Covisibility Matching 重建失败

[Oreki718]

大佬好，我在我自己的数据上尝试按照指示的方式进行基于 covisibility matching 的重建，结果显示重建失败。retrieval 文件已经按照 https://github.com/openxrlab/xrlocalization/blob/main/docs/en/tutorials/generate_image_pairs.md 进行了生成，并且在 retireval matching 成功生成了正确的重建效果。camera_colmap 由colmap重建校准生成，在 sequence 和 retrieval 下验证可用。

Debug了一下，发现covisibility matching 导出的 frame_pairs 数量为0
