Claim 0:
1. A method of generating a ground truth output dataset using an electronic eyewear device comprising a processor, a camera, and an inertial measurement unit, the method comprising steps of:
recording a primary reference set using the electronic eyewear device in motion traversing a path through a physical environment, wherein the primary reference set comprises a series of real images captured by the camera and a series of real motion data captured by the inertial measurement unit;
calculating, by the processor, a headset trajectory based on the primary reference set;
generating, by the processor, a continuous time trajectory function for interpolating the headset trajectory relative to the series of real motion data; and
generating, by the processor, an output dataset associated with a simulated sensor configuration and in accordance with the continuous time trajectory function, wherein the simulated sensor configuration comprises one or more simulated cameras and one or more simulated inertial measurement unit sensors, such that the output dataset represents the simulated sensor configuration in motion along a virtual path through a first virtual environment.
