Abstract

This article presents the development of a vision system designed to enhance the autonomous navigation capabilities of robots in complex forest environments. Leveraging RGBD and thermic cameras, specifically the Intel RealSense 435i and FLIR ADK, the system integrates diverse visual sensors with advanced image processing algorithms. This integration enables robots to make real-time decisions, recognize obstacles, and dynamically adjust their trajectories during operation. The article focuses on the architectural aspects of the system, emphasizing the role of sensors and the formulation of algorithms crucial for ensuring safety during robot navigation in challenging forest terrains. Additionally, the article discusses the training of two datasets specifically tailored to forest environments, aiming to evaluate their impact on autonomous navigation. Tests conducted in real forest conditions affirm the effectiveness of the developed vision system. The results underscore the system's pivotal contribution to the autonomous navigation of robots in forest environments.

摘要

本文提出了一种视觉系统的开发，旨在增强机器人在复杂森林环境中的自主导航能力。该系统利用 RGBD 和热成像摄像机，特别是英特尔 RealSense 435i 和 FLIR ADK，将各种视觉传感器与先进的图像处理算法集成在一起。这种集成使机器人能够实时做出决策，识别障碍物，并在操作过程中动态调整轨迹。本文重点介绍了系统的架构方面，强调了传感器的作用和算法的制定对于确保机器人在具有挑战性的森林地形中安全导航的关键作用。此外，本文还讨论了专门针对森林环境训练的两个数据集，旨在评估它们对自主导航的影响。在真实的森林环境中进行的测试证实了所开发的视觉系统的有效性。结果突出了该系统对机器人在森林环境中自主导航的重要贡献。
