Claim One:
1. A method for capturing a valid snapshot of an image, the method comprising: identifying a set of calibration parameters based at least in part on the image, a first snapshot, a two-dimensional surface on which the image is located, and a reference bitmap corresponding to the first snapshot; identifying a first location of the first snapshot on the two-dimensional surface based at least in part on one calibration parameter within the set of calibration parameters; capturing the first snapshot at the first location on the two-dimensional surface; defining a first alignment relationship between the reference bitmap and the first snapshot; determining whether the first alignment relationship is valid based on a first alignment value of the first alignment relationship being applied to an alignment threshold value; and responsive to the first alignment relationship not being valid, validating a second alignment relationship of a second snapshot of the image and the reference bitmap by performing the steps of: capturing the second snapshot at a second location on the two-dimensional surface, the second location being within an adjustment distance threshold of the first location; defining the second alignment relationship between the reference bitmap and the second snapshot; validating the second alignment relationship in response to a second alignment value of the second alignment relationship being less than the alignment threshold value; and designating the second snapshot as the valid snapshot.
