opencv 对象跟踪的边界框定义 [英] Boundingbox defintion for opencv object tracking

问题描述

采用 opencv 的 tracker.init() 函数的 boundingbox 对象是如何定义的?是(xcenter,ycenter,boxwidht,boxheight)或 (xmin,ymin,xmax,ymax)或 (ymin,xmin,ymax,xmax)或者完全不同的东西?

How is the boundingbox object defined that takes opencv's tracker.init() function? is it (xcenter,ycenter,boxwidht,boxheight) or (xmin,ymin,xmax,ymax) or (ymin,xmin,ymax,xmax) or something completely different?

我正在使用 python 和 OpenCV 3.3，我基本上对要为视频的每一帧跟踪的每个对象执行以下操作:

I am using python and OpenCV 3.3 and i basically do the following on each object i want to track for each frame of a video:

tracker = cv2.trackerKCF_create()
ok = tracker.init(previous_frame,bbox)
bbox = tracker.update(current_frame)

推荐答案

答案是:(xmin,ymin,boxwidth,boxheight)
