基于光栅调制的归一化频谱三维识别

为了解决三维物体识别速度和识别能力问题,提出了一种采用光栅调制基频滤波的归一化频谱相关识别新方法。基于归一化频谱相关模型,对物体平移和旋转后的基频模进行了理论分析和实验论证,得出了物体基频模具有平移不变性的特性。实验论证了该方法的有效性,采用该方法不仅能有效识别三维位物体,而且还能估计物体的旋转角度,精度优于±2°。结果表明,由于该方法只需投影一幅正弦光栅条纹,采集一帧变形条纹图,可以适用于三维物体的动态识别和在线识别。

Three-dimension recognition of normalized spatial spectrum based on grating modulation

A new normalized first-order spatial amplitude spectrum three-dimension(3-D) recognition method based on grating modulation was presented to speed up and improve ability for 3-D recognition.The theoretical model was established in detail,the properties of rotation and shift were theoretically and practically analyzed to conclude its shift invariant speciality.Experiments showed its flexibility.It can not only recognize 3-D object efficaciously,but also estimate the rotated angle of the 3-D object with highe...
