摘要:可量测实景影像(DMI)是目前国内针对采集空间信息需要开发的一种新技术,其主要由开发包、外方位元素描述文件、立体影像对组成,可以实现对空间立体影像进行信息测量、提取,并且可以与其它地理信息基础产品进行有效的兼容。DMI是一种针对与地面近景的可量测影像,可以通过人的角度来提供包括城市地形信息、环境信息、建筑外立面信息、城市部件信息等非常详尽的城市立面图。其直接以高分辨率、高清晰度的影像来呈现出物体对象最原始的数据信息。本文作者根据多年关于可量测实景影像的实践经验,从可量测实景影像的功能及其应用领域对DMI进行了初步研究与探讨。

Abstract: measurable imaging image (DMI) is the present domestic for acquisition space information need to develop a new technology, which is caused by setups, foreign a element file, stereo images described for composition, which can make the space stereo image information measurement, extraction, and can be and other geographic information based products effectively compatible. DMI is a kind of to the ground of the magic measurable image, through the perspective of people can provide information, including urban terrain environment information, building facade information, information is very detailed urban parts of the city elevation. The direct to high resolution, high resolution images of objects to present the most primitive data object information. In this paper the author about measurable imaging image of experience, measurable imaging images from the function and application field of DMI makes a preliminary study and discussion.

前言
随着经济的迅猛发展,科学技术的飞速前进,城市的现代化、信息化建设也迈开了步伐。可量测实景影像(Digital Measurable Image),简称DMI,是目前国内针对采集空间信息需要开发的一种新技术,其主要由开发包、外方位元素描述文件、立体影像对组成,可以实现对空间立体影像进行信息测量、提取,并且可以与其它地理信息基础产品进行有效的兼容。一般情况下,DMI是通过道路移动测量系统进行采集数据得到的,同时,DMI还可以与4D地理信息基础产品进行集成兼容,这无疑对目前国内4D技术是一种有效的补充。可量测实景影像是一种针对与地面近景的可量测影像,这也是与4D开发系统最大的不同之处。……
