使用opencv-python在图片上显示中文

测试图像如下：

 

核心代码如下：

import cv2
import numpy as np
from PIL import Image, ImageDraw, ImageFont
 
def cv2ImgAddText(img, text, left, top, textColor=(0, 255, 0), textSize=20):
    if (isinstance(img, np.ndarray)):  #判断是否OpenCV图片类型
        img = Image.fromarray(cv2.cvtColor(img, cv2.COLOR_BGR2RGB))
    draw = ImageDraw.Draw(img)
    fontText = ImageFont.truetype("font/simsun.ttc", textSize, encoding="utf-8")
    draw.text((left, top), text, textColor, font=fontText)
    return cv2.cvtColor(np.asarray(img), cv2.COLOR_RGB2BGR)
img = cv2.imread('1.png')    
img = cv2ImgAddText(img, "檢測結果!", 140, 200, (255, 0, 0), 20)
cv2.imshow("print chinese to image",img) 
cv2.imwrite('03.jpg',img) 
cv2.waitKey()
cv2.destroyAllWindows()

运行后显示及保存的结果如下：
