Frontal Image

Select 4 corners of a rectangle object in an image. Then this app will simulate what it looks like if you are standing directly in front of it.
The calculation requires the focal length and optical center of the camera from which the image is taken. The app is installed with default values for those parameters and you can modify them in the app.

Important: This app requires OpenCV Manager to be installed. OpenCV is a programming library which provide some functions this app relies on. The app will prompt you for installation when it cannot find the library.
