动物定位与轨迹追踪对于大脑空间认知和导航神经机制研究具有重要价值,但是传统光学镜头视频定位技术受摄像头视角范围等因素的影响,定位与轨迹追踪的范围有限.针对具有卓越空间认知和导航能力的鸽子,基于灯塔定位技术,提出了一种适用于室内大空间的三维轨迹定位与追踪方法,并给出了相应的定位原理与硬件组成.离体和在体实验研究结果表明,该系统可以在长×宽×高为360 cm × 200 cm × 245 cm空间中对鸽子实现误差厘米级的定位与轨迹追踪.与传统光学镜头视频定位技术相比,该系统具有大空间、高精度、高响应优点,不仅有助于鸽子三维空间认知与导航神经机制的研究,而且对于其他动物的轨迹追踪也具有较高参考价值.
Three-dimensional positioning and trajectory tracking of pigeons in large indoor spaces
Animal localization and trajectory tracking are of great value for the study of brain spatial cognition and navigation neural mechanisms.However,traditional optical lens video positioning techniques are limited in their scope due to factors such as camera perspective.For pigeons with excellent spatial cognition and navigation abilities,based on the beacon positioning technology,a three-dimensional(3D)trajectory positioning and tracking method suitable for large indoor spaces was proposed,and the corresponding positioning principle and hardware structure were provided.The results of in vitro and in vivo experiments showed that the system could achieve centimeter-level positioning and trajectory tracking of pigeons in a space of 360 cm × 200 cm × 245 cm.Compared with traditional optical lens video positioning techniques,this system has the advantages of large space,high precision,and high response speed.It.not only helps to study the neural mechanisms of pigeon 3D spatial cognition and navigation,but also has high reference value for trajectory tracking of other animals.
