Method of improving alignment and positioning of an image capture device utilizing feature extraction transformation techniques

A method of assisting a user in alignment and positioning of an image capture device incorporating an image sensor, said method comprising:

• obtaining a preview digital image from the image capture device in real time;
• performing a Hough transform on said digital image in real time and generating a plurality of accumulator peaks therefrom;
• generating adjustment feedback in accordance with said plurality of accumulator peaks;
• and
• providing said feedback to a user of said capture device for adjusting alignment and positioning of the image capture device so as to minimize distortion in the preview digital image.

A computer implemented method of aligning, positioning and capturing a digital image using an image capture device, said method comprising:

• obtaining a preview digital image in real time from an image sensor incorporated in the image capture device;
• performing a Hough transform on said digital image in real time and generating a plurality of accumulator peaks therefrom;
• generating adjustment feedback in accordance with locations of said plurality of accumulator peaks;
• providing said feedback to a user of said capture device for adjusting alignment and positioning of the image capture device so as to minimize distortion in the preview digital image;
• and
• repeating said steps of obtaining, performing, generating and providing until the alignment of said image capture device is within a predetermined tolerance at which time a digital image is captured by said image capture device.
