图像上划分网格

---

# 读取图像的python库， 安装方法：pip install pillow
from PIL import Image, ImageDraw
import osfile_dir="C:/Users/Desktop/test_images"
save_dir="C:/Users/Desktop/pic_grid"
if not os.path.exists(save_dir):os.mkdir(save_dir)
for img_name in os.listdir(file_dir):# 定位需要划分的网格大小w_grid = 11 # 宽n个h_grid = 11 # 高n个#定义图像resize的大小w=352h=352 # 读取图像img = Image.open(os.path.join(file_dir,img_name))   
# 可以根据需要是否resizeimg = img.resize((w,h)) 
# 获取图像的宽度和高度width, height = img.size  
# 计算每个方格的宽度和高度cell_width = width // w_gridcell_height = height // h_grid 
# 创建绘图对象draw = ImageDraw.Draw(img)# 绘制水平线for i in range(1, h_grid):y = i * cell_heightdraw.line((0, y, width, y), fill=((int)(255),(int)(0),(int)(0)), width=1)
# 绘制垂直线for j in range(1, w_grid):x = j * cell_widthdraw.line((x, 0, x, height), fill=((int)(255),(int)(0),(int)(0)), width=1)
# 显示图像img.save(os.path.join(save_dir,img_name))#img.show()
