本论文首先介绍了油罐车加载装置的工作原理,研究了图像定位技术的理论和发展趋势.结合实际的工作环境,提出了油罐车加载装置定位系统的设计方案.根据设计方案,给出了具体的硬件和软件设计.硬件上使用了COMS相机对图像进行捕捉,然后将采集到的数据通过IEEE1394接口传输到FPGA内对系统进行控制,最后通过DSP对采集到的图像进行处理.软件上首先结合整个系统的硬件设计给出了相应的软件设计,然后根据灌口的图像特征,给出了具体的实现算法.算法上本文首先对灌口的数字图像使用邻域平均法进行滤波,去除了图像中的噪声.再采用大律法对图像进行二值化处理,确定出灌口的边沿.然后,根据圆上任意俩条不平行弦的中垂线相交点即为圆心的原理,确定出整个灌口的圆心.最后再根据圆心坐标使用PID算法实现对加载装置位置的定位.

This paper introduces the working principle of tanker loading device to study the theory of image positioning technology and trends.With the actual work environment,is proposed tanker loading unit positioning system design.According to design,given the specific hardware and software design.COMS camera hardware used to capture the image,and then the collected data to the FPGA through the IEEE1394 interface transfer controls within the system,and finally through the DSP for processing the images collected.First,the system software,hardware design combined with the corresponding software design,and then filling the mouth of the image features,given a specific algorithm.This algorithm first irrigation port on the digital image using neighborhood average filtering,removes the image noise.Then using the law of large binary image processing,to determine the edge of the mouth of the filling.Then,according to two articles do not circle any of the strings in parallel vertical point of intersection is the center of the principle,determine the center of the shrub population.Finally,the center coordinates based on PID algorithm using the location of the loading device positioning.
