The Polar Sea Ice Topography REconstruction System, or PSITRES, is a 3D camera system designed to continuously monitor an area of ice and water adjacent to an ice-going vessel. Camera systems aboard ships in the polar regions are common; however, the application of computer vision techniques to extract high-level information from the imagery is infrequent. Many of the existing systems are built for human involvement throughout the process and lack automation necessary for round the clock use. The PSITRES was designed with computer vision in mind. It can capture images continuously for days on end with limited oversight. We have applied the system in different ice observing scenarios. The PSITRES was deployed on three research expeditions in the Arctic and Subarctic, and we present applications in measuring ice concentration, melt pond fraction and presence of algae. Systems like PSITRES and the computer vision algorithms applied represent steps toward automatically observing, evaluating and analyzing ice and the environment around ships in ice-covered waters.

极地海冰地形重建系统

极地海冰地形重建系统 (PSITRES) 是一种 3D 摄像系统，旨在连续监测冰船附近的冰水区域。极地地区船上的摄像系统很常见；然而，应用计算机视觉技术从图像中提取高级信息的情况并不常见。许多现有系统都是为整个过程中的人工参与而构建的，并且缺乏全天候使用所需的自动化。PSITRES 的设计考虑了计算机视觉。它可以在有限的监督下连续几天连续捕获图像。我们已经将该系统应用于不同的冰观测场景。PSITRES 被部署在北极和亚北极的三个研究考察中，我们展示了测量冰浓度的应用，熔池分数和藻类的存在。PSITRES 等系统和所应用的计算机视觉算法代表了在冰雪覆盖的水域中自动观察、评估和分析冰和船舶周围环境的步骤。
