  1. 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

    本文採用投影光棚相位法和數字卷積濾波技術:根據柵線的條紋灰度值分佈具有極大極小分佈的特性,提出卷積濾波形貌光學自動檢測的圖像處理方法,有效地實現了頻譜自動移位,從而進一步提高了圖像處理的速度和形貌測量技術的自動化程度;同時對採用兩光學主軸相交,且非遠心投影系統所產生的誤差進行了分析,並提出了修正方法。
