摘　　要：介绍了利用二位图像处理方法对缓冲器进行实时处理的自由高度自动检测仪,硬件采用单片机和PLD就可以实现,大大降低了系统的成本。系统可以自动检测、调整CCD的感受光强,保证系统获取有效的图像信号。采用双标准试件自整定长度的输出—输入特性,保证了系统的测量精度。系统采用了筛选计量采样图像的方法,排除了测量基准参考点选择不当的测量误差。The paper introduces the free height autoanalyzer, which can process the bumper using the method of image proceeds.The hardware uses the singlechip and PLD to lower the cost of system consumedly. Moreover, the system can check and adjure the intersity of light to guarantee that the system obtains the valid signal. Using the output and input characteristics when system measures the length of the tested objects with two - standant, the instrument can guarantee the test precision of system. Using the sieving to calculate the samples of image, the system can remove the error when cheeses the unapt basic testing reference.
