以下是使用SuperGlue进行图像拼接的步骤:
1.安装SuperGlue库
```python
!pip install superglue-cuda102
```
2.导入必要的库
```python
import cv2
import torch
import numpy as np
from superglue import SuperGlue
```
3.加载图像
```python
img1 = cv2.imread('image1.jpg')
img2 = cv2.imread('image2.jpg')
```
4.将图像转换为灰度图像
```python
gray1 = cv2.cvtColor(img1, cv2.COLOR_BGR2GRAY)
gray2 = cv2.cvtColor(img2, cv2.COLOR_BGR2GRAY)
```
5.使用SuperGlue进行特征匹配
```python
# 初始化SuperGlue模型
device = 'cuda' if torch.cuda.is_available() else 'cpu'
model = SuperGlue({'descriptor_dim': 256, 'weights': 'indoor'})
# 提取特征并进行匹配
matches = model({'image0': gray1}, {'image1': gray2})
```
6.绘制匹配结果
```python
# 绘制匹配结果
img_matches = cv2.drawMatches(img1, model.kpts0.cpu().numpy(),
img2, model.kpts1.cpu().numpy(),
matches.matches0.cpu().numpy(),
None, flags=cv2.DrawMatchesFlags_NOT_DRAW_SINGLE_POINTS)
# 显示匹配结果
cv2.imshow('Matches', img_matches)
cv2.waitKey()
```
注意:在使用SuperGlue进行图像拼接时,需要确保两张图像有重叠区域,否则无法进行拼接。
