3Dオブジェクトを選ぶだけで、自動的にROI範囲が決まる!

📷 監視カメラや自動運転システムでは、カメラから3D空間を見ているんです。「あの車を追跡したい!」と思ったとき、その車の3Dバウンディングボックス(直方体)を2D画像に投影すれば、自動でROI矩形が出てきます。

このデモでは、3Dシーンの中のオブジェクトをクリックするだけで、どのピクセル範囲を高画質にすべきかを自動計算します。カメラを動かしても、投影結果がリアルタイムで追従します 🎯

🖱️ Step 1 — 高画質に残したいオブジェクトをクリック

🌀 マウスドラッグでカメラを回転、ホイールでズームできます。気になるオブジェクトをクリックすると、赤枠(ROI)が自動で計算されます
