Methods and systems for determining a characteristic of a surface

A system for determining a characteristic of a surface, comprising:

• an imaging device configured to capture an image of the surface,
• wherein the imaging device is calibrated to the surface,
• wherein the imaging device comprises a lens and a lens distortion parameter;
• a positioning device configured to:
• for each tie point,
• capture a plurality of location coordinates of a point marker located on the surface using a positioning device that is calibrated to the imaging device, and
• capture an additional plurality of location coordinates of an additional point marker;
• and
• a feature analysis system configured to:
• display the image,
• identify a plurality of tie points on the image,
• for each tie point,
• calculate a plurality of transformation parameters,
• identify an additional point marker located on the surface,
• plot a plot point on the image automatically transformed from the additional point marker, and
• calculate a feature of the surface based on the plurality of tie points and the plot point.
