【摘要】 红外小目标检测系统在军事、国防领域中具有重要的战略应用价值,因此在红外小目标检测系统研发过程中需要对其进行充分的模拟测试来确保其性能。由于数据的敏感性,可公开获取的包含红外小目标的测试图像数据源较少,而大量的测试数据却是研究红外小目标检测算法必不可少的。除此之外,对于红外小目标检测结果的评估也缺乏统一标准,不能满足实时评估分析和应用的需求。针对上述问题,本课题将研制一套针对红外小目标检测系统的测试平台,测试平台能够生成可供红外小目标检测的模拟图像数据源,并具有对检测结果进行评估的功能,还可以实现完整的测试数据发送到检测结果接收的数据交互环路构建。首先,对红外小目标检测系统的测试平台进行功能需求分析,提出具体的设计指标,并制定总体设计方案。之后按照功能需求,将测试平台划分为了两个功能单元,分别为图像生成与仿真控制单元以及图像注入功能单元,并对两个功能单元的硬件平台进行选型设计,在此基础上,针对功能单元现有硬件平台的不足,制作了两个数据传输模块,分别为模拟数据传输模块和反馈传输模块,以实现图像注入功能单元向红外小目标检测系统传递生成的模拟数据,并将检测信息反馈给图像生成与仿真控制单元中对检测结果进行评估分析,以满足整个测试平台数据传输需求。其次,对测试平台中的软件部分进行需求分析与详细设计,并依托了测试平台中的硬件部分,设计了具备功能层和数据流层的模拟图像生成与检测评估软件。其中,功能层为整个软件部分的核心,包含了以云背景为核心的红外模拟图像的生成单元以及对红外小目标检测系统返回的检测结果进行评估的具体实现。数据流层作为整个软件的最底层,包含了接口驱动的控制、数据格式的转换、固件IP的设计与控制等功能。最后,针对设计制作的测试平台进行验证,设计了验证评估的总体方案,并按照方案分别对硬件与软件部分各个功能模块进行测试。测试结果表明该红外小目标检测系统测试平台具备完整的设计功能,满足全部设计指标。更多还原

【Abstract】 The infrared small target detection system has important strategic application value in the military and national defense fields.Therefore,it is necessary to conduct sufficient simulation tests to ensure its performance during the research and development process of the infrared small target detection system.Due to the sensitivity of the data,there are few publicly available test image data sources containing small infrared targets,but a large amount of test data is indispensable for the study of small infrared target detection algorithms.In addition,there is no uniform standard for the evaluation of infrared small target detection results,which cannot meet the needs of real-time evaluation,analysis and application.In response to the above problems,this subject will develop a test platform for the infrared small target detection system.The test platform can generate simulated image data sources for infrared small target detection,and has the function of evaluating the detection results,and can also achieve completeness.The test data is sent to the test result to receive the data exchange loop to construct.First,analyze the functional requirements of the test platform of the infrared small target detection system,put forward specific design indicators,and formulate an overall design plan.Afterwards,according to the functional requirements,the test platform is divided into two functional units,namely the image generation and simulation control unit and the image injection functional unit,and the hardware platform of the two functional units is selected and designed.On this basis,the function is Due to the lack of the existing hardware platform of the unit,two data transmission modules were made,namely an analog data transmission module and a feedback transmission module,to realize the image injection function unit to transfer the generated analog data to the infrared small target detection system and feedback the detection information Evaluate and analyze the detection results in the image generation and simulation control unit to meet the data transmission requirements of the entire test platform.Secondly,the requirements analysis and detailed design of the software part of the test platform are carried out,and relying on the hardware part of the test platform,a simulation image generation and detection evaluation software with a functional layer and a data flow layer is designed.Among them,the functional layer is the core of the entire software part,including the generation unit of the infrared simulation image with the cloud background as the core and the specific implementation of evaluating the detection results returned by the infrared small target detection system.As the bottom layer of the entire software,the data stream layer includes functions such as interface-driven control,data format conversion,and firmware IP design and control.Finally,verifying the designed test platform,designing the overall plan of verification and evaluation,and testing each functional module of the hardware and software parts according to the plan.The test results show that the test platform of the infrared small target detection system has complete design functions and meets all design indicators.更多还原
