Airborne video has demonstrated promise as a rapid, low-cost means of acquiring imagery for a variety of ecological applications: fish and wildlife habitat, plant communities, phytomass determination, crop damage, weed infestations. Image acquisition can be timed to coincide with an event of interest (e.g., a flood, an algae bloom) at a spatial scale suitable for detecting objects as small as individual organisms (e.g., trees, geese). The benefits of airborne video could be greatly enhanced, however, by combining frame-grabbed video images into a comprehensive geo-referenced database suitable for use in a Geographic Information System (GIS) where the information could be integrated with other spatial databases (e.g., population density, land ownership) and manipulated using the multitude of spatial analysis tools inherent to GISs. Therefore, the goal of this award is to develop a prototype airborne video database acquisition system capable of: 1) gathering all the information needed to georeference a video image at the moment of acquisition, 2) displaying in real time the spatial extent and location of images acquired, and 3) selecting images for analysis and mosaicing them into a comprehensive GIS coverage.

机载视频已被证明是一种快速、低成本的 获取各种生态图像的方法 应用：鱼类和野生动物栖息地，植物群落， 植物量测定、作物损害、杂草侵扰。 图像 采集可以被定时以与感兴趣的事件一致 (e.g.,洪水，藻类水华）的空间尺度， 检测小到单个生物体的对象（例如，树木， 鹅）。 机载视频的好处可以大大 然而，通过将帧抓取的视频图像组合成 综合地理参照数据库，适用于 地理信息系统（GIS），其中的信息可以 与其他空间数据库集成（例如，人口 密度，土地所有权）和操纵使用的众多 GIS固有的空间分析工具。 因此，目标 该奖项是开发一个原型机载视频数据库， 采集系统能够：1）收集所有信息 需要对视频图像进行地理配准， 采集，2）真实的时间显示空间范围，以及 获取的图像的位置，以及3）选择用于分析的图像 并将其镶嵌成一个全面的地理信息系统覆盖范围。
