摘要
研究利用AR技术对现实世界距离进行测量,提出搭载激光雷达扫描仪的移动设备AR测量方案,创新性的结合激光即时定位与地图构建(SLAM)技术,并基于ARKit工具包构建增强现实测量应用。应用在搭载激光雷达扫描仪的iPad Pro上测试运行,并分别在水平平面、垂直平面和空间任意点等场景中进行测量实验,实验结果表明,测量距离相对误差接近1.5%,达到测量应用的精度要求,并高于同类测量应用。因此,搭载激光雷达扫描仪的AR测量应用较其他同类测量应用相比,具有适用测量场景更广泛、准确性更高的优势。
Research the use of AR technology to measure distances in the real world, and propose an AR measurement solution for mobile devices equipped with lidar scanners, innovatively combining laser instantaneous localization and mapping(SLAM) technology, and build based on the ARKit toolkit augmented reality measurement application. The application was tested and run on an iPad Pro equipped with a lidar scanner, and measurement experiments were carried out in the horizontal plane, vertical plane, and any point in space. The experimental results show that the relative error of the measurement distance is close to 1.5%, reaching the accuracy of the measurement application requirements, and higher than similar measurement applications. Therefore, compared with other similar measurement applications, AR measurement applications equipped with lidar scanners have the advantages of wider applicable measurement scenarios and higher accuracy.
