TUNNEL CRACK IMAGE PHOTOGRAPHING APPARATUS, TUNNEL CRACK IMAGE PHOTOGRAPHING METHOD THEREOF, AND TUNNEL CRACK IMAGE PHOTOGRAPHING SYSTEM INCLUDING SAME

摘要

Disclosed are a tunnel crack image photographing apparatus, a tunnel crack image photographing method thereof, and a tunnel crack image photographing system including the same. The present invention allows a camera to photograph a tunnel wall surface at a time point when the camera is stopped, so as to obtain a clear tunnel wall image. The tunnel crack image photographing apparatus comprises: a camera photographing the wall surface of a tunnel; a linear motor in which the camera is reciprocally mounted along the driving direction of an automobile; and a control unit which controls the linear motor by obtaining the speed of the automobile, calculating a shooting cycle of the camera using the speed of the automobile and a preset angle of view of the camera, and calculating the speed of the linear motor that causes the moving speed of the camera, calculated by adding the speed of the linear motor to the speed of the automobile for each shooting cycle, to be zero.;COPYRIGHT KIPO 2020
