Safer Stack: Safe Dump of Off-Highways Trucks in Slope Crest Windrows

During operation, the dump truck sometimes needs to operate close to a slope crest windrow. This article aims to present the experimentation of a system, called Safer Stack, to assist the dump truck operator when reversing in front of a slope crest windrow, with the purpose of informing him the safe distance to perform the dump and generating alerts when there is a risk. The system includes computer vision, through image recognition, and distance measurement, through a LiDAR. The information will be used in a graphical interface, with visual alerts and audible alarms for the dump truck operator. Based on the tests carried out, it was confirmed that the combination of technologies in a final solution, since it presented 98% accuracy in the trained scenarios, has the potential to generate highly efficient results and make the operation safer.
