1. An image processing device comprising:
an input circuit configured to accept inputting of a point or line to a captured image captured by a camera; and
a display configured to display a first image indicating the point or line upon mapping on a plane parallel to a ground surface, on the basis of predetermined camera parameters indicating a position and attitude of the camera, a position on the captured image of the point or line, and height information on a real space of the point or line,
wherein
the input circuit accepts inputting a line tracing a shape of an object having a known shape appears on a ground surface of the captured image,
the display displays, in accordance with the predetermined camera parameters indicating the position and attitude of the camera, a position of the line on the captured image and height information of the line in the real space, wherein the first image indicates the line mapped on a plane parallel to the ground surface, the first image is used to confirm whether the predetermined camera parameters are appropriate, and the first image appears differently depending on whether camera parameters at a time of capturing the captured image are the same as the predetermined camera parameters, and
the first image further indicates at least one of a position of the camera and a field of view of the camera.
