The invention discloses a camouflage pattern design method capable of quickly adapting to battlefield changes. The method comprises the following steps: collecting a plurality of battlefield images byutilizing an unmanned aerial vehicle; based on a CNN convolutional neural network method, establishing a style image synthesis network model, and pre-training the style image synthesis network modelby using a VGG19 model; simplifying the color space of the composite style image according to the used cloth dye, and forming a camouflage pattern from the composite style image. According to the method, through collecting a plurality of real-time battlefield images by using an unmanned aerial vehicle, color combinations and texture modes which are most similar to battlefield backgrounds are rapidly generated through a computer image synthesis technology, the camouflage performance of camouflage patterns can be improved to the maximum extent, the designed camouflage pattern content images arehigh in richness and can adapt to actual battlefield scenes with variability, and the camouflage safety of soldiers or equipment can be improved.
