提出并论证了一种基于运动容限的可见光身份证空间分布提取方法。由无人机观察可见光ID，并且通过处理补偿可见光ID发射器与其观察者之间的相对运动的图像序列来提取ID信号的特征。即使当安装在无人机上的图像传感器的ID信号速率和帧速率不高到足以忽略运动时，也减轻了空间分布的可见光ID的估计精度的运动引起的劣化。所提出的方法潜在地提高了灾难后机器人救援的鲁棒性。
A motion-tolerant method for extracting spatial distribution of visible light IDs is proposed and demonstrated. A visible light ID is observed by a flying drone, and a feature of the ID signal is extracted by processing an image sequence which compensates relative motion between visible light ID emitters and its observer. Motion-induced degradation of estimation accuracy of spatially distributed visible light IDs is mitigated even when the ID signal rate and frame rate of an image sensor mounted on the drone are not high enough to neglect the motion. The proposed method potentially improves robustness of robotic rescues after disasters.
