使用cv2.putText()绘制文字默认不支持中文,我们使用PIL库来写中文,代码如下: 代码语言:javascript 复制 #-*-coding:utf-8-*-importcv2import numpyasnpfromPILimportImage,ImageDraw,ImageFont defcv2ImgAddText(img,text,left,top,textColor=(0,255,0),textSize=20):if(isinstance(img,np.ndarray)):#判断是否...
python opencv3 给图片加中文 转自:https://www.cnblogs.com/arkenstone/p/6961453.html opencv3.2将中文输出到图片上 opencv自带的putText函数无法输出utf8类型的字符,因此无法将中文打印到图片上。用这篇文章的freetype可以实现中文输出,但是需要将字符解码转码比较麻烦,而Pillow的Image函数输出中文则相对容易些,因此...
In this tutorial we will learn how to draw text on an image, using Python and OpenCV. The code we will analyze was tested on Windows 8.1, with version 4.1.2 of OpenCV. The Python version used was 3.7.2. How to draw text on the image We will start by importing the cv2 module, whi...
