手動作検出と連動した質感再現システムの開発(コンシューマ,映像メディアおよび一般)  [in Japanese] Development for appearance reproduction synchronized with hand detection  [in Japanese]

Abstract

我々は製造段階での作業に対する質感の変化を視覚的にシミュレーションする質感再現システムを開発している.目標とするシステムには作業と連動する質感再現が重要で,実作業,特に手動作との連携が必要不可欠である.そこで本研究では机上作業における手の位置と動作をロバストに計測する手法を開発した.手の位置の検出には赤外線のみを発するプロジェクタで投影した構造パターンを用い,机上から一定高さ以内の手の位置のみを検出することで,作業時のみの手の位置を検出することができる.また手動作判定に必要な手の形状計測には空間コード化法を用いたが,計測範囲を計算で求めた手の周辺位置のみと限定することで計測及び形状再構築の処理時間を飛躍的に削減することができた.本報告ではこれら画像処理的な手法と,試作したプロトタイプシステムの性能について述べる.

We have been developing a rapid proto-typing display system which can verify an appearance of final product in finishing and painting industry. In this system, it is necessary to measure detail information of hand position and shape to recognize the worker's instruction. Therefore, we apply a rapid hand measurement which combine a roughly detecting of hand position and shape by spatial encoding method with IR projection. For detecting of hand position, non-linearity interval strips are used for detecting objects that are lower than constant height. The interval of strips is devised in relation to an angle of camera axis to make equal the height in detecting. For detecting of hand shape, the spatial encoding pattern is projected only an area of hand position. The limited process with limited area is possible to reconstruct the shape of hand very fast. A practical result shows that the position and shape recognition is performed about one second.
