[英]error: OpenCV(4.1.2) /io/opencv/modules/imgcodecs/src/loadsave.cpp:715: error: (-215:Assertion failed) !_img.empty() in function 'imwrite'
我正在尝试将图像的一部分保存在边界框中，如下所示：
digit = thresh[x:x+w,y:y+h]
cv2.imwrite(str(c)+'.png',digit)
但是我遇到了以下错误。
error: OpenCV(4.1.2) /io/opencv/modules/imgcodecs/src/loadsave.cpp:715: error: (-215:Assertion failed) !_img.empty() in function 'imwrite'
需要你的帮助。
'x' 或 'y' 超出了我们的 'thresh' 数组的范围 大多数时候它是负值。 解决方案是
x=max(0,x)
y=max(0,y)
