PROBLEM TO BE SOLVED: To provide a surface height display method with which it is possible to display a present state surface height relative to a planned finished surface in correspondence to a range in which surface finishing work is carried out, allowing a worker to finish the surface height closer to the planned finished surface on the basis of the display.SOLUTION: A relative position to the position of a planned finished surface is specified and a marker 1 of a prescribed shape is installed, then a surface A and the marker are photographed with the photograph device of a tablet type terminal device 2. The relative positions of the marker position and the photographing position are specified from the position and shape of the marker seen in the photographed image, and, from the relationship of the planned finished surface whose relative position to the marker is specified with the photographing position, present state surface height information is displayed, at the position of the planned finished surface in the image photographed from the photographing position, by superposition on the image photographed from the photographing position.SELECTED DRAWING: Figure 4 【課題】計画仕上げ面に対する現況の表面高さを、表面の仕上げ作業を行う範囲に対応して表示し、作業者が該表示に基づいて表面高さを計画仕上げ面に近い状態に仕上げることができる表面高さ表示方法を提供する。【解決手段】計画仕上げ面の位置と相対的な位置を特定して所定の形状のマーカー１を設置し、タブレット型端末機２の撮影装置で表面Ａ及びマーカーを撮影する。撮影した画像に写し込まれたマーカーの位置及び形状からマーカーの位置と撮影位置との相対的な位置を特定し、マーカーとの相対的な位置が特定されている計画仕上げ面と撮影位置との関係から該撮影位置で撮影した画像内における該計画仕上げ面の位置に、該撮影位置で撮影された画像に重ねて現況表面高さの情報を表示する。【選択図】図４
