摘要
雹云识别是一个多参数的模式识别问题, 应用物元可拓思想将单参数雹云识别的不相容性转化为相容性问题。在与成都地区雹云识别的物元可拓模型进行对比后, 根据低纬高原地形及气候特点, 通过适当增加参数, 构造完成低纬高原雹云识别的物元可拓模型, 以此进行雹云识别, 准确率达86%以上。
Hail cloud recognition is a pattern recognition problem of multi-parameter. The recognition result of hail cloud based on single parameter is always non-compatible. The basic thinking of matter elements and extension set was used for changing the non-compatible problem into compatible problem. After the contrast between it and Chengdu region hail cloud recognition, according to the low latitude plateau terrain and the climate characteristic, and through the suitable increasing parameter, the recognition model of hail cloud on low latitude plateau is completed. The accuracy of hail cloud recognition by this method is over 86%.
