Problems solved by technology

However, the camera of this invention is located at the front of the vehicle, with a small collection range, and the top projection can only deal with overhead reconnaissance from the top, and cannot deal with side-view reconnaissance from the upper side, and side-view reconnaissance is also a reconnaissance method that adaptive camouflage camouflage needs to deal with.

Embodiment 1

[0059] combine figure 1 , an adaptive camouflage camouflage online design system, including two parts, a central computer and an image acquisition device. The image acquisition device can be an unmanned aerial vehicle platform, which is mainly composed of a data transmission module, an image acquisition module, a flight control module, and a platform power module. The information communication module mainly completes the transmission of information such as flight control instructions, image acquisition module control instructions, and image acquisition through wireless transmission technologies such as Bluetooth or wifi. The image acquisition module is composed of optical system, pointing device, detector, etc. It is responsible for collecting images of corresponding areas according to the image acquisition control instructions received by the information communication module, and providing image materials for camouflage camouflage design or camouflage effect evaluation; the f...

Embodiment 2

[0110] combine figure 2 , an adaptive camouflage online design method, comprising the following steps:

[0111] Step 1, collect the background area image, and determine the camouflage design candidate area;

[0112] Step 2, extract the main color information of the panoramic background image: take the collected overall background as the object, and use the color image main color fast extraction method to extract the main color of the background panoramic image with the number of colors to be implemented as the camouflage camouflage. Statistics of the proportion of each main color;

[0113] Step 3, determine the candidate background area of ​​the camouflage design;

[0114] Step 4, extract the main color information of the camouflage design candidate area: sequentially use the main color fast extraction algorithm of the color image to extract the main color and proportion information of the sample candidate area;

[0115] Step 5. Calculate the similarity between the candida...

Embodiment 3

[0171] The difference between this embodiment and Embodiment 2 is that it also includes:

[0172]Step 12, collect images for camouflage effect evaluation: use the UAV to collect background images containing targets according to certain specifications.

[0173] Step 13, evaluating the camouflage effect: the central computer receives the camouflage effect evaluation image, and evaluates the camouflage effect. If the camouflage effect does not meet the requirements, go to step 5 and select the next candidate area to redesign the camouflage camouflage; otherwise, the camouflage effect meets the requirements, the drone is recovered, and the camouflage design is completed. If the camouflage effects of all candidate area designs do not meet the requirements, the scheme with the best camouflage effect is selected as the final camouflage design scheme.

[0174] In step 12, the UAV platform collects images and collects at least five images in the following manner:

[0175] (1) Assumin...

Abstract

The invention provides an adaptive camouflage camouflage online design method and system. The method implemented by the system includes: collecting background area images in real time, determining camouflage design candidate areas, extracting background image and main color information of sample candidate areas; calculating each The similarity between the candidate area and the main color information of the background image and determine the background area of ​​the camouflage design; according to the principle of color proximity, determine the color of the camouflage implementation from the camouflage candidate colors; calculate the color of each pixel color in the candidate area and each main color of the background distance, and assign the color value of the nearest main color to the pixel to obtain the original image of the image camouflage design; use the mathematical morphology method to process the original image to obtain the main color patch map; the background in the main color patch map The main color is replaced with the closest camouflage color to obtain the camouflage design pattern, and the camouflage effect is evaluated and improved in real time after the camouflage is implemented, and the final camouflage design pattern is obtained.

Description

technical field [0001] The invention relates to a data identification technology, in particular to an adaptive camouflage online design method and system. Background technique [0002] Adaptive camouflage technology requires that after entering a certain environment, the equipment can change its surface camouflage color and pattern according to the color characteristics of the environment background in a short period of time, so as to realize the integration with the color and pattern characteristics of the environment. Therefore, higher requirements are put forward for the fast and accurate design of camouflage camouflage. For the adaptive camouflage design of maneuvering targets, it is necessary to complete the design of camouflage camouflage in time after the environmental characteristics of the target change, mainly involving the rapid acquisition of background images, the rapid extraction of main colors of background images, the determination of camouflage colors, and t...
