TL;DR: In this paper, a sea explosion height measuring apparatus is provided to decrease an error in the measurement by calculating an explosion height by recording an explosion image and material processing image and then recognizing geometrical information thereof automatically and semiautomatically.
Abstract: PURPOSE: A sea explosion height measuring apparatus is provided to decrease an error in the measurement by calculating an explosion height by recording an explosion image and material processing image and then recognizing geometrical information thereof automatically and semiautomatically. CONSTITUTION: A sea explosion height measuring apparatus includes an image photographing part(110) mounting a zoom lens(111) for photographing an image of a long-distance object and converting the photographed image into an electric signal, an image display part(130) displaying the photographed image on a screen, an image recording part(140) recording a peculiar number of a test bomb by a speech and the electric signal at a tape, an image conversion part(120) converting the electric signal to be suitable for the image display part and the image recording part and transmitting the converted signal to the image display part and the image recording part, an image reproduction part(160) reproducing image data recorded at the tape, and an explosion height calculation part(170) storing the reproduced image signal at an auxiliary memory device and processing the image signal for calculating the height of sea explosion.

TL;DR: In this paper, the problem of forming a projecting image in a radiation projecting image forming device utilizing a focal surface image forming means forming a focal image in the scanning beam type radiation image forming devices.
Abstract: PROBLEM TO BE SOLVED: To easily form a projecting picture in a radiation projecting image forming device utilizing a focal surface image forming means forming a focal surface image in a scanning beam type radiation image forming device. SOLUTION: This device scans the entire surface of the target surface of a target collimator part 16 by an electron beam L1 and successively radiates an X-ray beam L2 toward a subject 9 from each collimator hole 17. An X-ray L2 transmitted through the subjected 9 is detected by a radiation detecting element and a focal surface image forming means 31 obtains focal surface image data D2 on each of a plurality of focal surfaces existing between a radiating detector 20 and the holes 17. An image conversion processing means 32 gives interpolating processing such as the correction of a magnification, the conversion of pixel density to each focal surface picture to adjust the position of pixels. A projecting image forming means 33 adds pixel values at the same pixel position of each focal surface image to each other to form the projecting image of the subject 9.

TL;DR: In this article, a mirror is installed in between each plurality of cameras, and an image processing unit connects a plurality of images to a single wide angle image by one lookup processing process at once.
Abstract: PURPOSE: An image processing device producing an image of wide angle and a method thereof are provided to perform image conversion for obtaining a single wide angle image by one lookup processing process at once. CONSTITUTION: A mirror(114,115) is installed in between each plurality of cameras(111~113). A receiving unit(12) receives a plurality of capture images of a plurality of cameras. An image processing unit(14) revises a distortion in a plurality of images through a lookup table. An image processing unit projects a phase of a subject in a plurality of images on a plane. An image processing unit connects a plurality of images to a single wide angle image. An output unit(15) outputs an output image.

TL;DR: In this article, a motion pattern analysis method using a panoramic image was proposed to separate a series of work procedures to be separated by motion elements using a motion element separation step.
Abstract: The present invention relates to a motion pattern analysis method using a panoramic image and, more particularly, to a motion pattern analysis method using a panoramic image in which work procedures of a worker in a work site are photographed from the perspective of the worker, the photographed procedures are made into a panorama and then the panorama is analyzed to allow a series of work procedures to be separated by motion elements The present invention comprises: a work photographing step for photographing work procedures of a worker using a camera installed in a helmet worn by the worker; an image conversion step for converting an image photographed in the work photographing step into a panoramic image; a hand movement analysis step for extracting the worker's hand movement from the converted image and analyzing the extracted hand movement; an image separation step for separating the image by repetition cycles of the hand movement analyzed in the hand movement analysis step; and a motion element separation step for further separating, by motion elements, the image separated by the repetition cycles
