Abstract
An apparatus for characterizing an object is provided. The apparatus includes interface circuitry configured to receive an image stream of an event-based vision sensor. The image stream includes a plurality of images for consecutive time instants during the capture of a surface of the object. The images of the image stream each include a plurality of image pixels indicating whether a corresponding sensor pixel of the event-based vision sensor measured an event for the respective time instant. In addition, the apparatus includes processing circuitry configured to determine the presence of a crack on the surface of the object based on the image stream.

An apparatus for characterizing an object, the apparatus comprising:
- interface circuitry configured to receive an image stream of an event-based vision sensor, wherein the image stream comprises a plurality of images for consecutive time instants during the capture of a surface of the object, wherein the images of the image stream each comprise a plurality of image pixels indicating whether a corresponding sensor pixel of the event-based vision sensor measured an event for the respective time instant;
- and
- processing circuitry configured to determine the presence of a crack on the surface of the object based on the image stream.
A method for characterizing an object, the method comprising:
- receiving an image stream of an event-based vision sensor, wherein the image stream comprises a plurality of images for consecutive time instants during the capture of a surface of the object, wherein the images of the image stream each comprise a plurality of image pixels indicating whether a corresponding sensor pixel of the event-based vision sensor measured an event for the respective time instant;
- and
- determining the presence of a crack on the surface of the object based on the image stream.

- and
- processing circuitry configured to:
- determine whether a deflection of the object occurred based on the image stream;
- and
- if it is determined that a deflection of the object occurred, increment a counter for counting a number of load cycles to which the object has been subjected.
