putText(img, text, org, fontFace, fontScale, color, thickness=None, lineType=None, bottomLeftOrigin=None)

import cv2

#加载背景图片
bk_img = cv2.imread("background.jpg")
#在图片上添加文字信息
cv2.putText(bk_img,"Hello World", (100,300), cv2.FONT_HERSHEY_SIMPLEX, 
0.7,(255,255,255), 1, cv2.LINE_AA)
#显示图片
cv2.imshow("add_text",bk_img)
cv2.waitKey()
#保存图片
cv2.imwrite("add_text.jpg",bk_img)

import cv2
from PIL import ImageFont, ImageDraw, Image
import numpy as np

bk_img = cv2.imread("background.jpg")
#设置需要显示的字体
fontpath = "font/simsun.ttc"
font = ImageFont.truetype(fontpath, 32)
img_pil = Image.fromarray(bk_img)
draw = ImageDraw.Draw(img_pil)
#绘制文字信息
draw.text((100, 300),  "Hello World", font = font, fill = (255, 255, 255))
draw.text((100, 350),  "你好", font = font, fill = (255, 255, 255))
bk_img = np.array(img_pil)

cv2.imshow("add_text",bk_img)
cv2.waitKey()
cv2.imwrite("add_text.jpg",bk_img)
