对python opencv 添加文字 cv2.putText 的各参数介绍

如下所示：

cv2.putText(img, str(i), (123,456)), font, 2, (0,255,0), 3)

各参数依次是：图片，添加的文字，左上角坐标，字体，字体大小，颜色，字体粗细

其中字体可以选择

FONT_HERSHEY_SIMPLEX Python: cv.FONT_HERSHEY_SIMPLEX normal size sans-serif font

FONT_HERSHEY_PLAIN Python: cv.FONT_HERSHEY_PLAIN small size sans-serif font

FONT_HERSHEY_DUPLEX Python: cv.FONT_HERSHEY_DUPLEX normal size sans-serif font (more complex than FONT_HERSHEY_SIMPLEX)

FONT_HERSHEY_COMPLEX Python: cv.FONT_HERSHEY_COMPLEX normal size serif font

FONT_HERSHEY_TRIPLEX Python: cv.FONT_HERSHEY_TRIPLEX normal size serif font (more complex than FONT_HERSHEY_COMPLEX)

FONT_HERSHEY_COMPLEX_SMALL Python: cv.FONT_HERSHEY_COMPLEX_SMALL smaller version of FONT_HERSHEY_COMPLEX

FONT_HERSHEY_SCRIPT_SIMPLEX Python: cv.FONT_HERSHEY_SCRIPT_SIMPLEX hand-writing style font

FONT_HERSHEY_SCRIPT_COMPLEX Python: cv.FONT_HERSHEY_SCRIPT_COMPLEX more complex variant of FONT_HERSHEY_SCRIPT_SIMPLEX

FONT_ITALIC Python: cv.FONT_ITALIC flag for italic font

字体大小，数值越大，字体越大

字体粗细，越大越粗，数值表示线占有直径像素个数

void cv::putText(
 InputOutputArray img,
 const String & text,
 Point org,
 int fontFace,
 double fontScale,
 Scalar color,
 int thickness = 1,
 int lineType = LINE_8,
 bool bottomLeftOrigin = false 
) 
Python:
img =cv.putText(img, text, org, fontFace,fontScale, color[, thickness[, lineType[, bottomLeftOrigin]]])
