Definitions
- the invention relates to a method for learning an image recognition algorithm for fault detection in the maintenance of machines with multiple components, a computer program product for carrying out the method and a device for carrying out the method.
- Artificial intelligence algorithms are trained in a learning phase for specific tasks in order to carry them out in a work phase.
- input data is often annotated by people. If, for example, people or objects in photos are to be recognized by the algorithms during the work phase, photos with the objects to be recognized are annotated accordingly during the learning phase by manually marking the objects to be recognized on the photos.
- a reliable algorithm requires a large number of such annotated photos.
- annotation is difficult for a number of reasons. On the one hand, experts are required for the annotation. On the other hand, the amount of data required for training is often too small, for example because the defects to be detected rarely occur.
- the publication DE 10 2018 214 210 Al relates to a visualization device and a method for visualizing the interior or exterior of a vehicle, in particular for planning retrofitting of a vehicle.
- the invention is based on the object of proposing a method for the simplified training of an image recognition algorithm for the maintenance of complex machines.
- the problem is solved by the subject matter of the independent patent claims. Further developments and refinements of the invention can be found in the features of the dependent patent claims.
- the machine is in particular a vehicle, in particular a rail vehicle.
- Capturing image data from the machine in step a. is advantageously carried out with a large number of high-resolution cameras. A detailed image of the machine can then be created.
- a three-dimensional digital model (3D model) of the machine can be created in method step b based on the captured image data.
- the captured image data is first read from the database. Consequently, in method step c. a machine coordinate system is created for the digital 3D model of the machine.
- the machine coordinate system is created from the image data using a suitable algorithm.
- the origin could be a reference point on the machine that is easy to identify for an image recognition algorithm, such as a buffer or a wheel on a rail vehicle.
- the machine is a rail vehicle and the capture of image data of the machine using at least one camera is carried out when the rail vehicle enters a maintenance depot, for example using a so-called camera tunnel.
- the rail vehicle drives through this tunnel when entering the depot and is photographed from several sides, in particular from all sides.
- Fewer cameras can then be arranged in the depot itself and aligned with the rail vehicle standing in its maintenance position, for example in accordance with method step e. to record the position of the serviced component.
- the rail vehicle can be classified into the machine coordinate system, for example, by means of a reference point of the machine that is easy to identify for an image recognition algorithm, for example a buffer or a wheel of the rail vehicle.
- process step a takes place. in the depot with the rail vehicle in its maintenance position. This can also be done for the process step a. the following process steps b. and c. as well as d. apply .
- the depot is then equipped with a large number of cameras, particularly high-resolution ones, in different positions and viewing angles of the rail vehicle. Monitoring the maintenance work in accordance with step d. and recording the position of the serviced component according to method step e. can then be done through the same cameras.
- the maintenance work in particular the servicing, repair or replacement of components of the machine, is carried out by trained service personnel.
- process step e The position of the serviced component is recorded.
- This can be further developed using at least one camera, in particular using at least two cameras, for example using the cameras in the depot when the rail vehicle is in its maintenance position.
