基于AR技术的造船焊接指示系统构建

Construction of Shipbuilding Welding Indication System Based on AR Technology

针对当前船舶制造行业中出现的焊接作业缺口大、招工难、培训周期较长等问题,借助增强现实技术(AR)实时交互的特点将其应用于船舶焊接作业三维指导中,通过QT中内嵌Open GL进行界面设计和模型重绘,同时利用Open CV比对不同特征提取算法,捕捉真实场景中的人工标识并进行坐标计算与位姿调整,直观地将虚拟模型与焊接工艺信息叠加展示在场景中。仿真结果表明:AR焊接作业指示系统可以有效提高焊接作业的效率,在一定程度上拓展了三维作业指导的形式和造船领域AR技术的应用范畴。

Aiming at the problems of large welding gap,difficult recruitment,and long training period in the current shipbuilding industry,applies Augmented Reality(AR)technology to the three-dimensional guidance of ship welding operations with the help of the characteristics of real-time interaction of AR technology,and uses the embedded OpenGL in QT to interface Design and model redrawing,and use OpenCV to compare different feature extraction algorithms,capture artificial markers in real scenes,perform coordinate calculation and pose adjustment,and intuitively superimpose the virtual model and welding process information in the scene.The simulation results show that the AR welding operation instruction system can effectively improve the efficiency of welding operations,and to a certain extent expand the form of three-dimensional operation guidance and the application scope of AR technology in the field of shipbuilding.
