    2. COSo, from the Fundamental Matrix, I calculated the essential matrix using E=K2'*F*K1. Then, my SVD needs a diagonal matrix such as (s,s,1) but my diagonal matrix is diag(1.3, 1.05, 0). I assume it is good enough and then find translation using T = last column of U and R could be U*D*V' or U*D'*V'. If i find out which of these combinations is the right one, I will have P1 = [I|0] and P2 = [R|T]. So, I read the scale is an ambiguity which can never be determined. I need to know the scale since I am trying to estimate the exact 3d co ordinates of the objects. Am i in the right direction?

    3. COMy main concern was to obtain the projection matrices P1 and P2. I see that with the help of fundamental matrix F, I can only obtain canonical projection matrices but these are not up to real scale. Can you kindly guide me how I could obtain P1 and P2 which are good for real scale.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
