opencv目标追踪CSRT_opencvcsrt

import cv2
 
cap = cv2.VideoCapture(0)
 
ret, frame = cap.read()
 
bbox = cv2.selectROI('frame', frame, fromCenter=False, showCrosshair=True)
track = cv2.legacy.TrackerCSRT_create()
 
track.init(frame, bbox)
while True:
    _, frame = cap.read()
    ok, box = track.update(frame)
 
    if ok:
        (x, y, w, h) = [int(i) for i in box]
        cv2.rectangle(frame, pt1=(x, y), pt2=(x+w, y+h), color=(0, 255, 0), thickness=2)
 
    cv2.imshow('frame', frame)
 
    if cv2.waitKey(1) == 27:
        break
 
cap.release()
cv2.destroyAllWindows()

运行代码，在当前界面中截取一roi，敲下回车或者空格，持续运行，esc推出，感觉效果还是可以的。

报错：

module 'cv2' has no attribute 'legacy'

解决方法

pip uninstall opencv-python
pip install opencv-contrib-python --user

安装完再次运行即可
