Problems solved by technology

In the actual production process, the efficiency is low, and there is often a certain deviation between the color ratio and the actual standard requirements. At the same time, in order to improve the design efficiency and ensure the color ratio, the same batch of products often only fine-tune the product pattern, which is difficult to meet the digital camouflage product pattern. Diverse Design Requirements

Embodiment

[0057] like figure 1 , in an automatic generation algorithm of digital camouflage CAD patterns for shelters and special vehicles, first obtain the CAD model of the shelter or special vehicle to be sprayed, firstly extract the outline boundary of the shelter and the CAD drawing of the special vehicle through CAD secondary development, and Obtain the extremum (Xmax, Xmin) and (Ymax, Ymin) of the coordinates of the model in the two directions of XY; generate a rectangular area of ​​[Xmax-Xmin, Ymax-Ymin] size on the shelter and special vehicle CAD pattern, and Generate a grid pattern at an interval of 10cm in both XY directions, such as figure 2 As shown, a total of [Xmax-Xmin] / 10* [Ymax-Ymin]*10 cells are generated, and then each smallest cell is traversed along the XY direction in turn, and the three attributes of each color block are sequentially stored in the algorithm ( int x, int y, bool n). Namely: X, Y direction coordinate value, whether it can be filled. Among them, ...

Abstract

The invention provides a digital camouflage CAD pattern automatic generation method for a shelter and a special vehicle. The method comprises the following steps: digitally coding a to-be-sprayed CAD pattern and a camouflage pattern in a digital camouflage library; selecting the most suitable spraying color in real time in the digital camouflage color filling process according to a greedy selection algorithm of the filling color; and finally, calculating the manual intervention factor of each digital camouflage pattern in the camouflage library in real time, and randomly selecting the camouflage pattern according to the manual intervention factor, thereby realizing rapid and random selection and filling of the digital camouflage pattern. Finally, generating the digital camouflage patterns of the square cabin and the special vehicle quickly and automatically, shortening the digital camouflage design time, and improving the pattern design diversity and accuracy.

Description

technical field [0001] The invention relates to the field of automatic generation of digital camouflage patterns, in particular to a method for automatically generating digital camouflage CAD patterns for shelters and special vehicles. Background technique [0002] Digital camouflage is a new type of camouflage pattern composed of "pixels". This new type of pattern uses the principle of visual psychology, can adapt to the concealment needs in various environmental backgrounds, and has obvious advantages in concealment. As the demand for stealth in military shelters and special vehicle equipment continues to increase, the proportion of shelters and special vehicle products that require digital camouflage spraying continues to increase. The design of digital camouflage patterns for traditional square cabin special vehicles relies on manual division of grids in CAD software for square cabins and plan views of special vehicles, and then drags the grid patterns in the template l...
