Introduction
Problem description
If the mobile scanning system detects a problem, it displays a notification, warning, or error. Warnings can be resolved by the operator without stopping the mapping session, while errors cannot be resolved without restarting the mapping session.
Types of warnings
The following shows a list of warning messages displayed during scanning:
Code | Description |
WARN_LASER_HORIZ_INVALID_MEAS | Message: Please move the front of the device towards the closest (< 30m) wall. |
Cause: The horizontal laser is not acquiring enough close points for a stable and consistent localization of the device. | |
WARN_SYSTEM_LOAD_HIGH | Message: Please slow down or pause the mapping for a while. |
Cause: The system has a high computation usage. This can be due to a long mapping time. To achieve best results, the system should not work at full capacity. | |
WARN_NODE_LOAD_HIGH | Message: Please slow down or pause the mapping for a while. |
Cause: A software component has a high computation usage. This can be due to a long mapping time. In order to achieve best results, a software component should not work at full capacity. |
Types of errors
The following shows a list of error messages displayed during scanning:
Code | Description |
ERR_IMU_RATE_LOW | Message: Something went wrong! The current dataset will be stopped and saved |
Cause: The sensor is not running with the expected rate. A long mapping time might be the cause for this behavior. | |
ERR_IMU_NO_MSGS_YET | Message: Something went wrong! The current dataset will be stopped and saved |
Cause: The sensor has not sent any data yet. This is most likely a hardware problem. | |
ERR_IMU_MSG_TOO_OLD | Message: Something went wrong. The current dataset will be stopped and saved. |
Cause: The sensor stopped sending data. This is most likely a hardware problem, but a long mapping time might be the cause for this behavior. | |
ERR_NODE_NOT_RUNNING | Message: Something went wrong! The current dataset will be stopped and saved. |
Cause: A critical software component is not running. | |
ERR_IMU_VALUES_NAN | Message: Something went wrong! The current dataset will be stopped and saved. |
Cause: The IMU is sending invalid data. This is most likely a hardware problem |
Troubleshooting procedure
From the Unexpected error screen, click Save dataset to manually stop and save the current dataset. The NavVis VLX automatically saves the dataset after 20 seconds.
Once the dataset is saved, restart the device by pressing the power button.
Start a new dataset.
