Import trajectory file with time data
Posted: Mon Oct 21, 2024 1:03 pm
Hi there,
I am working on data collected using the FARO Orbis in the Amazon. I am hoping to voxelise the data using AMAPvox to obtain forest structural information. As such, I want to use CC to clip the transect out of the whole point cloud. I need to also clip the trajectory file (traj.txt output by FARO Connect) to the exact same limits as the point cloud.
On importing the traj.txt file, clipping and exporting both I am finding that the time values in the trajectory file have been rounded up to the nearest integer, i.e. from 1724180873.92625 to 1724180873.00000 because, in order for them to be imported, I am classifying these time values as scalar field type on import.
In order for the time values to correspond to the point cloud times they have to be time matched, so rounding the time unmatches them. Is there a way that I can import the trajectory file to CC, including the time data, retaining the time data exactly as it is? I have tried some of the other options from the drop-down menu in the ascii file import window (where it is possible to choose attribute type for each column of the data), however none of these seem to allow to just import the data rather than use it. I had tried to import them as labels but labels aren't exported so that didn't work.
Thanks
