measuring points from the TLS/GBL centre

Post by kyleramseyrca »

Hi there, looking to measure points from the LiDAR sensors origin, but can't get my head around changing the pointcloud's centre/origin to the centre found on the TLS/GBL, then using point picking to get the x,y,x values of the point from the TLS/GBL centre.

Was wondering if anyone has done anything similar and got any tips?

Normally, if it's only the origin, you should be able to select the sensor entity, use 'Edit > Sensor > Edit' and the read/copy its center ('C' row = Cx Cy Cz).

Then use the 'Edit > Apply transformation' tool and pate the opposite values in the 'Translation' fields of the second tab (Axis, Angle). Translation = "-Cx -Cy -Cz"

And you can double check that it worked by looking again at the sensor parameters (Edit > Sensor > Edit). The center should be now at 0, 0, 0.
