<p><P>PROBLEM TO BE SOLVED: To provide a geological survey method to photograph images including azimuth and positional information by using a simple borehole camera device without azimuth or depth sensor. <P>SOLUTION: In the geological survey method for photographing images of a wall surface of a borehole by inserting a probe, which incorporates a camera therein and constitutes a borehole camera device, into the borehole, a plurality of transparent pipes each having a prescribed length and a colored straight line extending in the lengthwise direction are connected together such that the colored straight lines of the transparent pipes are aligned, and inserted into the borehole; and the probe is inserted into the connected transparent pipes, and, as the probe is lowered in the borehole, multiple 360°images of the borehole wall surface overlapped by the colored straight lines of the transparent pipes are photographed by the camera incorporated in the probe. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
