Abstract :
[en] Environmental perception is a key element of autonomous driving because the information received from the perception module influences core driving decisions. An outstanding challenge in real-time perception for autonomous driving lies in finding the best trade-off between detection quality and latency. Major constraints on both computation and power must be taken into account for real-time perception in autonomous vehicles. Larger detection models tend to produce the best results but are also slower at runtime. Since the most accurate detectors may not run in real-time locally, we investigate the possibility of offloading computation to edge and cloud platforms, which are less resource-constrained. We create a synthetic dataset to train object detection models and evaluate different offloading strategies. We measure inference and processing times for object detection on real hardware, and we rely on a network simulation framework to estimate data transmission latency. Our study compares different trade-offs between prediction quality and end-to-end delay. Following the existing literature, we aim to perform object detection at a rate of 20Hz. Since sending raw frames over the network implies additional transmission delays, we also explore the use of JPEG and H.265 compression at varying qualities and measure their impact on prediction. We show that models with adequate compression can be run in real-time on the edge/cloud while outperforming local detection performance.
