你可以使用以下步骤将 VGG 打标的 JSON 文件与 OpenCV 结合起来,在原始图像上显示标记:
1. 在 Python 中导入必要的库:
```python
import cv2
import json
```
2. 加载原始图像和 VGG 打标的 JSON 文件:
```python
img = cv2.imread('path/to/image.jpg')
with open('path/to/vgg_file.json', 'r') as f:
labels = json.load(f)
```
3. 将标记循环遍历并将其绘制在原始图像上:
```python
for label in labels:
x, y, w, h = label['x'], label['y'], label['width'], label['height']
cv2.rectangle(img, (x, y), (x + w, y + h), (0, 255, 0), 2)
cv2.putText(img, label['label'], (x, y - 10), cv2.FONT_HERSHEY_SIMPLEX, 0.9, (0, 255, 0), 2)
```
4. 最后,使用 OpenCV 显示带有标记的原始图像:
```python
cv2.imshow('Image with Labels', img)
cv2.waitKey(0)
cv2.destroyAllWindows()
```
这应该可以让您在原始图像上显示 VGG 打标的 JSON 文件中的标记。
