3D Gaussian Splatting from Unposed Spike Stream

ing upon this foundation, we devise a progressive optimization framework to facilitate swift 3D reconstruction. The experimental results demonstrate that our method achieves up to 7.4dB higher PSNR and 40% lower Absolute Trajectory Error (ATE) compared to state-of-the-art methods under challenging high-speed scenarios while maintaining the fastest reconstruction speed among spike-based methods.
