Description
検出モジュール104は、画像プロジェクタ102に電気的に連結される。検出モジュール104は、投射面「P」の距離や、テクスチャ、色などを検出又は決定するように構成される、放射検出器ユニット112(EDU)を含む。EDU112は、様々な強度および波長の光線を放射および検出するように構成される。EDU112は投射面「P」を光で走査し、投射面「P」の特性に関する情報を計算する。これらの特性に、投射面「P」と画像プロジェクタ102との間の距離、投射面「P」の色に関する情報、および投射面「P]のテクスチャ又は粗さに関する情報(例えば、表面の不均一性、等高線、または凹凸)を含めてもよい。この情報は検出モジュール104からプロセッサ106に伝送される。CCD、ディジタルカメラ、または光学式走査技術を利用して、投射面「P」に関する特性を取得することができる。
