Summary:PROBLEM TO BE SOLVED: To provide a method for generating teacher data for image recognition, while reducing the number of images as the basis.SOLUTION: A taken image is acquired in a manner that an image of an object is taken by an imaging device C located at a first specified position P, and a basis image region Sis extracted from the acquired image. The result produced by converting the coordinates of the basis image region Sfrom an image coordinate system to the coordinate system of an image taken by the imaging device C if it is assumed that the imaging device C is located at a second specified position P, not the first specified position P, is generated as the teacher data.SELECTED DRAWING: Figure 1 【課題】基礎となる画像の数の低減を図りながら、画像認識用の教師データを生成する方法を提供する。【解決手段】第１指定位置Ｐiに配置された撮像装置Ｃにより対象物を撮像することによって撮像画像が取得され、そこから基礎画像領域Ｓiが抽出される。基礎画像領域Ｓiが、一の画像座標系から、第１指定位置Ｐiとは異なる第２指定位置Ｐjに配置されたと仮定された場合の撮像装置Ｃによる撮像画像の座標系に対して座標変換した結果が、教師データとして生成される。【選択図】 図１
