应用加权中值滤波法对薄壁梁式挠性器件下摆量进行高准确度CCD检测。薄壁梁式挠性器件在测量过程中测量图像存在高频抖动现象,因此测量准确度不高,运用加权中值滤波后使用最小二乘法细分技术,可以在实现提高测量准确度的同时,消除高频抖动带来的误差,从而可以有效提高CCD测量薄壁梁式挠性器件下摆量的准确度。实验表明,该方法比传统测量方法准确度提高20倍以上。

Applying Weighted Median Filtering Method to Detect the Heaviness of Thin Wall Beam Flexible Devices with High Accuracy. Thin-walled beam-type flexible devices measure the image during the measurement of high-frequency jitter phenomenon, so the measurement accuracy is not high, the use of weighted median filtering method using least-squares subdivision, can improve the measurement accuracy while eliminating the high Frequency jitter caused by the error, which can effectively improve the CCD thin-walled flexible beam device to measure the accuracy of the amount. Experiments show that the accuracy of this method is more than 20 times higher than the traditional method.
