This paper aims to construct a display facility design method based on image recombination to provide a reference for related design. First of all, through the analysis of the role of different images in the design process, To classify the images, Clear up the transformation process of different images in the design process. Then, according to the theory of biological DNA recombination, the image recombination method model and the design method model based on image recombination are constructed from the homologous and non-homologous image dimensions, and the method and application process of image recombination are explained. Finally, an example is given to illustrate the operation of the method. The results show that the method has good operability and can improve the design effect. through the analysis of different image output in the design process, the homologous image provides initial prototype design inspiration, homologous image provides reference and guidance of design expression means, the two together to make more confusing concept gradually, realization to provide direction for design goal, this method can effectively improve the effect of the design.
