Abstract
An automated signaling equipment inspection system is provided. The system includes signaling equipment, a LiDAR imaging device permanently installed close to the signaling equipment at a position and with an orientation allowing complete imaging of the orientation and configuration in space of the signaling equipment and of any potential movement of the signaling equipment during its operation, an image data processing device for detecting a non-conformity of the signaling equipment, and a reference image database storing reference image data of the signaling equipment. The LiDAR imaging device is configured to scan the signaling equipment to obtain real image data thereof. The image data processing device is configured to detect a non-conformity of the signaling equipment by comparing the real image data with reference image data taken from the reference image database.
