A recently filed patent (Publication Number: US20230298150A1) describes an inspection arrangement for the interior of a passenger vehicle. The arrangement includes at least one image recording unit that captures images of the interior along with any objects present. These images are then analyzed by an image analysis unit, which uses a classification database to assign classification values to the objects based on predefined assignment rules. The arrangement also includes interfaces for inputting and outputting the assigned classification values and/or images to a downstream entity.

The classification values assigned to the objects can include object values, location values, problem values, problem classification values, repair values, image attribute values, and image marking values. This allows for a detailed analysis of the objects and their attributes within the vehicle interior.

The inspection arrangement may also include an image processing unit that performs image processing on the captured images before they are analyzed by the image analysis unit. This ensures that the images are optimized for accurate analysis.

The patent claims also describe different types of recording units that can be used in the inspection arrangement. These include fixed recording units that are permanently attached to the vehicle, movable recording units that can be deployed within the vehicle, hand-held recording units, and semi-autonomous recording units.

Additionally, the inspection arrangement may include a display unit and an input unit for user interaction. The display unit can show the captured images and/or the assigned classification values, while the input unit allows users to modify the classification values or generate additional ones.

The inspection arrangement can be implemented as a distributed arrangement, split over multiple interconnected sub-devices. This allows for flexibility and scalability in the inspection process.

The patent also describes an inspection method that utilizes the inspection arrangement. The method involves capturing images of the vehicle interior, analyzing the images using the classification database and assignment rules, assigning classification values to the images and objects, and outputting the assigned values and/or images to a downstream entity. Users may also be prompted to review and input corrected or additional classification values.

Overall, this patent presents an inspection arrangement and method that enables efficient and detailed analysis of the interior of passenger vehicles, providing valuable information for maintenance and quality control purposes.
