visual parameters during tiger beetle prey pursuit

Contains frame-by-frame data of visual parameters experienced by a tiger beetle when chasing a prey dummy. Variables were calculated from coordinates determined in each video frame, and smoothed using a 3-frame moving average. "Open" and "close" columns indicate frames where jaw opening/closing begins, with a lag of 0 to 20 frames before that event.本数据集收录了虎甲（tiger beetle）追逐仿真猎物时的逐帧视觉参数数据。所有变量均由各视频帧中提取的坐标计算得到，并通过3帧移动平均法完成平滑处理。"Open"与"close"两列分别标注颚部开合动作起始的帧，该标注与实际事件间存在0至20帧的滞后时长。
