摘要:
视觉语言模型在多个领域取得了令人瞩目的成果。然而,由于配对图文数据的稀缺,其在遥感领域的应用仍然受限。为弥合这一差距,合成字幕生成引起了关注,传统上依赖于使用元数据或边界框的基于规则的方法。尽管这些方法提供了一些描述,但往往缺乏捕捉复杂广域场景所需的深度。大型语言模型(LLMs)为生成更具描述性的字幕提供了有前景的替代方案,但可能产生通用输出且易产生幻觉。本文提出一种新方法,通过将地图作为外部数据源集成来增强遥感视觉-语言数据集,从而生成详细且上下文丰富的字幕。此外,我们提出了测量和缓解LLM生成文本中幻觉的方法。我们引入了fMoW-mm,一个融合卫星图像、地图、元数据和文本注释的多模态数据集。我们证明了其在少样本设置下用于自动目标识别的有效性,与其他视觉-语言遥感数据集相比取得了更优的性能。
英文摘要:
Vision language models have achieved impressive results across various fields. However, adoption in remote sensing remains limited, largely due to the scarcity of paired image-text data. To bridge this gap, synthetic caption generation has gained interest, traditionally relying on rule-based methods that use metadata or bounding boxes. While these approaches provide some description, they often lack the depth needed to capture complex wide-area scenes. Large language models (LLMs) offer a promising alternative for generating more descriptive captions, yet they can produce generic outputs and are prone to hallucination. In this paper, we propose a new method to enhance vision-language datasets for remote sensing by integrating maps as external data sources, enabling the generation of detailed, context-rich captions. Additionally, we present methods to measure and mitigate hallucinations in LLM-generated text. We introduce fMoW-mm, a multimodal dataset incorporating satellite imagery, maps, metadata, and text annotations. We demonstrate its effectiveness for automatic target recognition in few-shot settings, achieving superior performance compared to other vision-language remote sensing datasets.
