通过仿真训练智能感知系统,提升水下机器人在浑浊环境中的成像质量。

Learning Underwater Active Perception in Simulation

  • 用MLP预测不同距离和光照下的图像质量,指导机器人主动调整姿态。
  • 在10种不同浑浊度的水体中测试,图像质量显著优于传统方法。
  • 专为水下光传播建模优化的仿真数据,适合水下视觉研究者使用。

在水下机器人自主检测设施时,水体状况对能见度有显著影响,浑浊度会阻碍结构的准确成像。现有方法虽能应对浑浊和后向散射,但存在运动与配置限制。本文提出一种高效主动感知框架:利用多层感知机(MLP)根据目标距离和人工光源强度预测图像质量。我们基于Blender修改的建模软件生成包含10种不同浑浊度与后向散射水平的合成数据集。在仿真中验证表明,该方法相比传统手段显著提升了视觉覆盖范围与图像质量。项目代码已公开于https://roboticimaging.org/Projects/ActiveUW/。

原文摘要 · Abstract (English)

When employing underwater vehicles for the autonomous inspection of assets, it is crucial to consider and assess the water conditions. These conditions significantly impact visibility and directly affect robotic operations. Turbidity can jeopardise the mission by preventing accurate visual documentation of inspected structures. Previous works have introduced methods to adapt to turbidity and backscattering, however, they also include manoeuvring and setup constraints. We propose a simple yet efficient approach to enable high-quality image acquisition of assets in a broad range of water conditions. This active perception framework includes a multi-layer perceptron (MLP) trained to predict image quality given a distance to a target and artificial light intensity. We generate a large synthetic dataset that includes ten water types with varying levels of turbidity and backscattering. For this, we modified the modelling software Blender to better account for the underwater light propagation properties. We validated the approach in simulation and demonstrate significant improvements in visual coverage and image quality compared to traditional methods. The project code is available on our project page at https://roboticimaging.org/Projects/ActiveUW/.
