用线特征摄影测量对目标体素进行量测和重建的可行性研究

本文利用线特征摄影测量方法对ＣＡＤ实体造型中体素进行自动量测与重建、借此建立ＣＡＤ与数字摄影测量的桥梁，文中提出了一种以描述体素几何元素为未知数，直接在像片线特征与物体表面之间进行匹配的线特征摄影测量模型和方法，并对其可行性进行了实验，实验结果表明：线特征摄影测量能达到立体摄影测量相同的，甚至更高的精度，从而可解决无明显目标点工点物体的自动量测。

A FEASIBILITY STUDY ON MEASUREMENT ANDRECONSTRUCTION OF OBJECT PRIMITIVESUSING LINE PHOTOGRAMMETRY

:In this paper a bridge between CAD system and digital photogrammetryusing line photogrammetry is built up for automatic measurement and recons-truction of primitives in CAD.The mathematic models and algorithms are pre-sented. The geometric parameters of represented primitves are considered as un-knowns and a direct matching based on line features between image space andobject surface is suggested. The test results show that the precise of suggestedmethod is the same or even higher than which from standard stereo photogram-metry.
