本文例項為大家分享了利用python和OpenCV實現影象拼接,供大家參考,具體內容如下
python+OpenCV實現image stitching
在最新的OpenCV官方文件中可以找到C++版本的Stitcher類的說明,但是python版本的還沒有及時更新,本篇對python版本的實現做一個簡單的介紹.
由於官方文件中還沒有python版本的Stitcher類的說明,因此只能自己去GitHub原始碼上找,以下是stitching的樣例:
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)
上面寫了一大堆,然鵝,直接拿來用的話,用下面的程式碼可以了,簡單粗暴
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),根據不同的OpenCV版本來呼叫 (_result,pano) = stitcher.stitch((img1,img2)) cv2.imshow('pano',pano) cv2.waitKey(0)
效果如下:
