3D LiDAR Point Clouds to 2D Floor Plans

APPLANIX是一家总部位于安大略省的公司，开发和制造一系列惯性导航系统产品。ApPlanix的室内移动地图系统(也称为Trimble的室内移动地图解决方案-TIMMS)由ApPlanix于2011年推出，是一款手动操作的推车，旨在精确建模室内空间，而无需访问GPS。目前的系统在将收集的高密度LiDAR点云转换为易于解释的2D平面图方面效率低下，这极大地限制了TIMS在平面图不可用或不可靠的情况下提高应急响应能力和为急救人员做好准备的适用性。为支持正在进行的TIMMS的研究和开发，拟议的研究将调查快速有效的方法，将复杂的3D点云转换为3D楼层平面图，从而提供建筑内部的总体概况，其中楼层平面图可能因缺乏更新而不可用或不可靠。

Applanix is an Ontario based company that develops and manufactures a line of inertial navigation system products. Applanix's indoor mobile mapping system (also known as Trimble's Indoor Mobile Mapping Solution - TIMMS) was introduced in 2011 by Applanix as a manually operated push-cart, designed to accurately model indoor spaces without accessing GPS. The current system is inefficient at converting the collected high density LiDAR point clouds into an easy-to-interpret 2D floor plan, which significantly limits TIMMS applicability for improving emergency responsiveness and preparedness for the first responders in situations where floor plans are unavailable or unreliable. In support of ongoing research and development of TIMMS, the proposed research is to investigate quick and effective methods to translate the complex 3D point clouds into 3D floor plans, thereby providing a general overview of the building interior where floors plans may not be available or unreliable due to the lack of update.
