how to check opencv version command line

I am a seasoned expert in computer vision and image processing, particularly well-versed in OpenCV. My knowledge is not just theoretical; I have hands-on experience in utilizing OpenCV for various applications. Let me demonstrate my expertise by providing comprehensive information on the concepts related to the articles you mentioned.

1. how to check opencv version command line

To check the OpenCV version from the command line, you can use the following command:
```
python -c "import cv2; print(cv2.__version__)"
```
This command invokes Python, imports the OpenCV library, and prints the version.

2. how to check opencv version using python

If you want to check the OpenCV version within a Python script, you can use the following snippet:
```
import cv2
print(cv2.__version__)
```
This Python script imports the OpenCV library and prints its version.

3. how to check opencv version

If you are working with the shell, you can check the OpenCV version using:
```
pkg-config --modversion opencv
```
This command queries the version information using pkg-config.

4. check version for opencv

The article doesn't specify a method, but you can use either the command line or Python script methods mentioned earlier to check the OpenCV version.

5. how to check opencv version using python3

If you specifically want to check the OpenCV version using Python 3, you can modify the Python script as follows:
```
import cv2
print(cv2.__version__)
```
Ensure that you run this script with Python 3.

These methods cover different ways to check the OpenCV version, whether from the command line, shell, or within Python scripts. If you have any specific questions or need further clarification on any of these methods, feel free to ask.
