摘要： PURPOSE:To correctly recognize a KANJI (Chinese character) in a short time by alternately disposing black points and white points on the upper side and the left side of an information element, disposing the white points on a lower side and a right side and reading a code on which a point representing information is disposed by an image scanner. CONSTITUTION:In order to obtain the entry position of the information element, the positions Xa, Ya,...Xd, Yd of the points (a), (b), (c), (d) of the four corners of an external frame are obtained to obtain the coordinates of the points 11, 12, 21, 22 of the reference of four bits. The widths of the external frame are respectively subtracted from the distance of the X axis direction of the point (a) and the point (c), and the point (b) and the point (d) and averaged to have the length of the X axis direction occupied by a piece of information and they are two columns, so that they are divided equally into two to obtain the width Xs of the piece of information. On a Y axis, Ys is similarly obtained. The width of the information obtained in such a way is added to the coordinate Xa, Ya of an origin, thereby, the coordinate of the reference of the information is obtained. However, when the number of the bits of a the information element is increased, the position detecting error of the information element is increased. Then, as one part of the external frame, the black points and the white points are alternately disposed to measure the position of the black points, thereby, more correctly obtaining the position of the information.

摘要： PURPOSE:To recognize a KANJI (Chinese character) code at high speed by a short program by encoding a KANJI and directly recognizing. CONSTITUTION:The points of the four corners of the code are respectively defined to be (c), (d), (e), (f). The 1, 2, 23, 24 rows and 1, 2, 23, 24 columns of a picture element are frames and black. 3-7 rows indicate the information of 4 bits (0100) for representing a numeric character 2. Since the 3-7 rows have the least significant bit of 0, they are white, since 8-12 columns show the numeric character of 1, they are black, and since 13-17 columns and 18-22 columns show 0, they are white. Since 8-12 columns show the numeric character of 0, 13-17 columns show 3 and 18-22 columns show 3, the JIS code 2033 of the character of KAN (Chinese) is represented. Then, the code is inputted to a computer by an image scanner to detect the coordinates of the four corners of the frame, calculate the position of respective information bits from the values, decide 1 or 0 according to that there are many white points or black points at a relevant position and read the numeric character represent one KANJI.

摘要： PURPOSE:To easily confirm the welding joint position of piping by feeding the sensor of a ferrite scope in the axial direction and the peripheral direction of the piping, in a shape that is pressed against the wall surface of the piping. CONSTITUTION:A welding joint 2 exists in plural inlet/output pipes 1 circulating primary refrigerant to the fuel rod (not shown in the figure) of a nuclear reactor, and an ultrasonic flaw detecting test is performed periodically to the joint 2. The probe of an ultrasonic flaw detector is attached to a gear box 4 together with the sensor 29 of a ferrite scope, brought to a reciprocating motion in a prescribed section in the axial direction of the pipe 1, and also, fed in the peripheral direction. In such case, the attenuation of magnetic induction caused by the variation of the quantity of ferrite is detected by the ferrite sensor 29. Subsequently, from such detection quantity, the welded zone of the welding joint 2 is confirmed, and by the output of the ultrasonic probe 28, the non- destructive inspection of the welded zone is performed. In such way, the welded zone can be exactly, confirmed therefore, the reliability of the flaw detection is improved.

摘要： PURPOSE:To recognize character graphic with high accuracy regardless of the size variation of the character patterns or the mixture of graphic of different sizes, by performing the matching among character patterns after recognizing the positioning to a dictionary and the ratio of sizes between the dictionary and the input character graphic. CONSTITUTION:A processor recognizes the address of a picture memory where the center of a dictionary is coincident with the center of an input character graphic and then operates the address of a point A' of a picture memory corresponding to a point A of the dictionary as well as a correction address used for shift to the next point B' according to the size ratio between both centers. Then the processor sets these addresses to a matching circuit. The matching circuit operates and counts the coincidence frequencies between data of the dictionary and the input character pattern automatically the matching address of a picture memory corresponding to the dictionary after the horizontal, and vertical matching start address and correction address are set and a start command is given from the processor. In such a way, the matching circuit produces a matching address of an input picture to the position of a dictionary.

摘要： PURPOSE: To surely judge whether a dot character symbol printed on a food can or the like is good or not. CONSTITUTION: The check pattern of each character is generated from the image of a check object character string by picture processing (102 to 105). Each input character is collated with a pattern 2 of the normal character and a pattern of a dot omitted character which can be correctly read regardless of drop-out of dots and if it doesn't coincide with the pattern 2 neither the pattern 3, it is judged to be a defective print (106 to 111). Since the input character coincides with the pattern 3 and is judged to be good when it is correctly read regardless of drop-out of dots, effects of improvement of the yield of products, improvement of the line operating ratio, etc., are obtained.

摘要： PURPOSE:To calculate an evaluating function S at high speed, and to recognize a picture pattern by adding a value P (i, j) of a standard pattern when each picture element value T (i, j) of an objective pattern is one, and adding the value obtained by inserting the P (i, j) when the value is zero. CONSTITUTION:When the value of the picture element of the standard pattern P (i, j), which is normalized to (n) picture elements in a length and to (m) picture elements in a breadth, is set at K bits, and the picture element value of P (i, j) is set at >= three, for the value of a difference function D (i, j), if the judging objective pattern, which is stored into an eight-bit register 111, T (i, j) = 1 is obtained, and the value of the register 111 is added to a 16-bit adder 115 by a selector 114, D3 (i, j) = P (i, j) is set, at the time of T (i, j) = 0, the value of an inverter 112 is added to the adder 115, and D3 (i, j) = 2K-1-P (i, j) is set. Further the initial value of the standard pattern P (i, j) is changed from 2 to 2 -1, it is set so as to be different from the picture element values in the all directions, when a learning pattern L (i, j) is one, P (i, j) is increased by one, when L (i, j) is zero, one P (i, j) is decreased by one, and the learning is executed. Thus the calculating time of the evaluating function S of a binary picture in an evaluating function computer 11 can be drastically shortened.
