Yes, as long as the top of the load is well clear of the Scan Head and there is some drop-off below the level of the sides at the front and rear of the tray.
No. Loads must be uncovered during scanning.
No, not in general. The minimum tray capacity must be at least 3m³
Yes, generally. The trailers must meet the minimum size requirements and be of a open, regular shape.
If the quantity of steam is enough to significantly disturb the visibility of the load surface, then a “Visual Pollution” error will be reported and no measurement computed. This can generally be resolved by waiting a couple of minutes or so for the steam to settle and re-scanning.
The LVS is an optical system and so can be affected by high levels of visual “pollution” in the air. The system may not be able to operate under the following conditions: heavy dust, dense fog, severe storm conditions, snowing. In these cases the system is designed to report a “Visual Pollution” error rather than give poor results. Note that normal levels of rain are not a problem.
The LVS is designed to work with ‘particulate’ materials which form heaped load profiles. This includes most quarried rock materials, sand, bark, woodchip and other landscaping materials, fertilizer, grains, powders and so on. The system is not intended for use on large rocks, boxes or other regular shaped objects. Some materials such as wet coal or translucent/clear materials may not have a high enough reflectivity to work with the system.
Yes. Our system has been tested with larger dump trucks and we are currently developing standard solutions for this market.
The LVS does not measure weight. It measures load volume in cubic metres or cubic yards. The weight of the load can be estimated if the bulk density (mass-to-volume ratio) of the load material is known. Some typical bulk densities are listed here.
