sift+lightglue #122

Open LXXIANG12 opened 6 months ago

sift描述符是128维，lightglue描述符是256维，我该怎么使用SIFT+lightglue呢？

好像训练的时候可以改

LXXIANG12 commented 6 months ago

希望训练的时候可以修改

官方公布了SIFT+lightglue的预训练权重，我想先用这个模型试试看效果，但是使用过程报错了 image 以下是我的示例： image 我第一次使用不知道改哪里

If I understand your issue correct (please post your issues in english), you want to use SIFT with LightGlue. You need to load the correct weights in LightGlue, with:

extractor = SIFT(max_num_keypoints=None).eval().cuda()  # load the extractor
matcher = LightGlue(features='sift').eval().cuda()  # load the matcher

Note that you need to specify which weights to load in the constructor of LightGlue (the SIFT setup is defined here).
