Abstract
Streaming perception is a task of reporting the current state of autonomous driving, which coherently considers the latency and accuracy of autopilot systems. However, the existing streaming perception only uses the current and adjacent two frames as input for learning the movement patterns, which cannot model actual complex scenes, resulting in failed detection results. To solve this problem, we propose an end-to-end dual-path network dubbed LongShortNet, which captures long-term temporal motion and calibrates it with short-term spatial semantics for real-time perception. Moreover, we investigate a Long-Short Fusion Module (LSFM) to explore spatiotemporal feature fusion, which is the first work to extend long-term temporal in streaming perception. We evaluate the proposed LongShortNet and compare it with existing methods on the benchmark dataset Argoverse-HD. The results demonstrate that the proposed LongShortNet outperforms the other state-of-the-art methods with almost no extra computational cost.
