A fast control algorithm for digital camouflage spraying robot

The technology of digital camouflage is a new camouflage technique of military engineering. It has outstanding effect for counter overhead reconnaissance, which sprays many mosaics with different colors on camouflage surface according to certain rules. Comparing with traditional technology by manual work, the digital camouflage technology has more remarkable effect in response to high altitude reconnaissance. However, the traditional spraying method is still mostly applied, which can't adapt to current requirement in either spraying effect or spraying efficiency. For this reason, on the basis of our own rectangular-coordinate spraying robot, it is proposed a fast control algorithm for digital camouflage spraying robot based on a latent color points-of-variability theory. This algorithm enables the robot to control the spraying gun only at the positions of the latent color points of variability. So the spray work can be completed efficiently. Experiments show the effect of our algorithm. This study could supply important references for theory research and project implementation of military digital camouflage technology.
