3DOE Metric 3D photogrammetry system Using ordinary SLR cameras (non-measurement cameras), through multiple two-dimensional photos, based on the principle of industrial close-range photogrammetry, reconstruct the three-dimensional coordinates of key points on the surface of the workpiece, which is widely used in the key points of medium and large (several meters to tens of meters) objects 3D measurement.

Product features :

Compared with the traditional three-coordinate measuring instrument, the system has no mechanical stroke limit, and is not limited by the size, volume, and shape of the measured object. It can effectively reduce the cumulative error and improve the measurement accuracy of the overall three-dimensional data. It can replace traditional laser trackers, articulated arms, theodolites, etc., and there is no tedious problem of moving stations, which is convenient for measuring large workpieces.
