B-spline Surface in Reverse Engineering of Body Model

Sun Zao-you

Abstract

B-spline surface was used in the body modeling of reverse engineering,quadrilateral surface model that can be recognized by CAD was constructed,and sequence and smoothly merged surface was realized.As a study case,the body surface of the car was protracted by this technique.It is significant in improving the precision of NC machining for free surface of motor vehicles.
