An information display system includes circuitry to acquire detection information including information on a posture of a user and information on a line of sight of the user, project an image onto a projection destination located in a projection direction with respect to the user, and cause the image to be projected onto the projection destination based on the detection information and information on the projection direction.

Information display system, information display method, and non-transitory recording medium

A coefficient to transform a three-dimensional mesh approximating at least a part of a three-dimensional model including at least a part of a target object and generated from a plurality of two-dimensional images, into two-dimensional panoramic coordinates is determined. A first position on a first image determined from a plurality of two-dimensional images corresponding to a portion of the two-dimensional panoramic coordinates, and an annotation to be projected onto the two-dimensional panoramic coordinates are specified according to the first image. A second position corresponding to projection of the annotation onto the two-dimensional panoramic coordinates is determined. The annotation is superimposed on a second image obtained by projecting the first image onto the two-dimensional panoramic coordinates. A third position corresponding to projection of the first position onto a third image is determined, and the annotation is projected and superimposed at the third position on the third image.
