The present invention relates to a system and process carried out after a process of separating fragments of steel from pieces of ore that come out of a semi-autogenous grinder for grinding ores, and which consists of a system formed by one or more instruments for capturing images, each one being sensitive to light of different wavelengths, which point to the surface of an element for receiving the steel fragments or a channel that receives the steel balls and the fragments thereof from the separation process, through which the steel balls and fragments thereof move when they are discharged from this process, with the possibility of directing each image sensor such that it is not parallel to the others.

By digitally processing the images obtained with the one or more sensors, the dimensions and morphology of the balls and ball fragments discharged from the separation process can be determined.

A computer-implemented point-cloud data acquisitioning method for acquiring point-cloud data of the inside of a mining equipment. The method includes the step of acquiring from a sensor, a first dataset and a second dataset, wherein each dataset includes datapoints at coordinates. The method extracts features from the first and second dataset and aligns the first and second dataset using the extracted features. The first and second dataset are aligned into a point-cloud data. The geometry of the mining equipment is estimated based on the point-cloud data and the point-cloud data is used to identify a region of the estimated geometry indicating insufficient data.
