Notes:
Nowadays some measurement tasks are usually made by the joint use of differentsystems, techniques, even sciences, trying to find the best results together with less work time. Thisis the case of close range photogrammetry and laser distancemeter. It is possible to find some workswhere they are applied together in so different sceneries as architectonic conservation, civilengineering, building, etc. One of the scopes where these techniques can be applied is in themeasurement of facades of buildings in construction [1,2]. During the constructive process it isnecessary to make periodic measurements, and also during the whole life of the building, as acontrol tool [3]. At the present day some of these measurements are hand-made, with the risk ofhaving an industrial accidents in some situations. In this work we present a methodology based on aphotogrammetric - distancemeter joining measure system, in order to semi-automate somemeasurement procedures in building construction. The system consists of a semi-rigid calibratedsupport putting up a laser distancemeter and a digital camera, called CaM-DisT®. The support wasspecifically designed for this kind of application. The development of the system was made in foursteps: establishment of the mathematical background; design of the support; construction of thesupport; and calibration of the complete system. The calibration process was made by two differentalternatives which are xpounded this contribution in detail
