hello i am doing a 3D riconsturction of a simple object(rail pantograph) by intelrealsense D415, i scan the object, moving around the patograph with the camera, after scan i reproduce a pointscloud, and i open this pointsclound in meshlab after i take the coordinate of the points and i plot the graph with matlab and i got the graph of the reconstruction, but when i compare the graph with real size i have error,  can someone help me?

thanks

    Hi Elia Cogni01  When exporting a pointcloud as a ply file from the RealSense SDK and then importing the ply into a 3D modelling tool such as MeshLab, the scale in the 3D software should be set to the same scale that was being used in the RealSense SDK when the data was exported or the imported model will be incorrectly scaled.  For most RealSense 400 Series camera models including D415, the default scale is 0.001
