【摘要】：遥感产业作为我国高科技新兴战略产业,已经在我国的军事政治、经济民生等方面起到了突出的贡献作用。地理空间信息数据是遥感产业的数据基础,是我国基础设施建设性资源,其重要地位不容小觑,同时大力发展地理空间信息数据的获取与处理速度,提高遥感专题产品的质量保证,提高遥感产业事业中从业人员的整体素质,也就成了遥感产业事业又好又快发展的首要任务,也是办好遥感产业事业的必经之路。如何提高遥感专题产品的质量问题也就成为了目前急需解决的关键问题。在整个遥感专题产品处理制作过程中,需要涉及多个人员对遥感影像进行操作,操作过程复杂又耗时,人们难免发生疲劳等情况,这样不能给遥感专题产品的质量提供良好的保障。数字水印技术是信息隐藏领域与多个领域交叉的信息安全技术,能够很好的应用到遥感专题产品的质量监督过程中,能够给遥感专题产品提供质量上的保障,为遥感产业事业提供坚实可靠的理论基础。本文先从遥感事业的发展、国内外数字水印以及遥感影像数字水印的发展现状的角度,对遥感影像数字水印做了总体概括。进而讨论了遥感影像与普通图像的区别与各自特点,以此为基础设计了空间域和变换域两种遥感专题产品中矢量文件的数字水印嵌入提取算法。最后对遥感影像数字水印追溯平台软件系统进行了详细介绍,包括软件界面设计以及后台数据库设计等,让读者能够更好理解遥感影像数字水印的需求与目的。
[Abstract]:As a new high-tech strategic industry, remote sensing industry has played a prominent role in military politics, economy and people's livelihood.Geospatial information data is the data base of remote sensing industry and the constructive resource of infrastructure in our country, and its important position should not be underestimated. At the same time, the speed of obtaining and processing geospatial information data should be greatly developed.To improve the quality assurance of remote sensing products and to improve the overall quality of the employees in the remote sensing industry is the first task of the good and rapid development of the remote sensing industry and the only way to run the remote sensing industry well.How to improve the quality of remote sensing products has become a key problem that needs to be solved.In the process of processing and making the special products of remote sensing, it is necessary to involve many people to operate remote sensing images. The operation process is complex and time-consuming, and people inevitably experience fatigue.This does not provide a good guarantee for the quality of remote sensing products.Digital watermarking technology is a kind of information security technology which intersects information hiding field and many fields. It can be applied to the quality supervision process of remote sensing thematic products and can provide quality guarantee for remote sensing thematic products.To provide a solid and reliable theoretical basis for remote sensing industry.This paper first summarizes the digital watermarking of remote sensing image from the perspective of the development of remote sensing, the development of digital watermarking at home and abroad as well as the development of digital watermarking of remote sensing image.Then, the differences and characteristics between remote sensing image and ordinary image are discussed. Based on this, a digital watermark embedding algorithm for vector files in spatial domain and transform domain is designed.Finally, the software system of remote sensing image digital watermarking tracing platform is introduced in detail, including software interface design and background database design, so that readers can better understand the requirements and purposes of remote sensing image digital watermarking.
