Optics is the one part of a vision pipeline you cannot fix in software. How to size field of view, focal length, aperture and exposure from the defect you must detect — then verify the hardware you bought with an ISO-12233-style slanted-edge SFR/MTF measurement in OpenCV 5.

OpenCV 5 moved point-cloud work into the new 3d module. Here is the full path from a structured-light or active-stereo capture to a cleaned cloud, a plane-removed bin, ICP-registered CAD models and a 6-DoF grasp pose with an error budget you can put in a quote.

Bounding boxes cannot answer "how much". This walkthrough runs semantic and YOLO-style instance segmentation through the OpenCV 5 DNN engine, cleans the masks with morphology and connected components, converts pixels to mm² through a calibrated scale, and sets out the area error budget and validation protocol behind the number.

Why stalled computer vision projects are almost always data problems: pHash and embedding dedup in OpenCV 5, annotation guides with a measured agreement ceiling, model pre-labelling, an uncertainty-plus-diversity active-learning loop, and a frozen golden test set that tells you when to stop paying for labels.

How to wire an OpenCV 5 pipeline into a ROS 2 Jazzy/Kilted robot stack without paying for it in copies: cv_bridge without the ABI surprises, intra-process composition, image_transport compression, deadline QoS, and a latency budget you can quote to a customer.
