复杂环境下玻璃绝缘子自爆的实时检测方法

Dianci bileiqi
针对无人机巡检电力玻璃绝缘子过程中，无人机的计算能力和存储资源有限，且在黑暗、光照、噪声干扰、特殊天气等复杂环境下拍摄的玻璃绝缘子自爆缺陷图片难以检测的问题。提出一种适用于复杂环境下玻璃绝缘子自爆的实时检测方法。该方法以具有轻量化特点的YOLOX-s目标检测模型为基础。首先，采用多阶段迁移学习策略提升模型整体性能。其次，通过新增一层浅层特征进行特征融合，使得融合后特征的位置信息更加丰富，更利于自爆缺陷小目标的定位。同时利用Focal Loss专注困难样本学习，提高模型在复杂环境下的鲁棒性。最后 ...

一种将柔性薄膜材料粘附在玻璃基底上的方法

 本发明公开了一种将柔性薄膜材料粘附在玻璃基底上的方法,该方法包括：步骤1：清洗玻璃基底和柔性薄膜材料；步骤2：在该玻璃基底上滴加SU8光刻胶；步骤3：将该柔性薄膜材料的一侧接触该SU8光刻胶,并将该柔性薄膜材料从一侧到另外一侧赶平；步骤4：用一个平整面挤压该柔性薄膜材料,赶出多余的SU8光刻胶,并用丙酮擦除多余的SU8光刻胶；步骤5：用紫外光从玻璃基底背面曝光；步骤6：清洗并烘干。利用本发明,解决了在柔性薄膜材料表面进行微电子工艺加工的过程中 ...
