Ineco has designed a new visual inspection device for railway track maintenance. The Graphical Inspection of Apparatus and Track Device (in Spanish, DIGAV) allows, through the use of artificial intelligence and specific algorithms, for the automatic identification, detection and evaluation of defects.

The device has seven conventional cameras in addition to three stereoscopic cameras, which allow the generation of 3D models. From the information collected by these devices it is possible to visualise the rail from all angles, as well as to perform measurements on the generated models.
The collected information improves the evaluation of the condition of the track since it allows, for example, seeing in detail the web of the track, which is not possible with on-board equipment that only captures zenithal information of the track body.
Its continuous shooting system makes it possible to increase the inspection speed to 3.5 km/h, which reduces the duration of track runs by 30-40% (in an area of 200 km of double track we would go from the current ten weeks to less than seven weeks). This generates an increase in the quality of graphic and analytical data collection that does not depend on the human factor.
Artificial intelligence
Thanks to the analytical processes, based on artificial intelligence and image processing algorithms, it is possible to process all the information collected and automatically detect defects such as the lack of an asset, its correct position, the automatic inventory of assets or the evaluation of the ballast shoulder.
All the information collected is stored in the servers allowing its evaluation and analysis and opening the possibility of the development of predictive maintenance models or the generation of digital twins.
