CameraCal description

THIS APPLICATION DOES NOTHING WITH THE CAMERA ITSELF OR WITH YOUR ANDROID CAMERA APPLICATION. THE TARGET GROUPS ARE RESEARCHERS AND STUDENTS.

Simple application to calculate the intrinsic and extrinsic parameters with pinhole camera model. These parameters can be used by OpenCV or other frameworks to compensate for lens distortions for scientific purposes.

How to use:
1. Search for a chessboard pattern with Google and print it out.
2. Place the chessboard pattern on a table or a paper clipboard.
3. Run CameraCal, select the desired camera and resolution.
4. Determinate the right landscape or reverse landscape position for the device to see the right orientation in the image preview.
5. Watch the chessboard pattern inside the preview to see if the pattern can be detected.
6. Add 5-50 images with "Add image" button when the pattern is in different places inside the field of view.
7. Click on "Finish" to calculate the parameters:
Fx, Fy -> focal point
Cx, Cy -> center point
5 distortion coefficients.
