自動車のサイドミラーやエンブレム、家電製品・スマートフォンのフレームなどに使われる鏡面部品は、きらびやかで高級感がありますが、その反射性ゆえに表面欠陥の自動検出が困難という課題があります。本研究では、縞状の光を部品表面に投影し、その模様の変形をAIが解析することで欠陥を検出する技術を開発中です。縞模様画像の蓄積とAIによる学習を通じて、検査精度の継続的な向上が期待されています。

完全自動運転ではなく、運転の楽しさを残しながら安全性を高める支援システムを目指しています。運転中のあくびなどの“予兆”行動を車内カメラで捉え、ドライバーの癖や行動パターンをAIが学習。個人に最適化された支援を提供することで、安全かつ快適な運転環境を実現します。

中小企業の多くでは、いまだ人の目による検査が主流ですが、技能や評価基準には個人差が生じやすい問題があります。この課題に対し、検査員の技能をAIで可視化・数値化する評価システムを開発しています。これにより、上司の心理的負担を軽減しつつ、公平で納得度の高い技能評価が可能になります。

近年、自然災害の増加に伴い、橋梁やトンネルなどのコンクリート構造物に欠損が生じるケースが増加しています。これらの構造物は経年劣化により強度や外観の維持が困難となるため、定期的な点検と迅速な修復対応が求められます。従来の点検作業は主に目視に頼っており、点検者の熟練度に依存することで、評価のばらつきや見落とし、作業負担の増大といった課題が生じています。そこで本研究では、画像処理技術やLiDAR技術を活用し、点検作業の効率化および精度向上を目的とした技術開発に取り組んでいます。

人間の耳は2つなのに、コミュニケーションロボットには3つ以上のマイクが搭載されていることが一般的です。「2つのマイクで人間と同じように聞き分けることは可能か？」という問いから始まり、複数話者の音声や残響のある環境下でも目的の音声を抽出するロボットの聴覚システムの研究に取り組んでいます。課題は多いものの、引き続き実験と改良を重ね、実用化に近づけていきたいと考えています。
