摘要
提出了一种利用计算机视觉技术和模式识别解决指针式仪表判读的方法。由摄像头获取仪表盘图像,将其转换成数字信号,再利用相关的图像处理方法对表盘图像进行中值滤波、图像的增强和锐化、二值化处理,然后根据Hough变换提取目标信息,确定出指针式仪表的读数。经实验结果表明,该算法具有较高的精度。
This paper proposes a kind of method which adopts computer vision technology and pattern recognition to solve indexinstrument measuring means. The gauge board image is gained from CCD and transformed into digital signal, and it uses the related image processing method to media filter and image enhance and sharp,then adopt Hough transformation to extract object information,ascertain reading of index-instrument. The experiment result proves that the operator has higher precision.
