AR visualisation
raw data (filtering) focus data (mapping) geometric data (rendering) image for AR need to combine raw data with environment
data: geometric data (mesh), camera image, registration data.
challenges with visual coherence: - occlusion - shadows - height in visual field (depth) - relative size - cluttering - geometric alignment, and occlusion
contextual data. with 3d models we can occlude.
some system do online real time 3d reconstruction for occlusion. and also identify and label objects in the scene
ghosting map to show pipes underground. (edges, saliency, texture details, etc)
2.5D is stereo -> 2d image with depth
