针对移动报靶训练仪采集图像数据量大和与计算机通信流量大的问题,提出在嵌入式控制器中开辟内部环状内存的方法,以解决DMA传输数据时由于中断延时导致数据丢失的问题。通过图像处理方法对原始数据进行光点检测,将光点数据送给计算机进行后续处理,可以减少网络上的数据流量;结合下采样思想和波门跟踪算法进一步提高光点检测速度。实验证明这些方法能有效解决微型嵌入式控制器处理大型数据流的问题。

For the problem of mobile reported target training instrument that it has huge collected image data and large amount of communication flow with computer,we present a method to set up an internal cyclic memory in embedded controller to solve the problem of image data loss caused by interrupt latency in DMA data transmission.The network traffic can be decreased by detecting the light-spot of original image data using image processing method and then sending the light-spot data to computer for subsequent treatment.Combining the downsampling idea and gate tracking algorithm the light-spot detection speed is further improved.It is proved by the experiment that these methods can effectively solve the problem of micro-embedded controller in dealing with large data flow.
