According to the present invention, a three-dimensional resolution target is attained together with a relative system for the characterization of the surface defects/indications via indirect visual examinations of various surfaces. The object of such target is to compare and evaluate the resolution of the image acquired from an image acquisition unit.The target comprises incisions and/or projections organized in groups on a surface with three-dimensional geometric shapes that protrude from said surface and/or are embedded in said surface.The system of the present invention is employed for the visual examination characterization and exploits said three-dimensional target. In its basic form, the system comprises an image acquisition unit and at least a memory into which the acquired images are sent and preserved. Other embodiments provide for the use of drones that mount said acquisition unit and which can physically position the target on the surface to be examined.

System for remote technical assistance in real time adapted to comprise a plurality of elements suitable for showing, to a remote control unit, the objects observed by an operator engaged in maintenance interventions, simplifying any type of intervention, whether ordinary or extraordinary; said system being suitable for sending the collected information to the smartphone of the operator, via a wireless connection; all the information being then shared with said control unit via an internet connection provided by the smartphone; this system being therefore suitable for putting the operator in communication with the specialized staff located remotely, allowing the staff to create references and tags on the video received in streaming from the operator, simplifying any type of communication.
