  • 摘要: 自主航行能力系统性测试、验证与可靠性评价是智能船舶产业化应用的重要前提,为明确不同测试对象对于自主航行测试场景的需求,对自主航行测试场景的测试对象、场景定义、构建方法和测试方式进行梳理。依据测试对象和场景需求的特点,将场景构建方法分为真实数据提取、机理建模重构、数据驱动衍生和优化搜索采样方法,对比阐述不同场景构建方法的性能和所生成场景的特点,并结合算法验证优化、性能评估和安全验证等不同测试需求分析场景构建方法所存在的问题。研究结果表明:实际应用要求测试场景构建技术充分关注测试场景结构体系的完备描述、场景组合爆炸和场景系统动力学演化问题。未来的研究应重点关注异质交通场景发展趋势,丰富智能船舶测试理论和方法体系,为智能船舶的研究成果产业化应用奠定理论与技术基础。

     

    Abstract: Systematic testing, verification and reliability evaluation of autonomous navigation capability are important prerequisites for the industrial application of intelligent ships. To clarify the requirements of different test objects for autonomous navigation test scenarios, the test object, scenario definition, construction method and testing approach of autonomous navigation test scenarios are sorted out. Based on the characteristics in test object and scenario requirements, the scenario construction methods are divided into real data extraction, mechanism modeling and reconstruction, data-driven derivation, and optimization search methods. The performance and characteristics of different scenario construction methods are compared and described, and the problems of scenario construction methods are analyzed in combination with different testing requirements such as algorithm verification optimization, performance evaluation, and safety verification. Research results show that the scenario construction technology for practical applications should fully consider the complete description of the test scenario structure system, scenario combination explosion, and scenario system dynamics evolution. Future research should focus on the development trend of heterogeneous traffic scenarios, enrich the theoretical and methodological system for testing intelligent ships, and lay a theoretical and technical foundation for the industrial application of research results on intelligent ships.
