A Camouflage Effect Evaluation Method

Abstract

The invention relates to a camouflage camouflage effect evaluation method, which comprises the following steps: making camouflage material photos of different posture profiles of human figures; making various background material photos; randomly inserting camouflage material photos into preset background material photos One of the 4 to 8 search positions to make a photo to be evaluated; select observers, and make each observer familiar with the experimental process; make each observer judge the different postures of the human figure in the photo to be evaluated within the specified time What kind of posture is the outline, and the judgment result is fed back to the computer. The computer calculates the average judgment accuracy rate and the average reaction time of each camouflage to be evaluated in different background environments. When a camouflage to be evaluated is in a certain If the correct rate of judgment in this background environment is low and the average reaction time is long, the camouflage effect of the camouflage to be evaluated is good in this environmental background; otherwise, the camouflage effect is poor. The invention not only has simple operation, low cost and wide application background, but also can effectively improve the accuracy of the experimental results and effectively increase the comprehensiveness of the experimental results.

Description

technical field [0001] The invention relates to a camouflage effect evaluation method, in particular to a camouflage camouflage effect evaluation method. Background technique [0002] The rapid development of modern weapons and equipment has led to "discovery and destruction". Camouflage camouflage is a common combat camouflage for armies all over the world, and its camouflage effect is directly related to the battlefield survivability of fighters. Visible light reconnaissance is the most basic and most commonly used means of individual reconnaissance on the modern battlefield. Evaluating the camouflage effect of camouflage under visible light reconnaissance means is one of the main basis for the design and evaluation of camouflage clothing. [0003] At present, the evaluation methods of camouflage effect mainly include field test and laboratory test. The national military standard "GJB 452.3-1988 camouflage clothing optical camouflage performance and its test method camo...

AI Technical Summary

Problems solved by technology

This method has certain accuracy, but has the following disadvantages: First, the scene is specific, and in actual use, the camouflage uniform needs to provide camouflage in various specific backgrounds; second, it requires a large number of subjects and a large number of cooperating personnel , the cost of one experiment is high, and it is not suitable for screening and evaluating camouflage uniforms in the design stage; third, this method is a field test, which is easily affected by external light, visibility, weather conditions, etc., resulting in errors

Most of these evaluation methods have the following disadvantages: First, computer algorithms are used to simulate and evaluate the characteristics of camouflage camouflage and background, and there is a lack of observation and subjective evaluation by observers through the visual system. There are significant differences; the second is that different researchers use different algorithms and selected image correlation parameters, and the weights of different parameters are different, which has a greater impact on the result evaluation; third, researchers generally compare some images of camouflage and specific backgrounds Correlation parameters, lack of global comparisons
