7. A projection system comprising:
a projection device that includes a laser scanner and projects one or more drawings individually onto work spots in a work site;
an adjustment unit configured to adjust at least one of (i) a quantity of the one or more drawings to be simultaneously projected by the projection device or (ii) a setting parameter regarding a mode of projection performed by the projection device;
a judgment unit configured to judge whether a drawing among the one or more drawings is projectable onto the work spots; and
a storage configured to store information indicating a work spot judged by the judgment unit to be a work spot onto which the drawing is unprojectable,
wherein the projection device stops projection of the drawing onto the work spot judged by the judgment unit to be a work spot onto which the drawing is unprojectable, and
when a location of the projection device is changed, the projection device resumes projection of the drawing onto the work spot for which projection of the drawing is stopped, based on the information stored in the storage.
