Information processing apparatus implementing a piping and instrumentation diagram, information processing method, and program

The information processing apparatus comprising a processor configured to:

• retrieve a drawing from a storage;
• display the drawing on a display in which a plurality of elements are indicated by graphics and in which a connection relationship between the plurality of elements is indicated by connecting lines, that contains a plurality of the graphics;
• receive via an input interface a drawing of a trajectory from a user, in the drawing displayed on the display;
• automatically extract from the drawing, as one or more first elements, elements of the plurality of elements, indicated by the graphics, that are completely contained within a region whose outer periphery is defined by the trajectory drawn by the user;
• automatically extract from the drawing, as one or more second elements, elements of the plurality of elements, indicated by the graphics, that intersect a boundary of the region for which the selection is received;
• for each of the one or more automatically extracted second elements, automatically determine whether a positional relationship between a center of graphic indicating a second element among the one or more second elements and the boundary of the region is a specific relationship, and automatically extract said second element among the one or more second elements as a third element when the positional relationship between the center of graphic indicating said second element among the one or more second elements and the boundary of the region is the specific relationship;
• automatically store a set of elements including the one or more first elements and the third element in the storage as an element group selected by the user;
• and
• automatically search for, from the drawing, an element group that conforms to the element group selected by the user;
• automatically display the searched element group on the display in correspondence with a position on the drawing;
• and
• correct the element group that conforms to the element group selected by the user.

An information processing method to be performed by a processor of an information processing apparatus, the information processing method comprising:

• retrieve a drawing from a storage;
• display the drawing on a display in which a plurality of elements are indicated by graphics and in which a connection relationship between the plurality of elements is indicated by connecting lines, that contains a plurality of the graphics;
• receiving via an input interface a drawing of a trajectory from a user, in the drawing displayed on the display;
• automatically extracting from the drawing, as one or more first elements, elements of the plurality of elements, indicated by the graphics, that are completely contained within a region whose outer periphery is defined by the trajectory drawn by the user;
• automatically extracting from the drawing, as one or more second elements, elements of the plurality of elements, indicated by graphics that intersect a boundary of the region for which the selection is received;
• for each of the one or more automatically extracted second elements, automatically determining whether the graphic indicating a second element among the one or more second elements is connected by the same connecting line as a first element among the one or more first elements, and automatically extracting said second element as a third element when the graphic indicating said second element is connected by the same connecting line as the first element among the one or more first elements;
• and
• automatically storing a set of elements including the one or more first elements and the third element in the storage as an element group selected by the user;
• automatically searching for, from the drawing, an element group that conforms to the element group selected by the user;
• automatically displaying the searched element group on the display in correspondence with a position on the drawing;
• and
• correcting the element group that conforms to the element group selected by the user.

A non-transitory computer readable storage medium storing a computer program which, when executed by a computer, causes the computer to at least:

• retrieve a drawing from a storage;
• display the drawing on a display in which a plurality of elements are indicated by graphics and in which a connection relationship between the plurality of elements is indicated by connecting lines, that contains a plurality of the graphics;
• receive via an input interface a drawing of a trajectory from a user, in the drawing displayed on the display;
• automatically extract from the drawing, as one or more first elements, elements of the plurality of elements, indicated by the graphics, that are completely contained within a region whose outer periphery is defined by the trajectory drawn by the user;
• automatically extract from the drawing, as second elements, elements of the plurality of elements, indicated by the graphics, that intersect a boundary of the region for which the selection is received;
• for each of the one or more automatically extracted second elements, automatically determine whether the graphic indicating said second element among the one or more second elements is connected by the same connecting line as a first element among the one or more first elements, and automatically extract said second element as a third element when the graphic indicating said second element is connected by the same connecting line as any first element among the one or more first elements;
• and
• automatically store a set of elements including the one or more first elements and the third element in the storage as an element group selected by the user;
• automatically search for, from the drawing, an element group that conforms to the element group selected by the user;
• automatically display the searched element group on the display in correspondence with a position on the drawing;
• and
• correct the element group that conforms to the element group selected by the user.
