Abstract

Embodiments that relate to presenting a textured shared world model of a physical environment are disclosed. One embodiment includes receiving geo-located crowd-sourced structural data items of the physical environment. The structural data items are stitched together to generate a 3D spatial shared world model. Geo-located crowd-sourced texture data items are also received and include time-stamped images or video. User input of a temporal filter parameter is used to temporally filter the texture data items. The temporally-filtered texture data items are applied to surfaces of the 3D spatial shared world model to generate a textured shared world model of the physical environment. The textured shared world model is then provided for display by a display device.
