Single-sided dashcam footage is now sufficient to reconstruct complete, metric-scale 3D vehicle assets by exploiting bilateral symmetry directly within Gaussian space.

Envision4D transforms future scene extrapolation in autonomous driving, achieving unprecedented accuracy and stability in dynamic environments.

Representing highly nonlinear vehicle dynamics in a lifted linear space via Koopman operator theory enables state-of-the-art long-term state estimation for complex electric trucks.
