7 results about "Camouflage" patented technology

Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see (crypsis), or by disguising them as something else (mimesis). Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of actively changing their skin pattern and colours, whether for camouflage or for signalling. It is possible that some plants use camouflage to evade being eaten by herbivores.

Method and system for evaluating dynamic camouflage effect of target

The invention belongs to the field of video detection, and particularly relates to a method and system for evaluating the dynamic camouflage effect of a target. According to the scheme, the method comprises the following steps: acquiring information, cleaning data, loading an obtained video clip, and marking a real mask of a target in a video frame by frame; loading the obtained video clip, skipping to a first frame where the target to be analyzed appears, marking the target to be analyzed, and marking a start frame number and a stop frame number of the target to be analyzed; carrying out reading, feature extraction and feature processing on the whole target clip video, outputting result features and converting the result features into a prediction mask of a target; and calling a visual detection index evaluation tool, loading a real mask of the target, processing high-dimensional data information, and calculating to obtain a camouflage quantitative score. The method and the device provided by the invention can effectively identify the dynamic camouflage effect of the target, and have practical application values in the fields of computer vision, military confrontation technology development, camouflage animal ecological protection, camouflage animal behavioral research and the like.

Multi-band imitated vegetation composite camouflage material based on multiple cooling modes and preparation method thereof

The application discloses a multi-waveband imitated vegetation composite camouflage material based on a multiple cooling mode and a preparation method thereof. The material comprises a high-hygroscopic camouflage base material, a high-reflective filler, phase change microcapsules and an additive. The high-hygroscopic camouflage base material not only serves as a matrix of various fillers and simulates the transpiration cooling effect of plants, but also, in combination with green pigments, can form a similar reflection spectrum to green plants; the high-reflective filler improves the reflectivity of the camouflage material in the visible light-near infrared-mid-infrared waveband, thereby realizing a radiation cooling effect; and the phase change microcapsules have a relatively high phase change enthalpy at normal temperature, thereby further reducing the overall temperature difference between the material and the environment background. The composite camouflage material is highly similar to green plants in the solar spectrum waveband, has a high correlation coefficient of 0.9778, can realize the same color and the same spectrum, and has a relatively low radiation temperature characteristic in the mid-infrared waveband. The camouflage material is expected to realize multi-waveband compatible camouflage in a vegetation background.
