<p><P>PROBLEM TO BE SOLVED: To provide a drilled cavity bending degree measuring apparatus and drilled cavity bending degree measuring method using it which can measure the bending degree of a drilled cavity having an out-of-sight shape because of its relatively small diameter and the presence of bend without being affected by the internal environment of the drilled cavity, without requiring time and effort, simply, and accurately. <P>SOLUTION: The drilled cavity bending degree measuring apparatus includes: a hollow tubular body 20 which is inserted into the drilled cavity and bent in accordance with the bending degree of the drilled cavity; a laser emission part 22 which is placed on one end side of the tubular body 20 to apply laser light toward the other end side of the tubular body 20; a screen 24 which is placed on the other end side of the tubular body 20 and to which the laser light from the laser emission part 22 is applied; a photographing means 26 which is placed on the other end side than the screen 24 to photograph the screen 24; a transmission means 28 for transmitting the photographed data of the photographing means 26; and a controller for calculating the positional deviation of the end of the tubular body 20 on the basis of the transmitted photographed data. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
