Program for creating work assistance data

Provided is a technology that facilitates the following: associating a work procedure with a 3D model based on the state of an actual work area; adding and registering a work viewpoint image to the 3D model; and registering a work item in an existing work procedure to the 3D model. A program for creating data causes a computer to execute the following: a step in which a converted image, which is a whole-view image the viewpoint of which was switched, is created on the basis of a 3D model generated from a plurality of whole-view images which include a plurality of work targets; a step in which the position of a work viewpoint image, which is captured from the line of sight at which work is carried out, is determined on the basis of the degree of similarity obtained by comparing the converted image and the work viewpoint image, and in which information related to a work target on which work is carried out is registered on the whole-view image; and a step in which the work viewpoint image that corresponds to a r
