Abstract
An overhead-view image of a work site is presented to an operator of a work machine even when the number of imaging devices at a construction site is lacking. The present disclosure provides an information presentation device for generating and outputting a terrain image relating to a construction site. The information presentation device includes a storage device that stores a program for performing a predetermined imaging process on the terrain image, and a processor for reading the program from the storage device and generating the terrain image. The processor performs: a process of using an image of the construction site acquired by at least one imaging device installed at a construction site, to acquire a first overhead-view image representing a current terrain of the construction site as viewed from above; a process of acquiring a second overhead-view image acquired by a method other than capturing by the imaging device installed at the construction site, and representing an original terrain of the construction site as viewed from above; and an image synthesis process of superimposing the first overhead-view image and the second overhead-view image to generate a first synthesized overhead-view image.
