摘要
提出了一种基于方向可调小波变换的二次多项式插值图像亚像素边缘定位的方法,不仅计算量小,其定位精度可以达到亚像素级,且具有较好的抗噪性能在机械零件尺寸测量中有很高的应用价值。
this paper presents a adjustable wavelet transform based on direction of quadratic polynomial interpolation image of subpixel edge detection method, not only a small amount of calculation, the positioning accuracy can reach sub-pixel level, and has better performance of noise in the measurement of mechanical parts size has a high application value.
