OpenCV Createsamples ROI断言失败错误排查求助

执行命令 #

在VS Code终端执行以下命令：

C:\Ankit\VirEnv\opencv\build\x64\vc14\bin\opencv_createsamples.exe -info C:\Ankit\VirEnv\pos.txt  -w 20 -h 20 -num 1000 -vec pos.vec

相关文件说明 #

pos.txt文件通过opencv_annotation工具生成，包含标注的目标边界框坐标。

命令执行输出 #

最终错误信息 #

OpenCV(3.4.16) Error: Assertion failed (0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows) in cv::Mat::Mat, file C:\build\3_4_winpack-build-win64-vc14\opencv\modules\core\src\matrix.cpp, line 751 

问题描述 #

我通过opencv_annotation工具生成的pos.txt应该包含正确的边界框坐标，但执行命令后仍触发上述错误。已参考相关视频教程和OpenCV官方文档，无法定位问题原因。
