摘要
提出一种在识别后期采用修正的无零级条纹调节联合变换相关代替传统联合变换相关(CJTC)的新的识别方法。此方法在原基础上对功率谱作了一系列修正。理论分析、计算机模拟实验和对实物模型的识别实验结果都表明该方法不仅具有本征三维识别的特点,而且相对于CJTC而言其能够抑制相关面上的中央零级项,很大程度上锐化了一级相关峰,明显地提高了信噪比和识别力。该方法进一步拓宽了三维物体识别的应用前景。
A new method that replaces conventional joint transform correlator（CJTC） with modified non-zero fringe-adjusted JTC on the back recognition was proposed. The method modified the joint power spectrum. Both theoretical analysis and computer simulation results show that the method has the character istic of 3D object recognition, eliminates the central zeroorder component, sharpens the correlation peak, and increases the SNR and ability of correlation recognition（ACR）. Our method will widen the application foreground of 3D object recognition
