Zero defect labels required: train on good parts only, register frames with OpenCV 5, run a PatchCore/anomalib model through the DNN engine, and choose reject thresholds from escape and false-reject costs instead of best-F1.

Photoreal 3D capture got cheap, but the poses did not. A production pipeline: OpenCV 5 blur/exposure/parallax curation, an intrinsics prior from ChArUco, honest SfM statistics, mesh-versus-splat selection, metric scale from markers, and an error budget you can put in a report.

A production guide to running vision in a browser tab: trimming your own OpenCV.js WASM build, SIMD and thread gating, worker-based frame capture with WebCodecs, a document capture-assist pipeline, ONNX Runtime Web on WebGPU, and when to give up and go server-side.

Every rescued vision project starts with “it worked last month”. Pinning the whole stack, building a representative golden-frame corpus, tolerance-based assertions instead of pixel equality, per-slice model-promotion gates, containerised CI, and production drift monitoring that closes the loop back into the test suite.

A measurement-first guide to OpenCV 5 performance: building a per-stage frame-time budget, reading cv::TickMeter and py-spy honestly, when UMat/OpenCL and CUDA actually pay off, hiding host-device copies, G-API graphs, and the threading mistakes that silently halve throughput.
