摘　　要：由于建筑三维图像信息提取系统存在信息提取丢帧率较高、测量结果与实际数据误差较大、三维图像信息提取效果较差等问题,故以增强现实技术为基础,设计一个建筑三维图像信息提取系统。硬件方面,设计可编程片上模块、电源处理模块、通信模块、HDMI接口,实现建筑三维图像信息提取系统的稳定运行。软件方面,采用增强现实技术提取建筑三维图像信息,并量算空间距离,构建尺度空间对大场景离散建模,实现建筑三维图像信息提取。实验结果表明,系统信息提取丢帧率低、三维信息测量准确性高,且具有较好的三维图像信息提取效果,说明系统具有一定实用性。Due to the problems of building 3D image information extraction system,such as high frame loss rate of information extraction,large error between measurement results and actual data,and poor effect of 3D image information extraction,a building 3D image information extraction system is designed based on augmented reality technology.In terms of hardware,programmable on-chip module,power processing module,communication module and HDMI interface are designed to realize the stable operation of building 3D image information extraction system.In terms of software,augmented reality technology is used to extract 3 d image information of buildings,and space distance is calculated to construct scale space for discrete modeling of large scenes,and 3 d image information of buildings is extracted.Experimental results show that the system has low frame loss rate,high accuracy of 3D information measurement,and good 3 d image information extraction effect,indicating that the system has a certain practicality.
