LaseASTO

LaseASTO divides the work area into two monitoring areas: a danger and a safety zone. In the danger zone, the loading of containers takes place. If a person is in this area, an emergency shutdown of the crane system is carried out. If, on the other hand, the person is in the safety zone, container handling, for example, can be carried out safely.

At least two multi-layer laser scanners are used in this system, which are mounted, for example, on the container crane above the transfer area from the crane to the transfer area. These scan the transfer or “monitoring area”. The measured 3D point clouds, i.e. scan data from both sensors and produce a scenario representation in the monitoring area under the crane.

Segmentation of the obtained 3D point cloud provides the individual objects’ length, width and height. A truck or driver classification is based on size information and other attributes, such as the centre point and the number of points that make up the detected object.  

Once the driver or other objects, for example, has been detected, they will be tracked by LaseASTO until they reach a safety zone within the monitoring area, return to the driver’s cab, or leave the area of operation. These evaluations are continuously transmitted to the crane driver, who uses this information to determine when loading or unloading a container is safe. 

Alarms are not triggered if boxes or the like have already been detected in the work area. Only persons trigger an alarm here if they are not in the safe zone or if others enter the working area from outside.
