COUNTING APPARATUS AND COUNTING METHOD

To provide a counting apparatus and a counting method which can reduce influence of disturbance elements such as illumination, light source, luminance, and a surface shape of a measured object and can count the number of objects with high accuracy.SOLUTION: A counting apparatus according to the present invention has a three-dimension detection apparatus 5 for detecting three-dimensionality of a plurality of count objects, an arithmetic unit for generating crosse-section 2D signal data, which is 2D data on a given cross section, from the 3D data acquired by the three-dimension detection apparatus 5 and for detecting an object 2D signal indicating a cross section shape of the count object from the cross-section 2D signal data to calculate to a position of the detected object 2D signal, and a display control unit for counting the number of the plurality of count objects from the position of the detected object 2D signal.SELECTED DRAWING: Figure 1 【課題】照明や光源、照度、被測定物の表面性状といった外乱要素の影響を低減でき、高い精度で対象物の員数を計数することができる、計数装置及び計数方法を提供する。【解決手段】複数の計数対象物の立体を検出する立体検出装置５と、立体検出装置５で取得した３Ｄデータから任意の断面の２Ｄデータである断面２Ｄ信号データを作成し、断面２Ｄ信号データから計数対象物の断面形状を示す対象物２Ｄ信号を検出し、検出した対象物２Ｄ信号の位置を演算する演算部と、対象物２Ｄ信号の位置から、複数の計数対象物の員数を計数する表示制御部と、を備える、計数装置。【選択図】図１
