Pablo Vela shares exo-calib for uncalibrated video tracking

Pablo Vela posted on X that he has long struggled to make person tracking work from synchronized but uncalibrated videos. He stated that tools like vggt left residual error that produced poor results. He said his new version inside rerundotio now accepts time-synced sparse videos and outputs calibrated, gravity-aligned videos within reasonable error. A diagram titled exo-calib shows four input panels of uncalibrated videos with yellow stick-figure people; he explained that blue cameras mark the result after the optimization pipeline. He credits kornia-rs bundle adjustment and says more Gradio spaces are coming.
