我有一个来自相机的2个连续图像,我想估计相机姿势的变化:

我计算光流量:

Const MAXFEATURES As Integer = 100
imgA = New Image(Of [Structure].Bgr, Byte)("pic1.bmp")
imgB = New Image(Of [Structure].Bgr, Byte)("pic2.bmp")
grayA = imgA.Convert(Of Gray, Byte)()
grayB = imgB.Convert(Of Gray, Byte)()
imagesize = cvGetSize(grayA)
pyrBufferA = New Emgu.CV.Image(Of Emgu.CV.Structure.Gray, Byte) _
    (imagesize.Width + 8, imagesize.Height / 3)
pyrBufferB = New Emgu.CV.Image(Of Emgu.CV.Structure.Gray, Byte) _
    (imagesize.Width + 8, imagesize.Height / 3)
features = MAXFEATURES
featuresA = grayA.GoodFeaturesToTrack(features, 0.01, 25, 3)
grayA.FindCornerSubPix(featuresA, New System.Drawing.Size(10, 10),
                       New System.Drawing.Size(-1, -1),
                       New Emgu.CV.Structure.MCvTermCriteria(20, 0.03))
features = …
