我们提出了分析和实证调查的最佳摄像机角度用于基于光流的定心响应。这种技术通常用于引导地面和空中机器人在障碍物之间移动。过去研究人员已经实现了各种摄像机角度，但令人惊讶的是，很少提到这些摄像机角度选择的动机，也没有对最佳摄像机角度进行调查。我们的研究表明，摄像机的角度起着关键作用的控制策略的性能为中心的反应，经验和分析研究表明，最佳的摄像机角度为45度时，平行障碍物之间的旅行
We present analytical and empirical investigations into the optimum camera angle to use for the optic flow-based centering response. This technique is commonly used to guide both ground-based and aerial robots between obstacles. A variety of camera angles have been implemented by researchers in the past, but surprisingly little mention is made of the motivation for these camera angle choices, nor has an investigation into the optimum camera angle been conducted. Our investigation shows that camera angle plays a key role in the performance of control strategies for the centering response, and both empirical and analytical investigations show the optimum camera angle to be 45 degrees when traveling between parallel obstacles
