A parcel is placed underneath the Tricolops dimensioner, but it is not dimensioned properly.
The most common causes are:
The object is too large. The object is outside the system's dimensioning capabilities. Use alternative means to enter in dimensions.
The object is not fully in view. The object is within the system's dimensioning capabilities, but not fully in the view of the camera. Adjust the object's position so that it is fully given to the camera.
The Tricolops dimensioner is not set up properly. Remove all objects from the trigger area. If the status does not say "Place Object In Trigger Area", follow this guide to set the trigger area.
The environment is too cluttered. On rare occasions, Tricolops will be unable to dimension parcels if the surroundings are cluttered. Make sure there are visible gaps between the parcel being dimensioned and its surroundings.
