A new kind of moire fringe projector controlled by computer is used for changing the spacial frequency to adapt the contour of the object to be measured.
它采用了一种可由计算机控制的、可变空间频率的莫尔条纹投影仪，利用不同空频的两次变精度测量，以适应待测物体形面的突然起伏。
The HVS function, HVS function is inversely Fourier transformed in frequency domain, and the method is realized by calculating some value of the function in spacial domain as convolve nucleus.
根据HVS函数的特点，对频域中HVS函数进行反傅立叶变换，将空间域中该函数的部分函数值作为特定的模板参数，并与原图像进行卷积来实现边缘检测。
