摘要： PROBLEM TO BE SOLVED: To design an outdoor facility in detail by recording detailed information of site continuously and automatically and transmitting information to a station and receiving instruction from the station, concerning the decision of the position of the outdoor facility in the stage of an on-the-spot investigation. SOLUTION: The present position of a moving vehicle is detected by using a GPS satellite (steps S1 and S2), and the name and number of outdoor facility are obtained from the result retrieved from database of design information based on the positional information (Steps S3 to S5). A vehicle is inclined every specified angle so as to photograph the periphery of site with a camera mounted to the vehicle (Step S6). Detailed information on site and detailed information on obstacles in its periphery are continuously recorded together, and the information corresponding optical items is updated and registered for addition (Steps S7 and S8). Then, after receiving an instruction from a station, various measurements such as soil exploration, detection of tilt angle of road surface in the periphery of the site, etc., are performed (Step S9), and the database of facility design information within the station or mounted on the vehicle is updated and registered for addition (Step S10).

摘要： PROBLEM TO BE SOLVED: To obtain information related to a required facility simply in a short time by accessing with the use of a terminal device from has one's new address. SOLUTION: A GPS receiver device 3 specifies positional information of a vehicle 1 with using navigation waves from an artificial satellite 8, and sends the information to a portable terminal device 4. In consequence, the terminal device 4 transmits the positional information to an information station 2 via, e.g. a modem, a telephone line or the like. When the information station 2 receives the positional information, a main computer 5 searches from a database which is a memory device 6 facility information, etc., corresponding to the positional information and transmits the information, etc., to the vehicle 1 via the modem, telephone line or the like. Accordingly, the facility information corresponding to the present position can be obtained quickly at the side of the vehicle 1.

摘要： PURPOSE:To automatically determine corresponding points between stereo images by recognizing an object to be searched by physical characteristics within a limited range of the object, obtaining a real space size from results where correspondence between right and left images has been obtained and examining a satisfaction degree of the physical characteristics to select correct corresponding points. CONSTITUTION:A searching region of an object to be searched is limited on each of right and left stereo images, and then the recognition of the object is performed with physical characteristics utilized. Further in correspondence between the right and left stereo images, stereo image pickup conditions are used to limit possible combination, and finally a size on a real space is calculated for the combination so that whether or not the physical characteristics may be satisfied is examined. Thus by taking four sequential steps of limiting, recognizing, making correspondence and examining, the correspondence of the object on the right and left stereo images and its three-dimensional distance can be automatically and efficiently obtained.

摘要： PURPOSE:To facilitate the accurate colorimetry of the cylindrical surface by composing the device of a mechanism which moves the center axis of the cylindrical surface in parallel, a color sensor, a light source, and a device which transforms coordinate values in a color space measured on the cylinder surface into coordinate values in a plane. CONSTITUTION:The cylindrical surface 5 as an object of colorimetry has its center axis 6 moved horizontally in parallel by a stage 4. The color sensor 7 is arranged having its view axis perpendicularly to a reference horizontal plane drawn by the movement track of the center axis 6. The light source 8 is fitted so that its optical axis is in a plane which crosses the center axis 6 at right angles and is perpendicular to the reference horizontal plane while crossing the view axis of the sensor 7 on the cylindrical surface 5. Reflected light L2' is converted photoelectrically by the sensor 7, amplified 9, and A/D-converted 10 to input a numeral which is proportional to the quantity of reflected light L2' to a computer 11. The computer 11 transforms the coordinate values in the color space measured by the cylindrical surface 5 into the coordinate values in the color space on the plane by using the relational expression among reflection characteristics of the cylindrical surface 5, the relative position between the cylindrical surface 5 and sensor 7, the ratio of a visual field and the diameter of the cylindrical surface 5, and the quantity of reflected light L2' to the sensor 7.

摘要： PURPOSE:To improve the measuring accuracy by obtaining previously a system error and the sub-pixel position of an edge when the edge direction is obtained from a digital picture and then correction the system error for the data obtained from an actual picture. CONSTITUTION:A correction table for system errors is obtained by an experiment for each sub-pixel position of an edge as a preparatory process in regard of a TV camera and a differential operator which are actually used. Then the edge direction and the edge sub-pixel position are measured for an actually photographed picture with use of the same TV camera and differential operator used in the preparatory process. The correction value of the edge direction is obtained by the reverse operation with use of a correction table for the corresponding sub-pixel position. Thus the measuring accuracy is improved for the edge direction and then the curvature of an edge picture element train is measured with high accuracy.

摘要： PURPOSE:To obtain a calibration value with a small error by performing a digital operation from the image of an object imprinted on a digital image and calibrating the internal parameters of a TV camera for restoring the position of a the object in the three-dimensional space. CONSTITUTION:The coordinate of the image of a gauge mark for calibration which is formed on a column where there is no distortion in the horizontal direction is measured. Data for calibration in the vertical direction is regressed to a regression equation expressing the relation between the three-dimensional coordinates of the gauge mark for calibration corresponding to the column and the coordinates of an image so as to calibrate the internal parameters for three TV cameras, that means, the distance to the image, the distortion coefficient of the image and the vertical coordinate of the center of the image. The coordinate of the image of the gauge mark for calibration which is formed on a row where there is no distortion in a vertical direction is measured. Then, the data for calibration in a horizontal direction is regressed to a regression equation expressing the relation between the three- dimensional coordinates of the gauge mark for calibration corresponding to the row and the coordinates of the image so as to calibrate the width of an area on an image pickup surface corresponding to one picture element in an image memory and the horizontal coordinate of the center of the image. Thus, the calibration is performed with high accuracy even if extremely large distortion is induced by merely obtaining the data for calibration and performing a regression analysis.

摘要： PURPOSE:To permit an easy connecting operation and the reduction of a connecting length by attaching and fixing optical fiber cores to a fixing jig and cutting flush the connecting end faces then mounting the cores to a core fixing base of a welding and connecting machine and welding and connecting simultaneously the cores. CONSTITUTION:The optical fiber cores 1 are inserted into the insertion grooves 20 of the fixing jig 10 and a top cap 19 is attracted by a magnet 22 to the jig to clamp the cores 1. The jig 10 is imposed on the core fixing base 10 of the welding and connecting machine and a juncture 23 of the optical fibers is inserted into the V-groove of a V-groove base 13. The jig 10 and the juncture 23 are pressed and fixed by a core clamp 16 and juncture clamps 15. The juncture clamps 15 are so adjusted as to hold lightly the juncture and therefore the juncture 23 advances by slipping between the clamps when the core fixing base 11 is fed into the axial center direction. The axial alignment and space between the fibers 2 are checked with a fiber butting plate 14 and thereafter the plate 14 is lowered and an arc discharge is generated to weld the optical fiber end faces.
