A proof of concept will be established (in Phase 1), and (in Phase II) a cost-effective portable computer-based system will be developed for acquisition and processing of data needed to create, on-site if desired, as-built drawings of facilities such as buildings and space layouts. Robust algorithms for checking the measurements given and user interface graphics will give the needed reliability for eventual commercial application. The core of the system will be based on a high-performance 32-bit single-board computer readily available. The computer will be supplemented with convenient commercially available transducers for measurement of distances, orientations and specific reference locations. Various options exist for these sensors; a number of particular approaches are discussed, such as an ultrasonic transmitter-receiver, theodolite-type systems with direct electronic readout of angles and distance, and laser-based systems. An overall system with reliable data-acquisition from sensors, real- time processing, analysis and graphical display of the physical location, will be designed to the prototype level in Phase I.

将建立概念验证（在第1阶段），并且（在 第二阶段）将采用成本效益高的便携式计算机系统， 开发用于采集和处理创建所需的数据， 如果需要，现场提供设施（如建筑物）的竣工图 空间布局。 用于检查测量结果的稳健算法 用户界面图形将提供所需的可靠性 用于最终的商业应用。 该系统的核心将是 基于高性能32位单板计算机， available. 计算机将辅以方便的商业 用于测量距离、方向和 具体参考位置。 对于这些，存在各种选项 传感器;讨论了许多特定的方法，例如 超声波发射机-接收机，经纬仪型系统，直接 角度和距离的电子读数，以及基于激光的系统。 整个系统具有来自传感器的可靠数据采集，真实的- 时间处理，分析和图形显示的物理 地点，将在第一阶段设计到原型水平。
