error: OpenCV(4.5.4) : -1: error: (-5:Bad argument) in function ‘add’
Expected Ptr＜cv::legacy::Tracker＞ for argument ‘newTracker‘
遇到的问题
error: OpenCV(4.5.4) : -1: error: (-5:Bad argument) in function ‘add’
Overload resolution failed:
- Expected Ptrcv::legacy::Tracker for argument 'newTracker'
- Expected Ptrcv::legacy::Tracker for argument 'newTracker'
原因分析
OpenCV官方API变化，导致接口不通用，需要注意其接口的变化，强烈建议去阅读官方文档！！！
解决方案
opencv(4.5.4)目标追踪函数应用时,首先需要在MultiTracker_create前加legacy,为cv2.legacy.MultiTracker_create,同时在创建追踪算法时也需要加上legacy,如cv2.legacy.TrackerKCF_create()
