Abstract

路面状態に関する情報はドライバが走行上の安全を確保するために不可欠であり,運転環境の計測・理解において重要な要因の1つである.本論文では,画像より抽出した路面状態に関する特徴量と気温を基に,統計解析により5種類の路面状態を判別する手法について提案する.本方式は路面状態を表す特徴として,路面上の水分および路面上に積った降雪成分に注目し,路面上の水分に対しては偏光特性,路面上に積った降雪成分に対してはテクスチャに関する特徴量を画像より抽出し,これら特徴量と気温の情報を基に,マハラノビス汎距離最小に基づく多変量判別分析法により路面状態の判別を行うものである.また,本提案方式を実際のフィールドにおいて収集した路面画像に適用し,その有用性についての検証を行う.Understanding of vehicle driving environment based on the road condition,and weather,etc.,is necessary to secure safe and smooth transport facilities.The road condition is one of the most important factors toward understanding of vehicle driving environments.A new algorithm for discrimination of the road condition has been described in this paper.This algorithm employs a multivariate analysis to discriminate the road condition based on temperature as well as features of the road extracted from image.We conducted field tests to verify the accuracy of this algorithm and obtained favorable results.

Understanding of vehicle driving environment based on the road condition, visibility and weather, etc., is necessary to secure safe and smooth transport facilities. The road condition is one of the most important factors toward understanding of vehicle driving environments. A new algorithm for discrimination of the road condition has been described in this paper. This algorithm employs a multivariate analysis to discriminate the road condition based on temperature as well as features of the road extracted from image. We conducted field tests to verify the accuracy of this algorithm and obtained favorable results.
