Abstract

The invention discloses a smoke screen interference efficiency obtaining method. The method comprises the steps: obtaining a first infrared image of a test scene in a smokeless screen environment anda second infrared image of the test scene in a smokeless screen environment; generating a first target array based on the first infrared image and generating a second target array based on the secondinfrared image; and generating a calculation model based on the first infrared image, the second infrared image, the first target array and the second target array, and calculating the effective shielding area of the smoke screen to obtain the smoke screen interference efficiency. According to the invention, a computer image processing mode is applied to external field smoke screen interference efficiency evaluation; the calculation model of the smoke screen interference efficiency based on the infrared image is established, accurate evaluation of an external field test target is achieved, andthe method has the advantages of being high in smoke screen interference efficiency evaluation precision, simple and easy to operate, objective, real and comprehensive in smoke screen interference efficiency evaluation and the like.

Description

technical field [0001] The invention relates to the field of smoke screen interference effectiveness evaluation, in particular to a smoke screen infrared interference efficiency acquisition method. Background technique [0002] At present, the evaluation methods of infrared interference effectiveness of smoke screens in the field environment are rather messy, and the experience of many successful applications in engineering has not been summarized and sublimated, which greatly restricts the research and development of smoke screen weapons. In the prior art, methods for obtaining smoke interference effectiveness can be divided into two categories: experimental test evaluation method and theoretical calculation evaluation method. [0003] According to the test environment conditions, the experimental measurement methods can be divided into three types: laboratory smoke box evaluation method, small and medium-sized wind tunnel evaluation method and field evaluation method. The...
