There is an existing method for estimating shooting distance with single camera called Motion Stereo that calculates by the difference of the onscreen object positions taken at different two points. The accuracy of the shooting distance depends on the accuracy of the distance between the two shooting points. In Motion Stereo by the camera on the smartphone, it is necessary to use the accelerometer for measuring the moving distance. However, the accelerometer always has error range. Then, we propose a new Motion Stereo that estimates the shooting distance by two kinds of ways; vertical and horizontal component of the camera motion. In order to improve the estimation accuracy by removing a component including a large error, the proposed method calculates the weighted average of two kinds of shooting distances. The experimental results show that the proposed method reduces estimation errors 8% less than existing Motion Stereo and avoids extreme dropping of the accuracy.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"79","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌数理モデル化と応用（TOM）"}],"bibliographicPageStart":"70","bibliographicIssueDates":{"bibliographicIssueDate":"2017-07-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"10"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:50:19.199496+00:00","id":182737,"links":{}}
