Document Type and Number:
WIPO Patent Application WO/2022/054412
Kind Code:
A1
Abstract:
The present invention addresses detailed observation of a change in a structure by using an image captured by a camera having high-performance specifications, the change being caused by heating and cooling of the structure to a temperature beyond the limit of the working temperature of the camera having high-performance specifications, and by returning to a normal temperature. An observation device for a structure is characterized by comprising: a camera casing that has a rectangular three-dimensional shape and that has a glass window formed from a heat-resistant and/or cold‐resistant glass on at least one surface of the three-dimensional shape; a heat-insulating wall covering the camera casing excluding the glass window; a fluid supply port and a fluid discharge port which are for circulating a cooling fluid or a heating fluid at least inside the camera casing, among inside the camera casing and inside the wall; and a camera that is disposed inside the the camera casing, captures a still image or a moving image of the structure outside the camera casing through the glass window, and externally outputs or internally stores data of the captured image.
