4DSloMo: 4D Reconstruction for High Speed Scene with Asynchronous Capture
Researchers have developed a novel system called 4DSloMo for reconstructing high-speed dynamic scenes using standard, low-frame-rate cameras. The system employs an asynchronous capture scheme, staggering camera start times to achieve an effective frame rate of 100-200 FPS without specialized hardware. Additionally, a video-diffusion-based generative model is used to fix artifacts arising from sparse-view reconstruction due to the asynchronous capture, thereby enhancing detail and temporal consistency.
