摘要:
伴随着计算机软硬件计算能力的不断提升,增强现实技术的核心算法日益成熟,给人机交互技术及交互方式带来前所未有的突破。 通过对增强现实技术的运动跟踪、环境理解及光线估计等技术进行研究,并采用 ARCore 进行架构和核心方法设计,提出一种移动增强现实应用系统设计方案。 通过对现实场景中的图像或者物体进行运动追踪和定位,计算出虚拟世界与现实世界坐标系的对应关系,采用 ARCore 的网格化技术自动识别表面,捕捉每帧画面的特征点云、锚点、二维平面集合和跟踪状态绘制平面。 利用可识别特征以及设备的朝向和加速度传感器保持实时更新,将虚拟物体按照正确的空间透视关系叠加到现实场景并确定位置,实现可视化仿真及互动教学等功能,系统最终在移动平台进行发布。 增强现实技术以各种形式应用于教学中,具有良好的操作性和交互性,降低了教学实验成本,增加了教学的趣味性。
Abstract:
With the continuous improvement of the computing power of computer software and hardware,the core algorithm of augmented reality technology is becoming more and more mature,which has brought an unprecedented breakthrough? ? ?to human-computer interaction technology and interaction mode. The motion tracking,environment understanding and light estimation of augmented reality technology are studied. ARCore is used to design the architecture and core method. A design scheme of mobile augmented reality application system is proposed. As a result, the corresponding relationship between the coordinate systems of the virtual world and the real one can be calculated by tracking and positioning the motion of the images or objects on the real scene. The surface can be automatically identified using meshing technology of ARCore. The plane is drawn by capturing the feature point cloud,anchor,two-dimensional plane set and tracking state? of each frame. Real time updates are maintained using recognizable features and the orientation and acceleration sensors of the device. And then the virtual objects could be superimposed to the real scene according to the correct spatial perspective relationship before determining the location. All this leads to the functions of visual simulation and interactive teaching. The system is finally released on the mobile platform. Augmented reality technology has been applied to teaching in various forms,with excellent operability and interaction,which reduces the cost of teaching experiment and excites the students’ interest.
