Title: Automatic reader for fuel number
Inventor: KUBO KATSUMI
IPC: G06K9/62
Filed: 1987-09-22
Abstract: PURPOSE:To automate fuel control in atomic power facility or the like by allowing an operation processor to recognize characters typed out on a tie plate part by means of a ten-plate matching method using a ten-plate for alphabets, numerals, etc., stored in an image memory. CONSTITUTION:A mask 17 corresponding to three picture elements are moved in X and Y directions, distances (picture elements) in Z and U directions are sequentially added, stored in an image memory 6 and binarized by using the number of picture elements proportional to the length of the tie plate part as a threshold and area division (labeled) is executed to extract the tie plate part. Then, an inclination is found out from a binary image, the coordinates xcn, ycn of the center image of the binary image are found out, the original image is converted at its coordinates, and an erected image is obtained. The character identification of the processed image is executed by ten plate matching method. In the ten plate matching method, a character is determined as an objective one when the maximum value of similarity is a fixed value or more and the similarity difference of the succeeding candidate is a fixed value or more. Consequently, an identification number can be automatically read out.
