<p>PROBLEM TO BE SOLVED: To reduce time for detecting work and to reduce a risk of an accident by capturing a temperature difference between the mine and a ground surface by an infrared camera, and detecting the mine by utilizing a positioning member such as a laser marker or the like. SOLUTION: A positioning member made of a laser marker 1 or the like as a reference of position measuring is installed at a corner of an embedded mine detecting area, and an infrared laser mine detector 3 is installed near the detecting area. Water and a liquid nitrogen are scattered in the area, and the detecting area is photographed by an infrared camera. If there exist embedded mines 2 and scattered mines 4, a radiating cooling temperature is different in the case in which the embedding part is only soil, and hence a temperature difference is generated. Types or the like of embedded mine, unexploded bomb, scattered mine and installed mine are sorted, and analyzed. Then, a position of the mine detected by a GPS is substantially measured, and a detailed position by the marker 1 is measured. The mine embedded position is mapped together with input value information such as existing map graphic information or the like.</p> |
