolation and fitting optimization of the robot trajectory is carried out based on the data collected by the sensor,and an algorithm optimization method based on GPU parallel computing is proposed,which effectively reduces the computing load of the software system in large-scale scenes,optimizes the virtual trajectory of the robot in visualization applications,makes it smooth and brings users a more smooth viewing experience.(3)The industrial 3D visualization software system based on webgl is realized.The system has light volume and good visualization effect.On this basis,the underlying interface module of webgl is rewritten,and the above optimization algorithm is applied to the system to solve the problem of limited rendering performance of webgl.The system has the functions of human-computer interaction,animation display,information panel,realtime alarm and so on,which is convenient for enterprises to realize manufacturing automation and reduce labor time cost,It provides a reference for lightweight web applications.
