FastViDAR: Real-Time Omnidirectional Depth Estimation Via Alternative Hierarchical Attention

In this paper, we propose FastViDAR, a novel framework that takes four fisheye camera inputs and produces a full 360 depth map along with per-camera depth, fusion depth, and confidence estimates. Our main contributions are: (1) We introduce Alternative Hierarchical Attention (AHA) mechanism that eff…
