OpenCV Error: Assertion failed (!empty()) in cv::CascadeClassifier::detectMultiScale, file C:\build\master_winpack-bindings-win64-vc14-static\opencv\modules\objdetect\src\cascadedetect.cpp, line 1681

Exception in thread “Thread-2” CvException [org.opencv.core.CvException: cv::Exception: C:\build\master_winpack-bindings-win64-vc14-static\opencv\modules\objdetect\src\cascadedetect.cpp:1681: error: (-215) !empty() in function cv::CascadeClassifier::detectMultiScale

]

解决思路：查看是否为xml路径读取出现错误

解决方法：

public final static String FACE_DETECTOR_XML = “E:/opencv/opencv/sources/data/haarcascades/haarcascades_frontalface_alt.xml”;
