Sony patents method to auto-calibrate moving markers in 3D spaces
Sony describes a system that automatically updates the location data for markers attached to moving objects. It uses a camera to track both fixed and moving markers, then adjusts the digital map of the moving parts to match the real world.
In the filing’s own words
To greatly improve calibration efficiency of a movable marker arranged on a movable rigid body. Provided is an information processing device including: a processing unit that rewrites second map data including position information of a plurality of movable markers arranged on a movable rigid body, on the basis of a first position and orientation related to a camera, the first position and orientation being estimated on the basis of an image captured by the camera and first map data including position information of a plurality of fixed markers arranged on a non-movable body, and a second position and orientation related to the camera, the second position and orientation being estimated on the basis of the image and the second map data.
What exactly they claim (claim 1)
1. An information processing device comprising: a processing unit that rewrites second map data including position information of a plurality of movable markers arranged on a movable rigid body, on a basis of a first position and orientation related to a camera, the first position and orientation being estimated on a basis of an image captured by the camera and first map data including position information of a plurality of fixed markers arranged on a non-movable body, and a second position and orientation related to the camera, the second position and orientation being estimated on a basis of the image and the second map data.
