Title: Sensing system for collapse of slope using thermo-graphic camera
Inventor: YOON WON SUB
IPC: G08B21/18
Filed: 2019-12-30
Abstract: The present invention relates to a slope collapse detection system using a thermal imaging camera. By photographing a sensing pile installed on a slope surface with a thermal imaging camera to detect a change in the position of the sensing pile, a separate wire connecting the sensing pile is unnecessary, and thus it is possible to reliably measure the change state of the surface of the slope without problems such as deformation or damage to the wire caused by wild animals. In particular, by performing photographing with a thermal imaging camera, even if there is fog or other fine foreign matter around the sensing pile, it is possible to accurately capture the sensing pile. The present invention can accurately detect a position change of the sensing pile. In addition, by attaching a separate heat source to the sensing pile, it is possible to more accurately measure the change in the mutual distance for a plurality of sensing piles using the heat source as a reference point on the thermal image. It is possible to more accurately predict the probability of collapse of slopes.
