Abstract

The invention discloses a three-dimensional laser scanner auxiliary support and method for bridge bottom form measurement, and the support comprises a mobile station which is disposed at a position, close to a bridge handrail, of a bridge; a stand column, wherein the bottom end of the stand column is connected with the movable table, the upper end of the stand column is connected with one end of a horizontal telescopic rod, and the horizontal telescopic rod can stretch out and draw back in the direction of the outer side of the bridge handrail; a vertical telescopic rod, wherein the upper end of the vertical telescopic rod is connected with the outer end of the horizontal telescopic rod, the bottom end of the vertical telescopic rod is connected with a scanner placing frame, and the scanner placing frame is used for placing a three-dimensional laser scanner. The technical problems of poor accessibility, incomplete data, low working efficiency and the like when the three-dimensional laser scanner is used for measuring the shape of the bottom of the bridge are solved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a three-dimensional laser scanner auxiliary bracket and method for shape measurement of bridge girder bottoms. Background technique [0002] Three-dimensional laser scanning is a fully automatic, all-round, high-precision three-dimensional space shape scanning technology. This technology uses a 3D laser scanner to obtain the spatial coordinate information of a large number of points on the bridge floor, and analyzes the data features to identify its spatial form. At present, the method of obtaining point cloud data of the bridge floor by using the 3D laser scanner is mainly to sample the bridge deck or the bottom of the beam at multiple stations. It is difficult to directly scan the bottom of the beam when performing laser scanning on the bridge deck, while selecting a station near the bridge site for scanning is easily affected by the site terrain and the excess under th...
