A new sub-pixel algorithm based on the principle of the parabola fitting is proposed.
导出了分段抛物线插值拟合公式，并对经验公式和抛物线拟合公式均以iso为基准进行了误差评估。
Also, the fitting formula of piecewise parabola interpolation is derived. The error evaluation based on ISO is accomplished for both experiential formula and parabola fitting formula.
当然，你还是要找到最佳的，这里指对数据点，拟合度最高的抛物线。
And, of course, you are trying to find somehow the best. That would mean here fitting the best parabola for your data points.
文中指出，以往的一些研究者对数据采用线性拟合，只适用于特定的地区，特定的层位，而抛物线公式可以具有普遍的适应性。
It is pointed out that some researchers 'linear fitting of velocity data is only applied to a particular area or a particular formation while the parabola formulas have wide adaptability.
