抽象的。在本文中，我们讨论了使用三维（3-D）图像和虚拟实地考察，教较低水平（即K-14级）的地球科学课程。特别是，3-D PDF可以用来准备学生，或完全取代，实地考察时，后勤问题，使实际旅行太困难，是有效的，或者当一些学生需要一个替代住宿。三维图像可以取代或补充课堂活动，例如从手样品中识别岩石和矿物，或从二维照片和有限的实地观察中识别地质结构。学生还可以参与数据收集和处理，以进一步了解摄影测量和可视化。三维图像的使用可以使教师有更多的时间来涵盖更高级的主题，并向学生传授更多关于科学在地质研究中的作用。我们以新墨西哥州的克里斯托雷伊为例，那里有恐龙的脚印和足迹，但在许多情况下很难看到，而且往往是在许多人难以进入的地方。在这个地点，收集了大约10 000张照片，并将其处理成三维图像，以显示一个大约72平方米的已知足迹区域。然而，我们也对图像进行了一些非常简单的数字处理，使我们能够识别新的足迹和轨迹，这些足迹和轨迹在实地观察时并不明显。这些照片和3D图像已捐赠给拥有化石遗址的Insights博物馆，现在正用于为附近社区开发教育材料和课程。
Abstract. In this paper we discuss the use of three-dimensional (3-D) imagery and virtual field trips to teach lower level (i.e. K-14 level) geoscience courses. In particular, 3-D pdfs can be used to either prepare students for, or completely replace, a field trip when logistical problems make the actual trip too difficult to be effective or when some students need an alternative accommodation. Three dimensional images can replace or supplement classroom activities, such as the identification of rocks and minerals from hand samples or the identification of geologic structures from 2-D photographs and limited field observations. Students can also become involved in data collection and processing to further their understanding of photogrammetry and visualization. The use of 3-D imagery can make additional time available to instructors to cover more advanced topics and teach students more about the role of science in geologic research. We use an example from Cristo Rey, New Mexico, where dinosaur footprints and tracks are present but difficult to see in many cases and often in places that are hard to access for many people. At this site, approximately 10,000 photographs were collected and processed as 3-D images to show one approximately 72 m2 area of known footprints. However, we also conducted some very simple digital manipulations of the images that allowed us to identify new footprints and tracks that were not apparent when viewed in the field. The photographs and 3-D images have been donated to the Insights museum that owns the fossil site and they are now being used to develop educational materials and lessons for the nearby communities.
