Cloud-Based Camera Calibration

Server system for processing image data from a camera in a physical space for rendering a virtual object in a 3D virtual environment, the virtual object representing an object in the physical space,

• the camera having a camera pose in the physical space and the second device having a second pose in the physical space, the second pose being different from the camera pose;
• the server system arranged to communicate via a network to a processor system,
• wherein the server system comprises
• a network interface for exchanging data via the network and
• a processing resource configured to:
• receive image data of the physical space obtained by the camera, second data of a second device in the physical space and a calibration command from the processor system via the network interface;
• process the image data and the second data according to the calibration command to generate calibration data indicative of the camera pose and the second pose;
• and
• send the calibration data to the processor system via the network interface.
