人工智慧自走車

open access: yes, 2022
[[abstract]]人工智慧 (Artificial Intelligence,AI) 是現在非常火熱的技術,影像辨識、語音辨識都因為加入了AI而得到大幅度的進步。現在的AI是使用機器學習的方式,以神經網路為架構,只要提供夠多的樣本,再讓它經過反覆的訓練來向己找出解答,且不需要工程師的介入,它就能完成你要它執行的動作。 本專題採用App Inventor 團隊所發表 AI 影像辨識套件Personal Image Classifier (自訂影像分類器)作為人工智慧神經網路的訓練平台。以App ...

ToF相机的有效深度数据提取与校正算法研究

open access: yes智能科学与技术学报, 2020
提出一种针对 ToF 相机的有效深度数据提取与校正算法,利用深度图和置信度图对深度信息进行校正。首先,基于核密度估计和连通域标记对测得的深度图进行自适应分割;然后使用一种改进的结构张量进行边缘检测,从而探测深度图中的无效像素和飞行像素;最后用双三次方插值或投票操作纠正或剔除这些像素,同时使用增强置信度剔除错误像素。实验结果证明了该算法的有效性,对比传统方法,本文所提算法可以剔除更多的无效像素,且保留更多的有效深度数据,对于噪声的鲁棒性也更好。

太阳活动区EUV图像的生成式模型耀斑分级与预报

open access: yesKongjian kexue xuebao, 2023
近年来,不断发射的空基观测台持续传送回海量日面图像及日地间气象数据,为采用人工智能技术对太阳活动进行预报预警提供了数据基础。但是,极端天气爆发少,样本量较少;中等程度爆发稍多,样本量较多;常规无爆发天气常见,样本较为集中,样本不均衡状况严重影响机器学习方法在空间天气领域的广泛应用。本文面向多源多通道多尺度日面图像信息,构建了来自SOHO和SDO的1996-2015年日面活动区图像数据集;针对数据分布的不平衡,对太阳活动区图像作耀斑分级与预报。在对比分析元学习算法的基础上 ...
