Summary:To provide an estimation device capable of accurately estimating an interval between fixtures in the same fixture row.SOLUTION: An estimation device 10 includes: at least a position specification part 11 for specifying positions of a plurality of screws 6, 6,... for an image G including a rectangular gypsum board 5, from the image G; a screw number estimation part 14 for estimating the number of screws 6 in a long side direction of the gypsum board 5 based on a peak value of a synthetic waveform W obtained by generating a mountain-shaped waveform w at a position in a short side direction of the gypsum board 5 for each of the screws 6 based on the positions of the specified screws 6, and synthesizing the generated mountain-shaped waveform w in a long side direction of the gypsum board 5; a screw row determination part 15 for determining that the estimated screw is a screw of a screw row driven into the gypsum board 5 in the long side direction, when the number of estimated screws 6, 6,... is equal to or larger than a specified number; and a pitch calculation part 17 for calculating a screw pitch of the adjacent screws 6, 6 for the determined screw row.SELECTED DRAWING: Figure 2 【課題】同じ固定具列の固定具同士の固定具の間隔を正確に推定することができる推定装置を提供する。【解決手段】推定装置１０は、矩形状の石膏ボード５を含む画像Ｇから、画像Ｇに対する複数のビス６、６、...の位置を特定する位置特定部１１と、特定したビス６の位置に基づいて、ビス６ごとに、石膏ボード５の短辺方向の位置において山状波形ｗを生成し、生成した山状波形ｗを石膏ボード５の長辺方向に沿って合成することにより得られた合成波形Ｗのピーク値に基づいて、石膏ボード５の長辺方向に沿ったビス６の個数を推定するビス個数推定部１４と、推定したビス６、６、...の個数が規定個数以上である場合に、推定したビスを、長辺方向に沿って石膏ボード５に打ち込まれたビス列のビスであると判定するビス列判定部１５と、判定したビス列に対して、隣り合うビス６、６のビスピッチを算出するピッチ算出部１７と、を少なくとも備える。【選択図】図２
