本文实例为大家分享了利用python和OpenCV实现图像拼接,供大家参考,具体内容如下

python+OpenCV实现image stitching

在最新的OpenCV官方文档中可以找到C++版本的Stitcher类的说明, 但是python版本的还没有及时更新, 本篇对python版本的实现做一个简单的介绍.

由于官方文档中还没有python版本的Stitcher类的说明, 因此只能自己去GitHub源码上找, 以下是stitching的样例:

from __future__ import print_function

import cv2 as cv

import numpy as np

import argparse

import sys

modes = (cv.Stitcher_PANORAMA, cv.Stitcher_SCANS)

parser = argparse.ArgumentParser(description='Stitching sample.')

parser.add_argument('--mode',

type = int, choices = modes, default = cv.Stitcher_PANORAMA,

help = 'Determines configuration of stitcher. The default is `PANORAMA` (%d), '

'mode suitable for creating photo panoramas. Option `SCANS` (%d) is suitable '

'for stitching materials under affine transformation, such as scans.' % modes)

parser.add_argument('--output', default = 'result.jpg',

help = 'Resulting image. The default is `result.jpg`.')

parser.add_argument('img', nargs='+', help = 'input images')

args = parser.parse_args()

# read input images

imgs = []

for img_name in args.img:

img = cv.imread(img_name)

if img is None:

print("can't read image " + img_name)

sys.exit(-1)

imgs.append(img)

stitcher = cv.Stitcher.create(args.mode)

status, pano = stitcher.stitch(imgs)

if status != cv.Stitcher_OK:

print("Can't stitch images, error code = %d" % status)

sys.exit(-1)

cv.imwrite(args.output, pano);

print("stitching completed successfully. %s saved!" % args.output)

上面写了一大堆, 然鹅, 直接拿来用的话, 用下面的代码可以了, 简单粗暴

import numpy as np

import cv2

from cv2 import Stitcher

if __name__ == "__main__":

img1 = cv2.imread('1.jpg')

img2 = cv2.imread('2.jpg')

stitcher = cv2.createStitcher(False)

#stitcher = cv2.Stitcher.create(cv2.Stitcher_PANORAMA), 根据不同的OpenCV版本来调用

(_result, pano) = stitcher.stitch((img1, img2))

cv2.imshow('pano',pano)

cv2.waitKey(0)

效果如下:
