Python 3.x 如何在visualSFM管道中使用openCV中计算的自己的功能

我尝试从多个图像进行三维重建。我目前正在使用visual SFM管道，它将Lowe-SIFT特性作为.feat和.mat格式。两者都是二进制的，所以我无法用编辑器读取它们。由于visual sfm的文档记录：

使用您自己的功能匹配 1.编写一个包含所有功能匹配项的txt文件 2.将图像（带有功能）加载到VisualSFM中 3.使用“SfM->成对匹配->导入要素匹配” 4.您可以再次使用相同的方法添加功能匹配项

*。这假定您已经检测到这些功能。 *.命令行的相同功能是选项“+导入” *。不要使用“SfM->成对匹配->计算缺少的匹配”，这会进行完全匹配

匹配文件的格式如下：匹配文件=图像匹配=

例如，下面给出了888.jpg和 709.jpg

**888.jpg 709.jpg 24

19 18 24 3651 1511 2899 71 115 201 202 199 1639 2595 210 189 1355 268 241 137 728 1899 193 192 325
139 143 181 261 342 349 373 433 622 623 686 700 745 812 868 951 987 990 1001 1016 1021 1046 1047 1069

其中888.jpg的功能19与709.jpg的功能139匹配**

我使用openCV的sift算法，因此我为每个图像获得一个矩阵，该矩阵具有尺寸#特征x128，并将它们保存为每个图像的.sift

之后，我使用openCV中的匹配算法，得到一个文件，其中包含如下行：
