One of the most important challenges in the computer vision has long been to obtain three-dimensional
models from the information given by a projection of the model. In this work we show an automatic system
which allows obtaining three-dimensional models from entities that represent the conical projection of a
polyhedral model with normalon or quasi-normalon typology. The results obtained on a total of 160 tests,
with a success ratio of 100%, make the method a proposal to be considered for obtaining models from conical
perspectives automatically
