Asynchronous dynamic vision sensor led ai tracking system and method

A tracking system, comprising

• a processor;
• a dynamic vision sensor (DVS) operably coupled to the processor, the DVS having an array of light-sensitive elements in a known configuration, wherein the dynamic vision sensor is configured to output signals corresponding to two or more events at two or more corresponding light-sensitive elements in the array in response to changes in light output from two or more light sources in a known configuration with respect to each other and with respect to a controller body, wherein the output signals include information corresponding to times of the two or more events and locations of the two or more corresponding light-sensitive elements in the array,
• wherein the processor is configured to determine an association between each of the two or more events and two or more corresponding particular light sources of the two or more light sources and fit a position and orientation of at least the controller using the determined association, the known configuration of the two or more light sources with respect to each other and with respect to the controller body and the locations of the one or more corresponding light-sensitive elements in the array.

A method for tracking comprising:

• detecting two or more events corresponding to changes in light output from two or more light sources with a dynamic vision system (DVS) having an array of light-sensitive elements in a known configuration
• determining an association between each of the two or more events and two or more corresponding light sources wherein the two or more light sources have a known configuration with respect to each other and with respect to a controller body;
• fitting a position and orientation of at least the controller using the determined association, the known configuration of the two or more light sources with respect to each other and with respect to the controller body and the locations of the one or more corresponding light-sensitive elements in the array.
