In this article, we present an accurate and easy to use augmented reality (AR) application for mobile devices. In addition, we show how to better organize and track artifacts using augmented reality for museum employees using both the mobile device and a 3D graphic model of the museum in a PC server. The AR mobile application can connect to the server, which maintains the status of artifacts including its 3D location and respective room location. The system relies on 3D measurements of the rooms in the museum as well as coordinates of the artifacts and reference markers in the respective rooms. The measured coordinates of the artifacts through the AR mobile application are stored in the server and displayed at the corresponding location of the 3D rendered representation of the room. The mobile application allows museum managers to add, remove, or modify artifacts' locations simply by touching the desired location on the touch screen showing live video with AR overlay. Therefore, the accuracy of the touch screen-based artifact positioning is very important. The accuracy of the proposed technique is validated by evaluating angular error measurements with respect to horizontal and vertical field of views that are 60∘ and 47∘, respectively. The worst-case angular errors in our test environment exhibited 0.60∘ for horizontal and 0.29∘ for vertical, which is calculated to be well within the error due to touch screen sensing accuracy.

基于增强现实的博物馆实时精准文物管理系统

在本文中,我们为移动设备提供了一种准确且易于使用的增强现实 (AR) 应用程序。此外,我们展示了如何使用增强现实技术为博物馆员工使用移动设备和 PC 服务器中博物馆的 3D 图形模型更好地组织和跟踪文物。AR 移动应用程序可以连接到服务器,服务器维护工件的状态,包括其 3D 位置和各自的房间位置。该系统依赖于博物馆房间的 3D 测量以及各个房间中文物和参考标记的坐标。通过 AR 移动应用程序测量的工件坐标存储在服务器中,并显示在房间的 3D 渲染表示的相应位置。移动应用程序允许博物馆管理者添加、删除、或通过触摸显示带有 AR 叠加的实时视频的触摸屏上的所需位置来修改工件的位置。因此,基于触摸屏的伪像定位的准确性非常重要。通过评估相对于水平和垂直视场分别为 60∘ 和 47∘ 的角度误差测量,验证了所提出技术的准确性。在我们的测试环境中,最坏情况下的角度误差在水平方向为 0.60∘,在垂直方向为 0.29∘,由于触摸屏感应精度,计算结果完全在误差范围内。通过评估相对于水平和垂直视场分别为 60∘ 和 47∘ 的角度误差测量,验证了所提出技术的准确性。在我们的测试环境中,最坏情况下的角度误差在水平方向为 0.60∘,在垂直方向为 0.29∘,由于触摸屏感应精度,计算结果完全在误差范围内。通过评估相对于水平和垂直视场分别为 60∘ 和 47∘ 的角度误差测量,验证了所提出技术的准确性。在我们的测试环境中,最坏情况下的角度误差在水平方向为 0.60∘,在垂直方向为 0.29∘,由于触摸屏感应精度,计算结果完全在误差范围内。
