Resources
Use these notes to prepare camera, lens, lighting, 3D vision and barcode-reader requirements before asking for a factory recommendation.
Direct use
Deyi Vision resources now separate 4 paths: basics, selection guides, comparisons and RFQ checklists. Each path leads back to product families and engineering review inputs.
RFQ intake route
Integrated design tools are the intake layer before model selection: define field of view, resolution target, lighting risk, barcode read-rate, trigger method and acceptance criteria together, then route the request to the right camera, smart camera, line scan camera, industrial barcode reader or full vision inspection system.
Use field of view, working distance, defect size, line speed and interface notes as one design brief before asking for camera, lens, lighting or barcode-reader selection.
CalculatorTurn smallest defect or tolerance into a starting resolution route before choosing industrial cameras, smart cameras or machine vision lenses.
ChecklistCollect sample images, good/bad parts, acceptance criteria, PLC signals and reject logic so the factory reply is based on evidence instead of model-number guessing.
