Cascade target recognition method and system based on deep learning

The invention provides a cascade target recognition method and system based on deep learning, and the method comprises the steps: obtaining a to-be-detected sample of an inspection image, marking a target detection sample, and expanding the number of samples; fusing multiple features of the image enhancement data to carry out a multi-stage deep learning detection algorithm, realizing significant equipment detection for a target with a large proportion, and eliminating noise interference of a complex background on the detection algorithm. Multi-stage deep learning algorithm detection is carriedout by fusing multiple features of image enhancement data, so that the detection accuracy of deep learning in small target detection is improved, and the influence of image quality on the detection algorithm is reduced. 本公开提供了基于深度学习的级联目标识别方法及系统，获取巡检图像的待检测样本，对目标检测样本标记，并对样本数量进行扩充；融合图像增强数据的多特征进行多级深度学习检测算法，实现针对占比较大目标的显著设备检测，剔除复杂背景对检测算法的噪声干扰；融合图像增强数据的多特征进行多级深度学习算法检测，提高深度学习在小目标检测中的检测准确率，降低了图像质量对检测算法的影响。
