method for estimating and correcting the vibration component in outdoor image captured by vertically installed in-vehicle line sensor is proposed. When outdoor image is captured with a line sensor while moving, vibration of a vehicle or equipment during moving causes periodical shifts in the image. Vertical shifts between every adjacent line are estimated using phase-only correlation technique which can estimate the parallel shift between two images in sub-pixel precision. Then, using the estimated shift-values, vibration component in the image is estimated using 1-dimensional discrete Fourier transformation and linear regression technique. The effectiveness of the proposed method was confirmed by experiments with images taken by vertically installed in-vehicle line sensor.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2020-08-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2020-AVM-110"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":206584,"updated":"2025-01-19T19:23:00.365527+00:00","links":{},"created":"2025-01-19T01:08:33.844967+00:00"}
