Beschreibung
Zusammenfassung:	An optical device for the verification of pile-driving, comprising a supporting structure, a camera (1), an articulated arm (5) which in turn comprises a point of reference (11), a sensor-illuminator (3) configured to illuminate the surface of the pile (12) and the point of reference (11) by means of a laser illumination pattern, likewise to measure distances with regard to the pile (12); equipment (6) for the processing of the images captured by the camera (1) and of the distances measured by the sensor-illuminator (3); where said equipment (6) is configured so as to measure, on each image captured by the camera (1), a distance Yf between the contrast strip (4) and the point of reference (11) and, by means of triangulation, to calculate the actual distance, Ym, on the pile (12) between the contrast strip (4) and the projection of the point of reference (11) on the surface of the pile (12).
