Questions about the key points on Megadepth test images #43

Hi,

Thanks for providing such elegant code. I ran the megadeath test script and saved the matches in files. I found the key points' locations are shifted from the input images. Do you have any ideas to solve it?

Best, Yongqing

Hi, it looks as though the coordinate systems used are different, maybe resized for DKM? Could you show me the code you ran?

I figured it out. I divided it by scale1 and scale2, which are computed by

scale1 = 1200 / max(w1, h1)
scale2 = 1200 / max(w2, h2)
