植物冠层光辐射分布的快速深度缓存算法

Fast Z-buffer Algorithm of Solar Radiation Distribution in Plant Canopy

针对植物冠层内光分布计算过程中存在的计算复杂度大、耗时长等问题,提出一种快速深度缓存算法。采用动态选取光照投影平面和确定光照分布密度等方法,设计一套快速计算植物冠层光分布的模拟系统。应用该系统模拟水稻孕穗期冠层内的光分布情况,结果表明,该方法在保持原有算法精度的同时,能缩短计算时间。

The distribution of solar radiation is an important factor to the grouth of plant.In order to reduce the complexity and time-consuming in modeling the distribution of radiation in canopy,this paper aims to improve this model by changing the projection plane and making certain of the density of solar radiation.It uses a software based on advance to model the a boot stage paddy rice to evaluate the improvement,and results show that the advance model can provide the accuracy and reduce the complexity.
