An attempt to generate new bridge types from latent space of variational autoencoder
We try to generate new bridge types using generative artificial intelligence technology.The grayscale images of the bridge facade with the change of component width were rendered by 3ds MAX animation software,and then the OpenCV module performed an appropriate amount of geometric transformation(rotation,horizontal scale,vertical scale)to obtain the image dataset of the three-span beam bridge,arch bridge,cable-stayed bridge,and suspension bridge.Based on Python programming language,TensorFlow,and Keras deep learning platform framework,a variational autoencoder was constructed and trained,and low-dimensional bridge-type latent space that is convenient for vector operations was obtained.Variational autoencoder can combine two bridge types based on the original human into one that is a new bridge-type.Generative artificial intelligence technology can assist bridge designers in bridge-type innovation and can be used as the copilot.
