| • | Initialize with
ortho/weak perspective model then iterate |

| • | Derive
expression for weak perspective as a perspective |
||||||||||||||
| projection plus a
correction term: |
|||||||||||||||
| • | Basic procedure: |
||||||||||||||
| – | Run Tomasi-Kanade
with weak perspective |
||||||||||||||
| – | Solve
for i
(different for each row of M) |
||||||||||||||
| – | Add
correction term to W, solve again (until convergence) |
