Problem 

Processing fails because of the following error: 

ERROR: Could not process dataset '/media/data/home/ti_svr/datasets_rec/2019-11-189': Command 'nv_colorcloud --input=/media/data/home/ti_svr/2019-11-189/pointcloud.ply --output=/media/datasets_proc/2019-11-18_23.50.29/pointcloud.ply.tmp.ply --info-dir=/media/datasets_proc/2019-11-18_23.50.29/info --sensor-frame=/media/datasets_rec/2019-11-18_23.50.29/sensor_frame.xml --res=0.01 --color-extrapolation=fill' non zero exit status 137.returned

Solution

The non zero exit status error is usually associated with a memory issue. The RAM is low for the size of the dataset. You can compare the RAM size listed in the post-processing log after the processing starts with the minutes included in the dataset.

  • For short NavVis M6 mappings: ~32GB RAM is necessary
  • For long NavVis M6 mappings: ~64GB RAM is necessary
  • For NavVis VLX mappings: 32GB - 128GB RAM is necessary
Host:
  CPU: logical cores: 8 / physical cores: 4
  Memory: physical: 15.5 GiB, available: 12.0 GiB, 22% used
  Storage: total: 457.0 GiB, used: 250.2 GiB, free: 183.5 GiB, 58% used


Try the following solutions to solve the problem:

  • Clear the RAM memory
  • Process the dataset on another machine with higher RAM
  • Cut the dataset in half at a plausible position of the dataset using the NavVis tool nv_cut-dataset. Please see the System Software documentation: https://support.navvis.com/docs/mapping/
