Abstract

In the process of airborne remote sensing monitoring,zoom lens is widely used and altitude is frequently changed.The airborne images of different resolutions are got.Therefore,to mosaic the quick views of different resolution for real-time monitoring is needed.A new method to solve the problem is proposed.This method uses quartering theory to split images,detects zooming ratio,and selects registration strategy.Then SURF(Speeded-Up Robust Features)algorithm is applied to mosaic images.It can be used to get a mosaic image under the condition of continuous zooming with focal distance ranging from high power to low power or from low power to high power.The mosaic experiments of zooming airborne images and zooming ground images indicate this new method can be used to mosaic images with different resolutions,and the results are all based on the highest resolution.

不同地面分辨率图像的拼接方法

在航空遥感监测过程中，变焦镜头应用广泛，高度变化频繁。得到了不同分辨率的航空图像。因此，需要对不同分辨率的快速视图进行拼接，实现实时监控。提出了一种解决该问题的新方法。该方法利用四分理论对图像进行分割，检测放大比例，选择配准策略。然后将SURF(accelerated - up Robust Features)算法应用于拼接图像。它可以在从高功率到低功率或从低功率到高功率的焦距范围内连续变焦的情况下获得拼接图像。对机载图像和地面图像的缩放拼接实验表明，该方法可用于不同分辨率图像的拼接，且拼接结果均以最高分辨率为基础。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
