By this, we can obtain the space information, however, because of the body sharp and reflex characters are more complicated, and the traditional way which used for detecting the center of structured light have some weakness. So the accuracy of structured light methods hinges on the ability to locate the "center" of the 3D information. New method presented in this paper starts by convolving a given image with masks in a selected number of directions.

但是由于物体表面形状、反射特性比较复杂，而传统的确定结构光条纹中心位置的方法极值法、门限法、重心法、高斯拟合法等都存在不足，这就使得结构光条纹中心位置的准确检测成为影响三维信息获取精度的关键问题之一。
