Forward-viewing video animation of the borehole making use of the computer software the dedicated boa hole television camera in order to create the porous wall expansion image the image by treating

摘要

Topic The optical machine of the boa hole camera for porous wall expansion image creation and simplification of electronic equipment structure, it assures cost conversion low, makes easy to utilize the boa hole camera.SolutionsWith the boa hole camera where this device photographs the forward-viewing digital video animation of the boring borehole, obtains the porous wall expansion image that animation data with the image processing software, it is the boa hole camera which does the rotary amendment of direction decision and the camera in regard to image processing.Each LED illumination 20 around the CCD camera gradient the photographing window and the means which simplify the structure of optical system, inside, clearness conversion of the image is assured the cone of light from the camera head from several cm sufficient luminous intensity profit, making use of the glass lens whose at the same time field depth is deep by the fact that it applies to the porous wall ahead. Simplification 18 of structure is assured with this, making photographing window kamerahetsudo as a plane surface glass. Choice figure Drawing 1
