The invention discloses a teacher data generation method. Provided is a method for generating teacher data for image recognition while reducing the number of images used as the basis. A captured image is obtained by imaging an object by an imaging device C arranged at a first designated position Pi. A basic image region Si is extracted from the captured image. The teacher data is generated as a result of coordinate transformation of the basic image region Si from one image coordinate system to a coordinate system of a captured image by the imaging device C on the assumption that the imaging device C is arranged at a second designated position Pj which is different from the first designated position Pi. 本发明提供种示教数据生成方法。通过被配置在第1指定位置P上的拍摄装置(C)拍摄对象物，获取拍摄图像，并从获取的拍摄图像中抽取基础图像区域S。生成下述结果作为示教数据，该结果是指：基础图像区域S从个图像坐标系相对下述假设的拍摄图像的坐标系进行了坐标变换的结果，该假设的拍摄图像是假设拍摄装置(C)被配置在与第1指定位置P不同的第2指定位置P上时由该拍摄装置(C)拍摄的拍摄图像。根据本发明的方法，能够在实现降低作为基础的图像的数量的同时，生成用于图像识别用的示教数据。
