USING CLOUD COMPUTING TO IMPROVE ACCURACY OF POSE TRACKING

Disclosed is a system (100, 200) comprising server (102, 202, 308) and data repository (104, 204, 310) storing three-dimensional (3D) environment model, wherein server is configured to: receive, from client device (106, 206, 300), first image(s) of real-world environment captured by camera(s) (108, 208, 302) of client device, along with information indicative of first measured pose of client device measured by pose-tracking means (110, 210, 304) of client device; utilise 3D environment model to generate first reconstructed image(s) from perspective of first measured pose; determine first spatial transformation indicative of difference in first measured pose and first actual pose of client device; calculate first actual pose, based on first measured pose and first spatial transformation; and send information indicative of at least one of: first actual pose, first spatial transformation, to client device for enabling client device to calculate subsequent actual poses.
