Excavation pits—progress estimation and cause of delay identification

Abstract This work presents a method for automated excavation speed and progress estimation. First, measure the of an pit is taken from literature evaluated regarding possibility automation. For each possible parameter, extraction algorithm presented. The used system autonomous excavator arm backhoe loader where hardware software described. An experimental evaluation presented approach has been done with small trench, including multiple digging cycles. resulting measurements seem to include some systematic errors which could be identified suitable sanity checks implemented, removing erroneous measurements. remaining were determine compared values experienced amateur operators. relevant parameters are then sent web application called “DiBa” notice potential delay. If measurement smaller or larger than expected fault identification in DiBa.
