Zusammenfassung:To provide an information processing apparatus configured to measure a height of a plant body more accurately, an information processing method, and a program.SOLUTION: An information processing apparatus 100 includes: a digital surface model acquisition unit 150 which acquires a digital surface model (DSM) representing a distribution of altitude values of spots in an image, the model being generated from three-dimensional data based on the image including plant bodies captured from the above; an analysis section setting unit 170 which sets an analysis section, using a measurement target region in the image as a reference; a digital terrain model calculation unit 180 which generates a digital terrain model DTM representing a distribution of altitude values excluding the plant bodies in a region including the measurement target region, on the basis of the altitude values in the analysis section included in the digital surface model; and a crop surface model generation unit 190 which generates a crop surface model (CSM) representing a distribution of altitude values in the measurement target regions, as a distribution of a height of the plant bodies, on the basis of the digital surface model and the digital terrain model.SELECTED DRAWING: Figure 1 【課題】より正確に植物体の高さを計測することができる情報処理装置、情報処理方法、およびプログラムを提供する。【解決手段】情報処理装置100は、上方から撮影された植物体を含む画像に基づく三次元データから生成された、画像内の各地点の標高値の分布を表すデジタル地表モデル(DSM)を取得するデジタル地表モデル取得部150と、画像における計測対象領域を基準として解析区を設定する解析区設定部170と、デジタル地表モデルに含まれる解析区内の標高値に基づいて、計測対象領域を含む領域内の植物体を除く標高値の分布を表すデジタル地形モデルDTMを生成するデジタル地形モデル演算部180と、デジタル地表モデルとデジタル地形モデルとに基づいて、計測対象領域内の標高値の分布を植物体の高さの分布として表す作物表面モデル(CSM)を生成する作物表面モデル生成部190と、を備える。【選択図】図1
