Abstract

The invention discloses a digital watermark generation method and system for remote sensing images and a control method therefor. The disclosed generation method comprises the steps of obtaining position relation information between at least two adjacent remote sensing images; setting a digital watermark type; setting digital watermark information; generating a first roulette digital watermark of a left-right digital watermark type on the two remote sensing images in the left-right position relation, and / or, generating a second roulette digital watermark of an up-down digital watermark type on the two remote sensing images in the up-down position relation, and / or, generating a third roulette digital watermark of a four-corner digital watermark type on the four remote sensing images of the four-corner position relationship, wherein the first roulette digital watermark, the second roulette digital watermark and the third roulette digital watermark all comprise digital watermark information. According to the scheme, the problems that the information writing amount is large and the position relation between the remote sensing images cannot be distinguished when digital watermarks are applied to a large batch of remote sensing images with position information can be solved.

Description

technical field [0001] The present application relates to the technical field of digital watermarking, in particular to a digital watermark generation method, system and control method for remote sensing images. Background technique [0002] Digital watermarking (Digital Watermarking) technology is to embed some identification information directly into digital carriers (including multimedia, documents, software, etc.), but it does not affect the use value of the original carrier. Through the information embedded in the carrier, the purpose of confirming content creators, buyers, transmitting information or judging whether the carrier has been tampered with can be achieved. Image watermarking is the most widely used application of digital watermarking, professional image processing software provides image watermarking function. In recent years, with the widespread application of satellite images and maps, the application of digital watermarking technology on remote sensing i...
