Abstract
A storage device includes at least one processor. The at least one processor is configured to acquire a surface scan image in an image tile format of a set size, bind a set number of image tiles in one segment, and store a plurality of segments as files, respectively, instead of storing the image tiles without modification.
Claims9
A storage device comprising:
- at least one hardware processor,
- wherein the at least one hardware processor is configured to:
- acquire a surface scan image in a format of image tiles of a set size;
- bind a set number of image tiles in one segment;
- store a plurality of segments as files, respectively, instead of storing the image tiles without modification;
- arrange the plurality of image tiles in rows and columns according to the pieces of location information of the image tiles;
- bind the plurality of image tiles arranged in the rows and the columns by a row-directional set value and a column-directional set value to generate the segments;
- classify the pieces of location information of the specific image tiles into row locations and column locations;
- and
- generate the files such that the file names include first values obtained by dividing the row locations by the row-directional set value and second values obtained by dividing the column locations by the column-directional set value.
