Exploring Emerging Trends and Research Opportunities in Visual Place Recognition
- 结合视觉与文本信息的图文模型用于环境识别
- 在复杂场景下实现更高精度与鲁棒性定位
- 适合从事SLAM、机器人导航的研究者参考
基于视觉的识别，如图像分类、目标检测等，是计算机视觉与机器人领域长期面临的挑战。对机器人而言，环境知识是执行复杂导航任务的前提，视觉位置识别对于大多数定位、重定位及同时定位与地图构建（SLAM）中的回环检测流程至关重要。具体而言，它对应系统利用计算机视觉工具识别并匹配此前访问过的位置的能力。为开发更精准、更鲁棒的新技术，受自然语言处理方法成功的启发，研究人员近期将注意力转向视觉-语言模型，该模型整合了视觉与文本数据。
原文摘要 · Abstract (English)
Visual-based recognition, e.g., image classification, object detection, etc., is a long-standing challenge in computer vision and robotics communities. Concerning the roboticists, since the knowledge of the environment is a prerequisite for complex navigation tasks, visual place recognition is vital for most localization implementations or re-localization and loop closure detection pipelines within simultaneous localization and mapping (SLAM). More specifically, it corresponds to the system's ability to identify and match a previously visited location using computer vision tools. Towards developing novel techniques with enhanced accuracy and robustness, while motivated by the success presented in natural language processing methods, researchers have recently turned their attention to vision-language models, which integrate visual and textual data.
