Exhaustive Matching:如果你的图像数目相对来说比较少的话(少于几百张),那么选择这个模式可以拥有足够快和足够好的重建效果,在这里,每张图片都和其他的所有图片匹配,block决定了从磁盘中同时读取多少张图片。 Sequential Matching:如果图像是按照一个序列获得的话(比如说一个录影机),这个匹配模式将会很有用,在这种情况下...
这种模式匹配速度足够快并且是最好的效果。每张图片都与其他的所有图片进行匹配。最后生成的块大小取决于你载入内存中的图片的数量。 顺序匹配(Sequential Matching):当你拍照的时候是以连续的方式(比如视频)采集图像的话,这种方式是有用的。连续帧具有视觉重叠。每一帧的图像不必和其他所有图像都进行匹配。只有连续帧...
匹配模式 这里主要介绍一下Colmap中两种常见的匹配模式:sequential和exhaustive。假设输入有 张图,我们要确定图与图之间的关联,一种直接的想法就是两两去计算匹配关系,这就对应了exhaustive模式,而另一种情形是,拍摄时图像是有空间关联的,即相邻拍摄的图像有很大概率是有大重叠的,这时我们就可以只计算相邻的一些图像之...
Sequential Matching: This mode is useful if the images are acquired in sequential order, e.g., by a video camera. In this case, consecutive frames have visual overlap and there is no need to match all image pairs exhaustively. Instead, consecutively captured images are matched against each ot...
Custom Matching:通过 text 文件指定图像的匹配关系,如果是导入的特征可以进一步指定两张图像之间特征的匹配关系。 ''' ## Feature matching 特征匹配 === feat_matching_cmd = colmap_command + " sequential_matcher \ --database_path " + args.source_path + "/distorted/database.db \ --SiftMatching...

Hi What feature matching algorithm is used by the COLMAP sequential matcher? I tried looking at the code but I could not find the name of an algorithm. Is the algorithm documented in a paper or thesis? If so please could you let me know ...
