2012-08-07 20:00:53 -0600 | asked a question | Wrong Position From cvGoodFeaturesToTrack()! Hi, All We are trying to locate corners with cvGoodFeaturesToTrack. The version is opencv 2.3.1. The test picture is a 24-bit bmp file, which is manually made with Windows Pen. So you know, it is a "perfect" picture. It has no noise. There is only one inner corner in the picture. It looks like BMW logo. And this is the code: The code told me that the corner lies in (101, 60). However, it should be (94, 67). We drew a circle at (101, 60) and we found it doesn't overlap the corner! Why the function returns a wrong position? Thanks! |
