Problems solved by technology

[0006] The patent with the publication number CN107729830A introduces a method for detecting and calculating the camouflage effect based on background features, which uses the similarity between the camouflaged target and the original background without the target to represent the camouflage effect, so it does not involve the background area selection method, but the self-adaptive Camouflage needs to be evaluated against the background image with targets collected in real time. In addition, the invention does not specify the calculation method of specific indicators, nor does it discuss the efficiency of the algorithm. Therefore, this patent is difficult to meet the requirements for the evaluation of the camouflage effect of adaptive camouflage

Embodiment 1

[0061] combine figure 1 , an adaptive camouflage camouflage effect online evaluation system, including a central computer and an image acquisition device. Wherein, the image acquisition device may be an unmanned aerial vehicle platform, on which an image acquisition module, a flight control module, an information communication module, and a platform power module are arranged. The information communication module mainly completes the transmission of information such as flight control instructions, image acquisition module control instructions, and collected images 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 evalua...

Embodiment 2

[0120] to combine figure 2 , an adaptive camouflage camouflage effect online evaluation method, including the following steps:

[0121] Step 1, the unmanned platform lifts off: first control the image acquisition drone to lift off and initially maneuver to a reasonable area to prepare for image acquisition.

[0122] Step 2, collecting images: control the UAV to collect images of the specified background area at a suitable angle and field of view, and send the collected images back to the central computer through the information communication module. The image acquisition requirements are: control the image acquisition system of the UAV from the directions of 0°, 90°, 180° and 270° respectively (it is agreed that the direction of travel of the target is 0°, clockwise is positive), and five points directly above the target. The image is collected in azimuth, where the camera pitch angle is -90 degrees when collecting directly above (it is agreed that the pitch angle is 0 degre...

Abstract

The invention provides a self-adaptive camouflage effect online evaluation method and system, the system comprises a central machine and an image acquisition device, and the method comprises that: unmanned image acquisition equipment lifts off and acquires images of an area where a camouflage target is located through different angles in real time; a main color of the target and main colors of a plurality of background area images around the target are extracted; the spatial distribution information entropy of each main color in the target and background images are respectively calculated; thesimilarity between the target and the background image is calculated according to the difference between the spatial distribution information entropy of the target and the background and the main color, and the target camouflage effect in the single image is evaluated according to the similarity; and the camouflage effects of the target in the multi-angle acquisition images are integrated, and the self-adaptive camouflage comprehensive camouflage effect of the target is evaluated.

Description

technical field [0001] The invention relates to a data identification technology, in particular to an adaptive camouflage effect online evaluation method and system. Background technique [0002] After the adaptive camouflage is implemented on the maneuvering target, it is necessary to quickly complete the evaluation of the camouflage effect to judge whether the target can be better integrated into the background after the camouflage; Wasteland background with earthy yellow as the main color, etc.), it is also necessary to evaluate the camouflage effect to judge whether to redesign the adaptive camouflage according to the current background. Therefore, it is necessary to quickly complete the effect evaluation of adaptive camouflage. [0003] "Evaluating Target Visible Light Camouflage Effect Based on Comprehensive Color and Distribution Information" (Liu Zunyang, Infrared and Laser Engineering, 2012.4) proposed a method to evaluate the camouflage effect by using the target ...
