Since inspection of sewer pipes is dangerous and expensive, a safe and low-cost method is required. To realize a safe and safe sewer screening for quickly locating damages points, we have been working on a drifting wireless network camera system that takes a video of the inside of a sewer pipe with a floating camera unit and transmits the video via wireless communication. In this paper, we propose a design of a floating camera for this camera system, a method for correcting the image rotation caused by the structure of the floating camera, and a method for detecting cracks in the captured video. We implemented the system and the methods and conducted experiments in a real sewer pipe. The results of the rotation correction of the video obtained by the camera achieve sufficient quality for sewer screening. The proposed crack detection method achieved 64.0% precision and 100% recall in experiments conducted in a experimental sewer pipe made by polyvinyl chloride.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"31","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌デジタルプラクティス（TDP）"}],"bibliographicPageStart":"22","bibliographicIssueDates":{"bibliographicIssueDate":"2022-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"3"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:18:12.812881+00:00","id":217746,"links":{}}
