Recently, with the development of range sensor, register and integration of multiple range images have gained more and more concerns and have been applied in many domains such as CAD reverse engineering, ill product detection, and non- contact measurement of 3D human body.
近几年来，随着距离传感器技术的进步，多视点距离图象的对准和集成问题已引起了人们极大的关注，并且在CAD反向工程、不良产品检测、整形外科手术规划以及人体三维尺寸的非接触测量等领域有了广泛地应用。
So this article introduces a kind of reasonable computing model, and applies it to calculating the sight distance that provided by crest vertical curves, moreover integrates it and method of PVSD to specify from quantity the principle of combining plane and vertical curves which belong to the freeway of plain district.
故本文引进一种较为合理的计算模型,来计算凸竖曲线上所能提供的视距,并结合PVSD法来具体量化平原区高速公路平曲线和凸竖曲线的组合原则,以期得到视觉效果最佳的立体线形。
