1. A system for monitoring a track for traction of a vehicle on a ground, the track being mounted around a plurality of wheels, the track comprising a ground-engaging outer surface configured to engage the ground and an inner surface opposite to the ground-engaging outer surface, the track including elastomeric material to flex around the wheels and a reinforcement embedded in the elastomeric material, the system comprising:
an interface configured to receive data regarding a plurality of images of the track; and
a processor configured to:
create a three-dimensional (3D) model of the track from a 3D point cloud generated by processing the data of the plurality of images of the track;
perform a 3D model analysis comparing the created 3D model of the track to a design 3D model of the track by performing volumetric analysis to obtain a deterioration result of the 3D model analysis;
perform a two-dimensional (2D) image analysis by performing image acquisition, image processing, feature extraction, and feature classification, on images generated from the created 3D model of the track to obtain a deterioration result of the 2D image analysis;
generate information on a state of the track by combining the deterioration results of the 3D model analysis of the track and of the 2D image analysis of the track, and
determine that a deterioration threshold event relating to at least one of an exposure of the reinforcement and a crack in the elastomeric material of the track, has occurred based on the information on the state of the track;
wherein the processor is further configured to issue a signal based on the determination to inform a user of the system of an action to be performed in respect of the track.
