Abstract

本发明公开了一种无监督多视图立体匹配方法,包括:对参考视图应用超像素分割,得到表征物体边界的分割图,将分割图进行数值缩放到预设范围,生成基础深度图;将参考视图的每个像素所对应的像素坐标进行记录以形成一个坐标图,将坐标图数值缩放到预设范围,生成一随图像坐标连续变化的偏置深度图;将基础深度图和偏置深度图相加,得到伪深度图;基于伪深度图将参考视图变形为伪源视图,并将参考视图和伪源视图输入多视图立体匹配网络,得到预测深度图,以构建伪深度监督;基于多视图样本采用数据增强获得强增强的样本和弱增强的样本,并分别送入到与多视图立体匹配网络具有完全相同结构的网络中,分别得到两个不同的预测结果,以构建一致性约束;以无监督的方式训练多视图立体匹配网络。
