SURE通过建模偶然性和epistemic不确定性,联合预测对应关系及其置信度,提升半密集匹配的准确性和效率。

摘要:

建立可靠的图像对应关系对于许多机器人视觉问题至关重要。然而,现有方法在具有大视角变化或纹理缺失区域的挑战性场景中往往表现不佳,其中错误的对应关系仍可能获得高相似度分数。这主要是因为传统模型仅依赖于特征相似性,缺乏明确的机制来估计预测匹配的可靠性,导致过度自信的错误。为了解决这个问题,我们提出了SURE,一种半密集不确定性细化匹配框架,通过建模偶然性和epistemic不确定性,联合预测对应关系及其置信度。我们的方法引入了新的证据头用于可信坐标回归,以及一个轻量级的空间融合模块,该模块以最小的开销增强局部特征精度。我们在多个标准基准上评估了我们的方法,结果在准确性和效率上均优于现有的最先进半密集匹配模型。我们的代码将在https://github.com/LSC-ALAN/SURE上提供。

英文摘要:

Establishing reliable image correspondences is essential for many robotic vision problems. However, existing methods often struggle in challenging scenarios with large viewpoint changes or textureless regions, where incorrect cor- respondences may still receive high similarity scores. This is mainly because conventional models rely solely on fea- ture similarity, lacking an explicit mechanism to estimate the reliability of predicted matches, leading to overconfident errors. To address this issue, we propose SURE, a Semi- dense Uncertainty-REfined matching framework that jointly predicts correspondences and their confidence by modeling both aleatoric and epistemic uncertainties. Our approach in- troduces a novel evidential head for trustworthy coordinate regression, along with a lightweight spatial fusion module that enhances local feature precision with minimal overhead. We evaluated our method on multiple standard benchmarks, where it consistently outperforms existing state-of-the-art semi-dense matching models in both accuracy and efficiency. our code will be available on https://github.com/LSC-ALAN/SURE.
