在做图像处理时，线阵相机采集保存的图片高度不够，需要将多张图片拼接在一起，原图片大小是2048×1024，需要将三张纵向拼接，形成大小为2048×3072的图片。话不多说，直接上代码
#!usr/bin/python # -*- coding: utf-8 -*- import os from PIL import Image high_size = 1024#高 width_size = 2048#宽 path = 'loulan_1/' #原图片路径 savedpath = 'loulan_2/' #新图片保存路径 imghigh = 3 #三张合并在一起 imagefile = [] i = 0 filelist = os.listdir(path) for item in filelist: i += 1 if(i % 3 != 0): imagefile.append(Image.open(path + item)) else: imagefile.append(Image.open(path + item)) left = 0 right = high_size target = Image.new('RGB',(width_size,high_size*imghigh)) print('ready to save') for image in imagefile: target.paste(image,(0,left,width_size,right)) left += high_size#从上往下拼接，左上角的纵坐标递增 right += high_size#左下角的纵坐标也递增 target.save(savedpath + item ,quality=100) print('save once') print('image of %s have been saved' %(item)) #清空数组 imagefile = []
