Nested target identification method and device

The invention relates to a nested target identification method and device, and the method comprises a data labeling step: carrying out the complete contour labeling of each target nested in a sample image through employing different colors or the same color but different serial numbers. Through the method or the device, the identification of the nested or capping target can be realized, a plurality of targets with a nested or capping relation are identified as corresponding target semantics respectively, an accurate semantic segmentation result is restored, and the problem that a traditional method cannot accurately identify the nested target is solved. 本发明涉及一种嵌套目标的识别方法及装置，该方法包括数据标注步骤，在所述数据标注步骤中，对于样本图片中嵌套的各个目标，分别用不同颜色或者相同颜色但不同序号进行完整轮廓标注。通过本方法或装置可以实现嵌套或者压盖目标的识别，将存在嵌套或者压盖关系的多个目标分别识别为对应的目标语义，还原准确的语义分割结果，改善传统方法无法准确识别嵌套目标的问题。
