我想创建一个全景使用多个图像。因此,基本上,相机将在平面上线性平移,并将连续拍摄约20-30幅图像。我必须为这些图像创建一个全景图。我尝试过使用缝合功能和传统的方法来查找特征并匹配它们,然后进行翘曲。但我不确定我是否做得很好。我该如何进行
import imutils
import cv2
import glob
input_path = "/Users/akshayacharya/Desktop/Panorama/Raw
Data/riverside/*.jpg"
# input and sort the images
list_images = glob.glob(input_path)
list_sorted = sorted(list_images)
print(list_sorted)
# output path definition
output_path = "/Users/akshayacharya/Desktop/Panorama/Final
Panorama/finalpanoex1.jpg"
# initialize empty list and fill all images
images = []
for image in list_sorted:
image1 = cv2.imread(image)
image1 = cv2.resize(image1, (720, 480))
images.append(image1)
print("Read the images")
# this is the final list to stitch
final = [images[0]]
flag = True
print(len(images))
temp = [images[0]]
print(type(temp))
stitcher = cv2.createStitcher() if imutils.is_cv3() else
cv2.Stitcher_create()
i = 0
while(i < len(images)-1):
(status, stitched) = stitcher.stitch([temp[0], images[i+1]])
if status == 0:
final.append(images[i+1])
print(f"Succesfully stitch {i} to {i+1}")
i = i+1
temp[0] = stitched
continue
if status != 0:
print(f"Succesfully could not stitch {i} to {i + 1}")
for j in range(i+2, len(images)):
print(f"now trying {i} to {j}")
(status, stitchedd) = stitcher.stitch([temp[0], images[j]])
if status == 0:
print(f"Succesfully managed to stitch {i} to {j}")
final.append(images[j])
i=j
temp[0] = stitchedd
break
if status != 0:
print(f"Oops could not stitch {i} to {j}")
print(f"Will now see compatibility between {i} and {j+1}")
continue
i += 1
continue
cv2.imwrite(output_path, temp[0])
