[目的]为实现果园自然场景下智能农业机器人对桃花的准确、快速、有效检测.[方法]文章采用相机获取桃花图片数据,通过LabelImg软件进行人工标记建立桃花目标识别的检测样本数据集,训练Darknet深度学习框架下的YOLO v4模型对桃花进行识别.[结果]模型精度评估表明,YOLO v4模型的平均准确率MAP值(86%)比Faster R-CNN的MAP值(51%)高出35%.[结论]YOLO v4与经典的算法相比,对各种自然环境下的桃花检测具有较好的实时性和鲁棒性,可为精准识别桃花提供重要参考价值,桃花精准识别为疏花疏果作业奠定了基础.

由于制造工艺和器件老化等原因,不同IGBT模块之间的阈值电压会存在一定差异,并对动态不均流产生很大影响.针对此问题,首先分析了阈值电压差异对并联均流的影响机理;然后建立了阈值电压差异与开通延迟时间之间的量化关系;最后以大功率IGBT模块并联为测试对象,通过对驱动延迟时间进行补偿的方法进行双脉冲测试,验证该方法的有效性.结果表明,该方法最大可以将不均流度从14.04%降低到2.21%.
