Flexible calibration method for microscopic structured light system using telecentric lens.
This research presents a novel method to calibrate a microscopic structured light system using a camera with a telecentric lens. The pin-hole projector calibration follows the standard pin-hole camera calibration procedures. With the calibrated projector, the 3D coordinates of those feature points used for projector calibration are then estimated through iterative Levenberg-Marquardt optimizati...
متن کاملAcquisition of Light Rays Using Telecentric Lens
コンピュータグラフィックス(CG)や 3次元画像通 信の分野では,3次元空間の情報をいかに記述するかが 問題となる.従来は,ポリゴンなどの幾何形状モデルを 用いるのが一般的であったが,近年では,形状情報を持 たずに,多数の画像の変形や貼り合わせなどの処理によ り新たな画像を生成するイメージベースレンダリング (IBR)の手法が注目されている.さらに,IBRを一般 化した概念として,3次元空間情報を,その中の物体な どから発せられる光線の情報(以下,単に光線情報と記 す)として記述する手法が提案されている . 実空間を対象とする場合,従来は,透視投影 (perspective projection)の画像が得られる通常のカメ ラで撮影された多眼画像を,光線情報として扱ってき た .しかし,光線として記述される 3次元空間の情報 の本質は正投影(orthogonal projection...
متن کاملNovel method for structured light system calibration
Peisen S. Huang, MEMBER SPIE State University of New York at Stony Brook Department of Mechanical Engineering Stony Brook, New York 11794 E-mail: [email protected] Abstract. System calibration, which usually involves complicated and time-consuming procedures, is crucial for any 3-D shape measurement system. In this work, a novel systematic method is proposed for accurate and quick cal...
متن کاملMethod for large-range structured light system calibration.
Structured light system calibration often requires the usage of a calibration target with a similar size as the field of view (FOV), which brings challenges to a large-range structured light system calibration since fabricating large calibration targets is difficult and expensive. This paper presents a large-range system calibration method that does not need a large calibration target. The prop...
متن کاملA Flexible Calibration Method Using the Planar Target with a Square Pattern for Line Structured Light Vision System
A flexible calibration approach for line structured light vision system is proposed in this paper. Firstly a camera model is established by transforming the points from the 2D image plane to the world coordinate frame, and the intrinsic parameters of camera can be obtained accurately. Then a novel calibration method for structured light projector is presented by moving a planar target with a sq...
