convolution filtering meaning in English

褶积滤波

The algorithm , basing on convolution filtering technique and the fringes " gray values max - min distribution , can automatically and accurately carry out space frequency spectra shifting without spectra analysis and spectrogram in the technique of phase method of projected grating for 3 - d object shapes measurement . the new algorithm makes image processing much caster and the technique of object shapes measurement more automated . the phase error caused by filtering and the crossed - optical - axes geometry setup is also discussed
本文采用投影光棚相位法和数字卷积滤波技术：根据栅线的条纹灰度值分布具有极大极小分布的特性，提出卷积滤波形貌光学自动检测的图像处理方法，有效地实现了频谱自动移位，从而进一步提高了图像处理的速度和形貌测量技术的自动化程度；同时对采用两光学主轴相交，且非远心投影系统所产生的误差进行了分析，并提出了修正方法。
