Abstract: A system is configured to receive an indication that an apparatus in a first assembled state should comprise a component with a first digital fingerprint and a component with a second digital fingerprint. The system is configured to receive video footage of apparatuses in the first assembled state. The system is configured to isolate an image of an apparatus in the first assembled state. The system is configured to split the image into a frame comprising a first component and a frame comprising a second component. The system is configured to identify feature points and to determine that the first set of feature points matches the first digital fingerprint and that the second set of feature points matches the second digital fingerprint. The system is configured to update a component database.

Abstract: A system is configured to receive video footage of evaporator coil slabs after they exit an automated coil brazer. The system is further configured to convert the video footage to greyscale and isolate frames from the greyscale video footage. Each frame comprises an image of a different evaporator coil slab. The system is further configured to generate a first digital fingerprint comprising a binary feature vector for each point in a first subset of feature points from the first frame, and generate a second digital fingerprint comprising a binary feature vector for each point in a second subset of feature points from the second frame.

The system is further configured to convert the video footage to greyscale. The system is further configured to isolate frames from the greyscale video footage. Each frame comprises an image of a different evaporator coil slab. The system is further configured to identify a plurality of feature points in a first frame and a plurality of feature points in a second frame. The system is then configured to determine that a subset of features points in each frame are rotationally invariant. The system is further configured to generate a first digital fingerprint for each frame from a binary feature vector for each point in the subset of feature points determined to be rotationally invariant.
