The function in this package is for checking the current camera parameters. An ideal camera will have a constant ratio between the real distance and pixel distance. The fuction contained in this package could also telling the ratio under known environment.
- Add your picture path to the code and modify the scaling percentage for convinence.
- Run the python program.
- Input the real distance in cmd/terminal used.
- Click on the 4 out most corner dots' center for perspective transformation calculation.
Dot Sequence Matters, please follow the steps below.
- Click on 2 horizontal or vertical adjacent dots for ratio calculation.
