| Abstract(in English) | In this report, we propose and describe a new recognition procedure for a low quality character string printed on a steel piece for Factory Automation. The character string consists of alphanumerals and '-'. The procedure includes the image emphasis with Gaussian Laplacian filter, the extraction of the character string image, the segmentation-recognition with the dynamic programming, and the high accuracy character recognition. We evaluated the accuracy for 1036 images (=8806 characters) scanned by the monochrome video camera at an actual steel producting factory line. The average recognition rate was 99.2% for the character recognition, and 91.6% for the character string recognition. |
