摘要： Techniques and tools are described for performing perspective correction using a reflection. Reflective properties of a surface being photographed can be used to determine a rotation of the device taking the photograph relative to the surface. Light sourced or produced by the device can be used to create a reflection spot in the picture. A position of the reflection spot within the picture is calculated and used to determine the rotation. The rotation can be used for performing perspective correction on the picture, or on another picture taken by the device.
