Image analysis as an help for the production of cartographic data must obey some constraints in exhaustively and accuracy that are imposed by the specifications of the production. In the methods presented by researchers, exhaustivity is often tested but accuracy, rarely. For the purpose of building extraction, planimetric and altimetric accuracy are required, we build an hybrid method based on two studies that provide planimetric accuracy--a monocular analysis based on perceptual grouping--and altimetric accuracy--a local statistical analysis of the results of a stereo-matching process. We assessed the accuracy of this method on a class of rectangular buildings and compare our results to the accuracy of the first method that inspired us.
