According to the need of canopy visualization calculation in the digital plant research, we introduced a method, using Non-Uniform Rational B-Splines (NURBS) interpolation and multi-line segment splitting algorithm, to reconstruct the 3D morphological structure of maize leaf with a complexity controllable mesh. Using the data cloud obtained by digitizer, construct the surface of maize leaf by calculating the knot vectors and reverse calculating surface control points by difference calculation. The final visualization effect is realistic. According to leaf morphological characteristics, leaf surface mesh can be simplified by using inverse calculation of multi-line segment splitting algorithm, and the surface main characteristics can be maintained simultaneously. This method can be used in canopy visualization calculation and light distribution calculation. Results showed that it can improve the calculation efficiency obviously without increase the calculation error.
