FlightBench: Benchmarking Learning-based Methods for Ego-vision-based Quadrotors Navigation
<|reference_start|>FlightBench: Benchmarking Learning-based Methods for Ego-vision-based Quadrotors Navigation: Ego-vision-based navigation in cluttered environments is crucial for mobile systems, particularly agile quadrotors. While learning-based methods have shown promise recently, head-to-head comparisons with cutting-edge optimization-based approaches are scarce, leaving open the question of where and to what extent they truly excel. In this paper, we introduce FlightBench, the first comprehensive benchmark that implements various learning-based methods for ego-vision-based navigation and evaluates them against mainstream optimization-based baselines using a broad set of performance metrics. Additionally, we develop a suite of criteria to assess scenario difficulty and design test cases that span different levels of difficulty based on these criteria. Our results show that while learning-based methods excel in high-speed flight and faster inference, they struggle with challenging scenarios like sharp corners or view occlusion. Analytical experiments validate the correlation between our difficulty criteria and flight performance. We hope this benchmark and these criteria will drive future advancements in learning-based navigation for ego-vision quadrotors.
