高空视觉图像识别技术下的信息搜集系统优化设计

Optimization design of information collection system supported by high-altitude visual image recognition technology

当前以信号回波反馈为基础的高空信息搜集系统缺少直观性,反馈的信息也无法得到直观的视觉表达,信息采集过程缺陷明显。为了满足新一代高空信息搜集系统的要求,提出以视觉图像识别技术为基础的高空信息搜集系统设计方法。运用ARM视觉图像传感器采集地面的图像信息,采集后的数据经RTL8019AS以太网控制模块传输,S3C44BOX微处理器模块处理,再由CCD图像搜集模块、解码模块再处理后,数据被发到监控中心进行分析之后存入应用服务器。软件部分采用Visual C++编程系统程序,给出了CCD图像搜集模块以及TCP/IP通信模块内部引入的PLC控制器对高空视觉图像识别下的信息搜集优化设计流程。系统经过测试证明其应用性能良好。

The current high- altitude information collection system based on signal echo feedback lacks of intuition,in which the feedback information can＇t be expressed with intuitive vision,and the process of information collection has obvious defects. To meet the requirements of a new generation high-altitude information collection system,the design method of high-altitude information collection system based on visual image recognition technology is put forward,in which the ARM visual image sensor is adopted to collect the ground image information. The collected data is transmitted by Ethernet control module RTL8019 AS,successively processed by microprocessor processing module S3C44 BOX,CCD image collection module and decoding module,and then sent to the monitoring center for analysis and deposited in the application server. Visual C＋＋ programming system procedure is applied in software. The optimization design process of information collection for high-altitude visual pattern image recognition is provided,in which PLC controlled is introduced in the interior of CCD image collection module and TCP/IP communication module. The test results prove that the application performance of this system is great.
