Accelerometer-based correction of skewed horizon and keystone distortion in digital photography
作者：
Highlights：
• On-board accelerometers make feasible perspective correction in digital photography.
• Perspective correction is obtained with no human intervention.
• Perspective correction can be applied also to zoom lenses.
• Accelerometer calibration is necessary to get high accuracy.
• Accelerometer pose has to be estimated carefully to get high accuracy.
