| 摘 要： | 目前,主流的激光点云数据模型仍以散乱点组织为主,且点云与模型分开组织。本文应古建筑激光点云处理建模的数据组织需要,通过点云、模型的关联组织和古建筑层次编码等方法,创建了古建筑激光点云-模型多层次一体化数据模型。并通过实例应用进行了验证,效果较好,为点云的复杂数据组织提供了借鉴。

| Abstract: | Laser scanning points,extracted models are often stored and organized separately in many software packages.This research intends to propose an integrated multi-layer data model to store and manage both point data and derived features and models.An experiment has been made in feature extraction and 3D modeling of an ancient building based on laser point clouds in which the effectiveness of the proposed data model has been confirmed. |
