PURPOSE:To simply recognize the visual feature of work at high speed by identifying a picture specified by the difference of the light and dark level of the stored picture after fetching and storing the form of the work as the picture and calculating the position of the specified picture. CONSTITUTION:A fetching means 1 fetches the form of work as a picture and the picture is stored by a storing means 2. Next, a picture identifying means 3 discriminates the difference of the light and dark level of the picture stored by the storing means 2 and extracts the picture formed by the difference of the light and dark level based on a discriminated result. Then, a comparing means 4 compares the picture extracted by the identifying means 3 and a basic picture set in advance. An arithmetic means 5 specifies the picture extracted only when the compared result satisfies fixed judging conditions and calculates the position of the specified picture. Thus, the feature of the form of the work can be recognized simply at high speed. |
