ABSTRACT:
In a phase unwrapping method for fringe image analysis, when storing newly calculated numeric data into a storage list, the new numeric data is initially compared with numeric data of a representative rank within each rank block in the storage list, whereby the rank block to store the data is chosen. Subsequently, the new numeric data is compared with each of respective numeric data within thus chosen rank block, so as to determine a rank at which the new numeric data is to be stored, and then is stored into the storage list. Along with the storing of numeric data, rank data is updated.
