FlexibleARulerは、カメラを使って距離・角度・軌跡・曲率指数を測るAR定規です。画面中央の照準を対象に合わせ、点を追加したり表面をなぞったりして測定できます。 【4つの測定モード】 ・距離:始点と終点を指定して、2点間の距離を測定。 ・角度:始点・頂点・終点の3点から角度を表示。 ・軌跡:表面をなぞった経路の長さを記録。 ・曲率:始点の平面に沿って曲線を記録し、曲がり具合を曲率指数で表示。結果には三角形の補助線も表示します。 【結果を保存・共有】 測定結果を履歴で確認できます。測定箇所と数値ラベル、結果カードをまとめた画像を写真に保存したり、共有したりできます。終点を取り直して測定結果を更新することもできます。 【使いやすい測定操作】 ・メートル、センチメートル、インチの切り替え ・距離・角度測定時の3倍拡大ガイド ・表面検出と測定状態に応じた操作ヒント ・触覚フィードバックとサウンド ・ライト、平面・特徴点の補助表示 ・クイックガイドと測定のコツ iPhone・iPadに対応。アカウント登録や広告はありません。測定履歴は端末内に保存されます。 AR測定には対応する実機のカメラが必要です。測定値は参考値で、光の状態、表面の材質、端末の動きなどによって変わります。
