Abstract: Examples describe using a two dimensional floor plan, rather than a three dimensional (3D) reconstruction of a scene, to localize a camera. A floorplan of an environment is accessed and an image of the environment captured by a camera in the environment is received. The image is input to a trained neural network to predict an array of rays from the camera to surfaces in the environment indicated in the floorplan. Using the array of rays it is then possible to compute 3D position and orientation of the camera with respect to the floorplan.

Abstract: A training system trains a floor plan-encoding machine-trained model (“model”) that converts an image that depicts a floor plan into a universal latent-space floor plan representation. The floor plan representation is referred to as universal or uniform because different floor plans that depict the same building layout in different ways map to the same latent-space floor plan representation. The training system also trains an image-encoding model that maps a camera image that depicts a part of a building layout to a latent-space image representation. A fusing operation integrates the latent-space image representation into a spatially-matching part of a latent-space floor plan representation produced by the floor plan-encoding model. The approach used by the training system eliminates the need to train and maintain different downstream models.
