SBIR Phase I: Rapid Generation of High-Resolution, Geographically Registered, 3D Terrain Models

这一小型企业创新研究(SBIR)第一阶段项目的目标是改进创建、更新和利用地理信息系统(GIS)数据库的方式。将建立软件系统，使用户能够快速、廉价地从各种航空和卫星平台收集的数字图像中生成、更新、分析和可视化高分辨率3D数字地形模型。将采用综合办法，考虑到地形建模过程的所有方面，开发软件工具，将从新的高分辨率数字成像传感器和低成本导航仪器收集的原始数据转换为高分辨率、按地理位置登记的三维地形模型。这些产品的低成本和较短的周转时间将使政府和商业机构能够扩大其地理信息系统的应用范围，特别是在环境监测、变化检测和城市规划领域。

The goal of this Small Business Innovation Research (SBIR) Phase I project is to improve the way in which Geographic Information System (GIS) databases are created, updated and utilized. Software systems will be built that enable users to rapidly and inexpensively generate, update, analyze and visualize high-resolution 3D digital terrain models from digital images collected by a wide range of aerial and satellite platforms. Using an integrated approach that takes into account all aspects of the terrain modeling process, software tools will be developed that transform raw data collected from new high-resolution digital imaging sensors and low-cost navigation instruments into high-resolution, geographically registered 3D terrain models. The low cost and short turnaround time for these products will enable government and commercial organizations to expand the scope of their GIS applications, especially in the areas of environmental monitoring, change detection, and urban planning.
