使用Java时cornerSubPix错误“（--215：断言失败）计数> = 0”

Question

我的环境是macos，java，opencv 4.1.2，intellij等... 我的代码是：

    goodFeaturesToTrack(basedImg,corners,20,0.1,10,maskMat,3,false,0.04);
TermCriteria termCriteria = new TermCriteria(TermCriteria.MAX_ITER+TermCriteria.COUNT,1,0.001);
    Imgproc.cornerSubPix(basedImg,corners,new Size(5,5),new Size(-1,-1),termCriteria);

它引发错误：

Exception in thread "main" CvException [org.opencv.core.CvException: cv::Exception: OpenCV(4.1.2-pre) /Users/friends/opencv/modules/imgproc/src/cornersubpix.cpp:58: error: (-215:Assertion failed) count >= 0 in function 'cornerSubPix'

如何纠正？ “错误：（-215：断言失败）计数> = 0”是什么意思？
