HeliPitch for Iphone Publisher's description
from Stefan Grufman
HeliPitch is an application for controlling the rotor blade pitch angles on your remote controlled helicopters
HeliPitch is an application for controlling the rotor blade pitch angles on your remote controlled helicopters. It uses the preview video stream of the videocamera in your iPhone. The application uses image processing to identify your rotor blades and once identified, it will approximate these with lines that gives the angle. All is done in realtime and typically it will process the images in 4-5 fps on an iPhone 4.
To work, you should fold the blades backwards (aligned with the boom). By doing this, the actual pitch angle can be measured as taking the angle between the blades and divide this with two.
To get the application to work it is best to follow a few rules:
- Avoid to have many 'lines' behind the helicopter that can be mistaken as rotor blades, i.e. same length, angle etc.
- Make sure that the blades fill the aiming box, but are not larger than this box.
- Make sure that the rotorhead is held within the aiming circle.
- Try and hold the camera as still as possible and avoid motion blur.
- Take a few measures and check that is seems ok.
I cannot guarantee the quality of the measurement. If you are unsure, you should not fly without checking the pitch angles in another way. I cannot be held responsible for personal injury or damage to your iPhone or helicopter.
Light - Will enable/disable the camera flash for extra light.
Reset - Will clear the last read angle and lines.
Swap - Swap between Left/Right aiming.
Please note that continued use of the flash may dramatically decrease battery life.
This application will be FREE during the first launch time. Without further notice it will however be a paid application.
