摘要

详细介绍了二次误差度量法在点云模型简化数据处理中的原理、方法及其应用.针对其存在的局限性,引入加权思想,很好地处理了图形表面模型三角化格局对原方法的影响.通过实验及精度分析表明,算法整体上要比传统二次误差度量法算法的精度高,而且可以保留更多的特征点.%The principles, methods and its application of quadratic error measure in the model to simplify the data processing are described. According to its flaw, a weighted thinking is introduced, well handels with the graphical surface model triangle pattern impacting on the original method. The experiments and precision analysis show that the accuracy of the proposed algorithm is more than traditional one, and could keep more feature points.
