Embodiment 1
[0065] 1. Use the DJI Phantom 4 drone to take aerial photos of 20 woodland background photos and 20 ocean background photos, among which the woodland background photos were taken in a certain area in the south, see image 3 (b), taking a photo of the ocean background in a certain sea area in the north, see image 3 (a). The altitude and distance of the aerial photography are about 0-100 meters, the grazing angle of incidence is not greater than 45°, the aerial photography direction is within 30° to the left and right of the light direction, the sun altitude angle is greater than 30°, and the atmospheric visibility is more than 10 kilometers. There is no exposure and noise in the picture . Aerial background photos such as image 3 shown.
[0066] 2. Use image processing software Photoshop to design large spot camouflage and natural texture camouflage; use Matlab software and original background photos to automatically generate digital camouflage. The design of the three cam...

The invention belongs to the cross technical field of computer technology and military engineering camouflage technology, relates to a camouflage camouflage effect detection and calculation method based on background features, which can be used for camouflage camouflage effect detection and calculation of military targets under various typical background environments. The invention uses structure, color, texture and statistics to represent the similarity between the target and the background. In order to objectively and accurately evaluate the effect of camouflage camouflage, an index based on fuzzy clustering method combined with information entropy and statistical features is designed. The weight distribution algorithm is used to determine the weight value of each index and calculate the weighted similarity between the target and the background. This method avoids too single evaluation index and the influence of subjective factors in weight distribution, and the calculated similarity result is very close to the result of human visual observation, and the error between the two is less than 5%, which effectively quantifies the detection of camouflage effect Evaluation results.
Description
technical field [0001] The invention belongs to the cross technical field of computer technology and military engineering camouflage technology, relates to a camouflage camouflage effect detection and calculation method based on background features, which can be used for camouflage camouflage effect detection and calculation of military targets under various typical background environments. Background technique [0002] In military engineering camouflage, camouflage camouflage technology is often used to blur the edge between the camouflaged target and the surrounding background, making it blend into the background, thereby reducing the risk of being discovered and attacked. Large spot camouflage and natural texture camouflage are the camouflages used in the early days. With the development of computer technology and digitalization of military operations, digital camouflage has been widely used in military target camouflage. As a commonly used camouflage technology at presen...
