Abstract
ABSTRACT In this article, authors attempt to estimate the volume of rock pieces using the laser scanning technique supported by measurements from the RGB camera. Laboratory tests were performed, based on which the error in estimating the size of the fragments was determined based on the available perspectives. With a known estimation error, the volume of the ore chunks was estimated based on data from a single perspective. The presented methodology makes it possible to determine a unital numerical measure to compare Hydraulic Breaker Hammers (HBH) and Lekatech Electric Hammer (LEH) by estimating the energy consumption determined through electric current measurements.
