@FFmpeg much obliged, really need this for fisheye camera to make shaders in gaussian splatting

@FFmpeg So you don't need to know the marker size?

@FFmpeg Not for the monocular system if we do not need to calibrate the IMU-cam extrinsics

@FFmpeg whats the output? yaml? i want camera matrix, optimized matrix, coefficients and mapx/y.

@FFmpeg Glad to see that people still support Linux operating system, and I hope someone also provides support for Canon scan and print, so I can switch to Linux.

@FFmpeg Awesome tool!

@FFmpeg Awesome!

@FFmpeg now *this* is useful 🤘 what's the next step with this camera? how is the calibrated camera used???

This particular IMU-cam system is used in our internal VIO and VPS test data collection and demonstrations (similar to this one )
