摘要:

本文研究了一种有效的跟踪动态目标的轨迹生成方法,该方法结合了可探测性目标。所提出的方法主动地引导电影摄影师无人机的运动,使得目标的颜色与无人机的视图中的背景的颜色很好地区分开。针对这个目标,我们定义了一个颜色可检测性的度量,在计算一个离散的路径优化的度量后,我们生成一个动态可行的轨迹。整个流水线可以即时更新以响应目标的运动。为了有效的离散路径生成,我们构建了一个有向无环图(DAG),拓扑排序可以确定分析没有深度优先搜索。在二次规划(QP)框架下获得了光滑路径。我们验证了增强性能的最先进的目标检测和跟踪算法时,摄像机无人机执行的轨迹从所提出的方法。

英文摘要:

This work investigates an efficient trajectory generation for chasing a dynamic target, which incorporates the detectability objective. The proposed method actively guides the motion of a cinematographer drone so that the color of a target is well-distinguished against the colors of the background in the view of the drone. For the objective, we define a measure of color detectability given a chasing path. After computing a discrete path optimized for the metric, we generate a dynamically feasible trajectory. The whole pipeline can be updated on-the-fly to respond to the motion of the target. For the efficient discrete path generation, we construct a directed acyclic graph (DAG) for which a topological sorting can be determined analytically without the depth-first search. The smooth path is obtained in quadratic programming (QP) framework. We validate the enhanced performance of state-of-the-art object detection and tracking algorithms when the camera drone executes the trajectory obtained from the proposed method.
