摘要： PROBLEM TO BE SOLVED: To specify a victim at a disaster, etc., and to specify the accurate location of the dis as ten by using a portable telephone system and a portable telephone terminal. SOLUTION: A plurality of radio base stations 1 that respectively construct an area transmit particular emergency radio wave signals to the portable telephone terminal 3 according to an instruction from a radio exchange 2 by using the portable telephone system having the plurality of radio base stations 1. The portable telephone terminal 3 that has received the emergency radio wave signal converts self-ID information (name, telephone number, etc.), stored in the terminal into a sound signal (Morse signal and DTMF(dial tone multi frequency) signal) and outputs the sound signal as emergency transmission sound with sound volume larger than that of normal calling sound. A person decodes the Morse signal from the emergency transmission sound and decodes the DTMF signal into ID information with an ID detection device to specify the owner and the location of the telephone terminal.

摘要： PROBLEM TO BE SOLVED: To provide a template matching method which can fast retrieve its object despite variance of the object and has its high representing/retrieving efficiency and also high reliability of its retrieval result by parametrically representing a standard template space if the retrieval object has its variance. SOLUTION: A standard template space is parametrically represented if a retrieval object has its variation. In this template matching method, a parametric template space is formed from a standard template set and the template is orthogonally decomposed via the template space in a 1st procedure. In a 2nd procedure, the templates which are orthogonally decomposed are selected in descending order of the proper value and an approximate parametric template space of a smaller number of parameters is formed. In a 3rd procedure, the template matching is performed in the approximate parametric template space. Thus, the original template space is compressed and the matching efficiency is improved.

摘要： PROBLEM TO BE SOLVED: To reliably give a fast and precise position/angle estimating result in a template matching method using a coarse-to-fine method, etc. SOLUTION: Grids at the sampling intervals of Δx in an (x)-direction, Δy in a (y)-direction and Δθ in a rotating direction are considered and a reference template obtained by parallelly advancing and rotting by a quantity corresponding to each grid point and a searching picture there are matched with each other to generate a candidate for detail search. Next a parametric template space is constituted from its adjacent neighborhood at the position of each generated candidate to estimate an optimum position/angle. Next, the parametric template space is repeatedly reduced by zooming in the (x)-direction, the (y)- direction and the rotating direction with an estimated position/angle in a center to be the positional precision of a sub-pixel at last. Then a position/angle giving a maximum normalized and correlated value among the respective candidates estimated by the sub pixel is made the estimated position/angle.

摘要： PROBLEM TO BE SOLVED: To provide a check method which stably discriminates between good articles and defective articles in accordance with a reference image and a check image picked up in the same photographing condition even with respect to characters or patterns existing on the surface of a check object like industrial parts. SOLUTION: A sample to be a reference of good articles is selected to acquire a reference image (101), and the check image of a check sample is acquired in the same manner (102), and a density difference picture between the reference image and the check image is obtained (103). Meanwhile, area division is performed by edge extraction of the reference image (104). A variation of residual variance of the residual to each threshold is calculated for each obtained area, and a maximum value of these variations is obtained (105). Based on the obtained maximum variation, it is discriminated whether the check sample is good or not (106).

摘要： PURPOSE:To detect the bend-point position of a contour for an object with good accuracy by a method wherein a contour stroke whose flat section is long is approximated by a straight line or a curve on the basis of the method of least squares and a contour stroke whose flat section is short is approximated after it has been projected in the direction of a plate obtained by a long-contour-stroke part. CONSTITUTION:A contour-shape measuring part 1 measures the cross-sectional contour shape of an object, and it stores a contour stroke in a contour-stroke storage part 2. A temporary-bend-part detection part 3 performs a comparison with a threshold angle and a maximum and minimum point detection, and it stores them in a temporary-bend-point storage part 4. A cross-sectional-shape judgment part 5 investigates whether the condition of a thin-sheet stack has been satisfied or not with reference to a temporary bend point stored in the storage part 4. When the condition is satisfied, the contour stroke stored in the storage part 2 is stored in a temporary-upper-sheet-section-stroke storage part 6, a temporary-edge-section-stroke storage part 7 and a temporary-lower-sheet-section-stroke storage part 8. Regarding the individual strokes which have been stored, the individual strokes are approximated on the basis of the method of least squares, and they are stored in an approximate-line- group storage part 12.

摘要： PURPOSE:To apply coding a lump of graphic form as one or plural polygon data within a prescribed number of strokes by providing a poly-line generating means for replacing a part of the boundary of the graphic form from connected black line end point information into a poly-line. CONSTITUTION:A graphic input device 55 receives an instruction of a control section 56 and reads one line's content from the graphic form written with a graphic form and stores the result temporarily in a buffer 57. A black line detecting section 58 detects a black line from the data in the buffer 57 and the information is written and stored in one register of a line register 59, e.g., into an address corresponding to both ends of the black line for specific value. A poly-line control section 60 checks the connecting state of the black line from the information stored in the register 59 to apply discrimination such as generation, connection or extension of the partial boundary and the result is fed to a poly-line generating section 61. The generating section 61 applies processing such as registration of a new boundary to a poly-line data table 62 or extension of the stored partial boundary and generates a polygon data finally.

摘要： PURPOSE:To allow extraction of graphic factor connecting lines connecting with grapic factors and recognition of connecting relation of mutural graphic factors by finding the precise direction of graphic line. CONSTITUTION:A figure is inputted from an input device 41 and graphic data are stored in a frame memory 42. A control part 43 reads out data such as a size of a position coordinate of a graphic factor extracted from a graphic element extracting part 44 and its type, and transmits them into an investigation circular coordinate generating part 45, which generates external/internal investigation circular coordinate string enclosing graphic factors in accordance with these data. An intersection detecting part 46 receives said data, and reads out their picture element data from the frame memory 42. After it detects an intersection of an investigation circle and a graphic line, it stores its coordinate value in a buffer 47. An intersection decision part 48 detects a pair of intersections which have possibility of a short straight line at both sides by a detecting pair from intersections stored in the buffer 47, and transmits coordinate value data of this pair of intersections to a straight line tracking part 49.
