A tool to experimentally determine the field of view for Augmented Reality overlays by interactively matching reference shapes.
Build and run FOVfinder.xcodeproj on an iDevice. The app will run on the simulator, too,
but will give you no camera image.
On the main view use a pinch gesture to adjust the field of view so that the white overlay frames match the reference objects in the camera preview. The field of view may be determined for landscape and portrait orientation.
Use two-finger pan up and down to adjust the zoom factor, if available in the currently active video format.
A tap on the camera preview toggles the navigation and tool bars in the main view.
Use the Settings view to adjust video format and gravity as well as size and offsets of the overlay frames. All measures are given in centimeters, but the underlying projection geometry is basically unit-less.
- ARC
- iOS >= 7.0
- Xcode >= 5
- iDevice, since Simulator does not have a camera
