Auxiliary folding crosspiece with leveling system for basic procedures rectification bridge inspection factory.

摘要

The present invention relates to the development of an auxiliary tool consisting rectification in a light, foldable and metrically stable to serve as carrier tool control points, whose position is calibrated laboratory crosshead, and is held by a leveling system. This invention is developed so it can be used in processes for obtaining actual metrics during the execution of inspection structures by photogrammetric rectification.
