- 采用UWB DWM1001C传感器佩戴式定位，实现高精度追踪
- 视距下定位误差<5毫米，非视距下<50毫米
- 适合需要精准运动轨迹的神经行为学研究
啮齿类动物长期作为行为研究的首选模型，传统笼养环境常限制其自然行为表现。精确追踪动物运动是行为研究的关键，但传统视频追踪对夜行性动物存在局限。本研究引入超宽带（UWB）传感器技术，开发新型定位系统：将UWB DWM1001C传感器集成于定制佩戴装置，用于单只大鼠追踪。在4×2英尺的简化实验环境中评估性能。结果表明，在视距（LoS）条件下定位误差小于5毫米，非视距（NLoS）条件下小于50毫米。该研究为动物定位提供了更精确可靠的方法，展示了UWB技术在提升行为研究精度方面的潜力。
原文摘要 · Abstract (English)
Rodents have long been established as the premier model for behavioral studies, traditionally raised and maintained in conventional cage environments. However, these settings often limit rodents' ability to exhibit their full range of intrinsic behaviors and natural interactions. Precise tracking of animal movement is a critical component in behavioral research, but traditional methods, such as video tracking, present challenges, particularly with nocturnal species like rodents. This study introduces the application of ultra-wideband (UWB) sensor technology to develop a novel tracking system. The UWB DWM1001C sensor was integrated into a custom-made device worn by a single rat. A simplified habitat, measuring four-by-two feet, was used to evaluate system performance. The results show positioning accuracy errors of less than five millimeters for line-of-sight (LoS) and less than 50 millimeters for non-line-of-sight (NLoS) scenarios. This research provides a more accurate and reliable approach for animal localization, showcasing the potential of UWB sensor technology in enhancing precision in behavioral studies.
