摘　　要：该检测系统采用影像传感器获取圆形机械零件的图像信号,利用现场可编程门阵列(FPGA)提取边缘信号,并通过DSP采用改进Hough变换算法对其进行处理和识别,分析零件质量,以提高测量的精度和效率。The system adopts the image sensor to obtain the graphic signals of circular machinery parts. The edge signals are first detected by FPGA (field programmable gate array),the processed and recognized by the DSP (digital signal processor),using improved Hough transform. The DSP calculates the radius and analyses the quality of the machinery parts through the edge signals. Hence, the accuracy and efficiency of the measurement are improved.
