The invention relates to a parachute opening fault judgment method and device and a recovery drop point judgment method. The acquired data set is enhanced to obtain an enhanced data set, and the generalization ability and robustness of the training model during training can be improved by adopting the enhanced data set; marking the data set by adopting a threshold setting method to obtain a labeled data set which comprises a first parachute image and a second parachute image; by reconstructing the parachute opening area of the second parachute image and correcting the actual projection area, the actual parachute opening area can be obtained more accurately, and the accuracy of model training is improved; in the model construction stage, a lightweight fault discrimination model is adopted, the hardware requirement is reduced while the accuracy and the operation efficiency are considered, and the method has the characteristics of lightweight portability and is easier to deploy in a small spacecraft recovery project.
本申请涉及一种降落伞开伞故障判别方法及装置、回收落点判断方法。通过对获取到的数据集进行增强处理得到增强数据集,采用增强数据集能够提高训练模型训练时的泛化能力和鲁棒性;采用阈值设定的方法标记数据集,得到有标签数据集,有标签数据集包括第一降落伞图像和第二降落伞图像;通过对第二降落伞图像的开伞面积进行重构,修正实际投影面积,可以更为准确的得到降落伞实际张开面积,提高模型训练的准确性;在构建模型阶段,采用的是轻量级的故障判别模型,在兼顾准确性与运算效率的同时,降低硬件需求,具有轻量级可移植的特点,更易部署在小型航天器回收项目中。
