在不同光照和旋转角度下进行地理特征遥感识别是测绘领域的难点,为了实现对地理地形的准确测绘,需要进行地理特征遥感识别优化设计.传统方法中,采用遥感图像边缘特征检测算法,当遥感图像出现旋转角度时,识别性能不好.针对这一问题,提出一种角点检测的地理特征遥感识别算法,并进行系统设计与实现,系统通过图像传感模块采集遥感图像,经过角点特征处理器提取图像特征.在不同光照和旋转角度,采用单尺度Harris角点检测算法对图像进行检测并提取角点,得到地理遥感特征数据采集的角点模型,基于角点检测,进行遥感识别算法改进和系统实现.实验结果表明,采用该算法和系统,地理特征遥感识别准确率高,耗时较少,提高对地理特征遥感识别性能.为实现对地理地形的准确测绘提供依据.

In a different light and rotation angle of remote sensing identification of geographic feature is difficult field of Sur-veying and mapping, in order to achieve accurate mapping of the geographical terrain, the need to optimize the design of geographical features of remote sensing recognition. Put forward the geographical characteristics of a corner detection algo-rithm in remote sensing recognition, and system design and implementation, the system through the image sensing module for acquisition of external image after color processor, image feature extraction. Under different illumination and rotation an-gle, using the single scale Harris corner detection algorithm for detection and extraction of image corner, corner get geogra-phy remote sensing characteristics of data acquisition model based on corner point detection, remote sensing recognition al-gorithm is improved and the system realization. The experimental results show that using this algorithm and system, remote sensing identification geographical features high accuracy, less time consumption, improve on the performance of the geo-graphical features of remote sensing recognition. It can provide the basis for realizing accurate mapping of the geographical terrain.
