The image-based measurement technique is one kind of novel noncontact measurement technique, which develops from the computer vision realm and primarily regards images as the carrier and means to detect or transfer the information. The image-based measurement technique can bring us the actual information of the examined object after dealing with the characters detected from the images.

基于图像的测量技术是从计算机视觉领域中发展起来的新型非接触测量技术，它主要是把图像当作检测和传递信息的手段或载体而加以利用的测量方法，通过提取图像的特征信号，最终从图像中获取被测对象的实际信息。

The sex pheromone of click beetle was reviewed from the terms of distilled, isolated and identified, and its application status in this paper, to provide a guidance for the study of it.

In this paper, I establish a set of updating the basic land-use map technology and flow after I go deep into studying the methods of updating the basic land-use map based on 3S technology. It is very important point that I bring forward some methods of change information automatic detected founding on land-use map unit, cross correlation analysis with multispectral image and object-oriented classification aiming at difference data and difficult identifying change information problems.

本文在深入研究了基于3S技术更新土地利用图件的方法基础上，从实用化的角度出发，建立了一套利用3S技术更新土地利用基础图件的技术流程与方法，并针对不同的数据情况和变化信息自动提取等问题提出了基于土地利用图斑单元的知识库变化信息自动发现方法、多波段遥感影像交叉相关分析变化识别方法及面向对象的遥感影像分类变化检测方法。

In general, there is lots of geographic information on it. Point symbols, linear symbols, area symbols and texts counterchange on topographic map. Description of Relations among graphs is very difficult. Besides, there is defectiveness in scanning and deformation of map.

从总体上看，地形图承载了大量的地理信息，各种点状符号、线状符号、面状符号、文字注记在空间上纵横交错、相互叠置，反映在地形图上的是图形目标间的关系难以描述，再加扫描技术的不完善等因素，这给图象的分割和要素的识别以及拓扑信息的提取带来了很大的困难。
