Root Cause

GOTURN tracker requires a pre-trained model file (prototxt and caffemodel) that is either missing or not loaded correctly.

generic

中文

GOTURN跟踪器需要预训练模型文件（prototxt和caffemodel），这些文件缺失或未正确加载。

Official Documentation

Workarounds

  1. 90% success Download GOTURN model files (goturn.prototxt and goturn.caffemodel) from https://github.com/opencv/opencv_extra/tree/master/testdata/tracking and place them in the current working directory or set OPENCV_GOTURN_MODEL_PATH environment variable. 
    Download GOTURN model files (goturn.prototxt and goturn.caffemodel) from https://github.com/opencv/opencv_extra/tree/master/testdata/tracking and place them in the current working directory or set OPENCV_GOTURN_MODEL_PATH environment variable.
  2. 95% success Use a different tracker (e.g., CSRT or KCF) if GOTURN model download is not feasible. 
    Use a different tracker (e.g., CSRT or KCF) if GOTURN model download is not feasible.

中文步骤

  1. 从https://github.com/opencv/opencv_extra/tree/master/testdata/tracking下载GOTURN模型文件（goturn.prototxt和goturn.caffemodel），放在当前工作目录或设置OPENCV_GOTURN_MODEL_PATH环境变量。
  2. 如果无法下载GOTURN模型，使用其他跟踪器（如CSRT或KCF）。

Dead Ends

Common approaches that don't work:

  1. Reinstalling OpenCV without downloading GOTURN model 90% fail

    GOTURN model is not bundled with OpenCV; must be downloaded separately from opencv_extra or official repository.

  2. Setting cv2.TrackerGOTURN_create() with no arguments 70% fail

    The function does not accept model paths; model must be placed in a specific location or set via environment variable.
