Inteligencia artificial para la multi-clasificación de fauna en fotografías automáticas utilizadas en investigación científica

  • 构建神经网络模型自动分类相机陷阱图像中的动物
  • 可处理海量图像,解决人工标注效率低的问题
  • 适合生态学家、保护生物学家和环境管理者使用

自然环境管理(如保护或生产)需要深入了解野生动物。动物数量、位置和行为是生态与野生动物研究的核心内容。相机陷阱能快速收集大量野生动物在自然栖息地的照片,避免人为干扰。在阿根廷火地岛,研究人员正利用相机陷阱分析不同草食动物(羊驼、牛、羊)的森林利用情况,以优化管理并保护生态系统。尽管相机陷阱可生成数百万张图像,但人工解读面临可扩展性挑战,导致大量数据未被充分利用。人工智能中的神经网络与深度学习在过去十年中显著推动了全球图像识别发展。将这些技术应用于生态研究,可从相机陷阱照片中提取关键信息,深化对自然过程的理解,并提升野生区域管理水平。本项目旨在开发神经网络模型,实现相机陷阱图像中动物物种的自动分类,应对科学研究中的大规模数据挑战。

原文摘要 · Abstract (English)

The management of natural environments, whether for conservation or production, requires a deep understanding of wildlife. The number, location, and behavior of wild animals are among the main subjects of study in ecology and wildlife research. The use of camera traps offers the opportunity to quickly collect large quantities of photographs that capture wildlife in its natural habitat, avoiding factors that could alter their behavior. In Tierra del Fuego, Argentina, research is being conducted on forest use by different herbivores (guanacos, cows, sheep) to optimize management and protect these natural ecosystems. Although camera traps allow for the collection of millions of images, interpreting such photographs presents a scalability challenge for manual processing. As a result, much of the valuable knowledge stored in these vast data repositories remains untapped. Neural Networks and Deep Learning are areas of study within Artificial Intelligence. Over the past decade, these two disciplines have made significant contributions to image recognition on a global scale. Ecological and wildlife conservation studies can be combined with these new technologies to extract important information from the photographs obtained by camera traps, contributing to the understanding of various natural processes and improving the management of the involved wild areas. Our project aims to develop neural network models to classify animal species in photographs taken with camera traps, addressing large-scale challenges in scientific research.
