Research on generation method of intelligent navigation test scenarios for ships

基于场景的虚拟测试技术对船舶智能化、自主化发展起着关键作用,相比于真实航行测试成本高、危险系数大、可重复性差等缺陷,它的试验场景配置灵活,效率高,可重复性强,安全性高,成本低,能够为船舶的自主化、智能化提供必要的技术支持。面向船舶虚拟测试场景生成领域,梳理国内外场景研究现状,明确船舶虚拟测试场景定义,解析测试场景关键要素,构建虚拟测试场景基本架构;根据船舶测试要素的来源对测试场景要素进行划分,阐述一系列场景生成关键技术。最后根据采集数据进行特征提取,提出一种船舶智能航行场景生成方法。该方法使得虚拟测试变得更加安全、高效、覆盖面更广,是一种可靠的船舶场景生成方法。

Virtual test based on scenario plays a key role in the development of ship intelligence and autonomy.Com-pared with the defects of navigation test,such as high cost,high risk factor and low repeatability,its test scenario configura-tion is flexible,high efficiency,strong repeatability,high safety,and low cost,which can provide necessary technical sup-port for ship autonomy and intelligence.For the field of ship virtual test scene generation,the research status at home and abroad is reported,the definition of ship virtual test scene is defined,the key elements of test scene are analyzed,and the ba-sic framework of virtual test scene is constructed.According to the source of ship test elements,the test scene elements are divided.Expounding a series of key technologies for scene generation,and finally feature extraction is carried out according to the collected data and proposing a method for generating intelligent ship navigation scenes.This method makes virtual testing safer,more efficient,and has wider coverage.It is a reliable method of Ship scene generation.
