Abstract

A riveting method that includes riveting a first aircraft part to a second aircraft part. The method includes capturing a plenoptic image of the rivet and at least one of the first part and the second part in the vicinity of the rivet, by a plenoptic imaging device secured to a riveting head, after riveting the first part to the second part. The method includes detecting the positioning and the surface condition of the rivet, from the plenoptic image captured by the imaging device.

First claim

The invention claimed is:

1. A riveting method comprising riveting a first aircraft part to a second aircraft part, by means of a riveting system comprising:
a riveting tooling configured to assemble the first part to the second part by riveting, wherein the riveting tooling comprises a riveting head that is intended to come into contact with the first part and/or the second part, and
a plenoptic image acquisition device, wherein the plenoptic image acquisition device is secured to the riveting head,
the riveting method further comprising:
capturing a plenoptic image of a rivet and of the surroundings of the rivet, by the image acquisition device, after riveting the first part to the second part, and
detecting the positioning and the surface condition of the rivet, from plenoptic image captured by the image acquisition device.

2. The riveting method according to claim 1 , comprising the three-dimensional reconstruction of the rivet and of the surroundings of the rivet.

3. The riveting method according to claim 1 , comprising comparing the detected positioning of the rivet to a reference position of the rivet and comparing the detected surface condition of the rivet to a reference surface condition of the rivet.

4. The riveting method according to claim 3 , comprising signalling a positioning and/or surface condition defect of the rivet.

5. The riveting method according to claim 4 , comprising signalling a positioning and/or surface condition defect of the rivet, when a rivet head flushness defect and/or a notch of the rivet have been detected.

6. The riveting method according to claim 1 , wherein the rivet is a blind rivet and/or wherein the rivet has a head intended to be flush with a surface of the first part and/or a surface of the second part after riveting.

7. The riveting method according to claim 6 , rein the rivet s a countersunk head rivet.

8. The riveting method according to claim 1 , further comprising:
riveting a first rivet to assemble the first part to the second part, and
riveting a second rivet to assemble the first part to the second part.

9. The riveting method according to claim 8 , comprising comparing the detected positioning of the second rivet to the detected positioning of the first rivet and/or comparing the detected surface condition of the second rivet to the detected surface condition of the first rivet.

10. The riveting method according to claim 7 , comprising establishing rivet placement statistics.

11. A riveting system for aircraft, comprising a riveting tooling configured to assemble a first aircraft part to a second aircraft part by riveting, the riveting tooling comprising a riveting head intended to come into contact with the first part and/or the second part,
wherein the riveting system comprises a plenoptic image acquisition device, configured to capture a plenoptic image of the rivet and the surroundings of the rivet after riveting the first part to the second part by the rivet, wherein the image acquisition device is secured to the riveting head.

12. The riveting system according to claim 11 , wherein the riveting head comprises:
a rotary barrel which includes housings distributed circumferentially around a longitudinal axis of the riveting head, and
riveting tools which are different from each other and which perform various operations involved in riveting,
wherein the riveting tools are intended to be housed in the housings of the barrel, wherein the image acquisition device is housed in one of the housings of the barrel.

13. The riveting system according to claim 12 , wherein the riveting tools comprise a tool for drilling an orifice passing through the first part and the second part, for inserting a rivet pin and/or a rivet body, and/or a riveter.
