Range-image is one of a useful data for the recognition and localization of freeform 3-D object. Most recognition and pose-detection methods from range-image have to use a feature extraction, but it is necessary a simply model and difficult to extract features. Besides central to this issue is the problem of feature matching on the object and range-image. So we proposed use of appearance-matching technique on the range-image. To use range image for the appearance-matching has one more advantage. Range-image expresses a geometrical object information. So, it is easy to make range-image from polygon data to using camera-parameter, and large numbers of sample images from reality measurement are not necessary. In the fact large number of sample is the key to use appearance-matching. In this paper we propose a methodology for the recognition and pose-detection of freeform 3-D object by appearance-matching on the range-image.

　View Summary

An application of the pose detection using range images usually uses characteristic matching of the geometrical model but this method has two problems: selecting characteristics from range images is difficult
and it is difficult to make a geometrical model for a complicated shape. Previously a parametric eigen-space method was proposed for pose detection. This method makes object recognition and pose detection possible, but this parametric eigen-space method has a problem that intensity-images depend on a variety of light conditions therefore learning images must include variation of light conditions. © 1996 IEEE.

我々の開発したシリコンレンジファインダ(以下,SRF)はビデオカメラ以上の速度で距離画像を計測することの出来るデバイスであり,ビジュアルフィードバック等の動距離画像処理分野での応用が期待されている.このような3次元デバイスを実応用するためには柔軟性の高いキャリブレーション手法が必要であり,これまでにシステムパラメータによる方法が利用されてきた.しかしSRFは専用チップによりレーザ光を受光するため,シーンの明暗を計測することが出来ない.そのためプリズムを用いて同一レンズを通した画像を撮影することでカメラ系のキャリブレーション問題を解決した.また,プロジェクタ系に回転ミラーを用いているために,透視変換に基づく方法であるシステムパラメータ法を用いることが出来ない.そこで仮想スクリーンという概念を導入し,ミラーの回転角をプロジェクタ座標に補正することでシステムパラメータ表現を実現した.SRFをシステムパラメータによりキャリブレーションすることにより,各種応用分野への柔軟な対応が可能となった.
