摩托车外覆盖件A级曲面的构建(1)

The Establishment of A-class Curved Surface of Motorcycle Outer Cover Panel(1)

在曲面构建的任何时候都应该检查曲面的准确性、光顺性和连续性,为判断和修改曲面提供依据。此外,当一个模型的曲面构建完成之后,还要进行整体的检查和评价,主要包括特征评价和质量评价两方面。摩托车外覆盖件的曲面构建不是一个简单的拷贝过程,仅仅使曲面模型准确符合测量的点云是远远不够的,A级曲面的品质要求将逐步成为曲面构建的标准。

Whenever a curved surface is established, the accuracy, smoothness and continuity of it should be checked, which serves as the base for judgement and amendment. Besides when the curved surface establishment of a model is completed, further entire check and evaluation are needed, which mainly includes characteristics assessment and quality assessment. The establishment of curved surface of outer cover panel is not simply a copying process and it is not quite enough only to make the curved model conform to he point cloud. The demand for A-class curved surface quality will become the standard for curved surface establishment.
