IV.
Light Sources and Algorithms
What to look for regarding light sources and algorithms.
Based on industry best practices for machine vision, here is the approach to lighting and algorithms: **Lighting**—Illumination is the core of visual inspection (changing the lighting setup can drastically alter detection rates); dimensions for ring, flat, and dome lights should exceed the field of view (FOV) by 10–20%, while bar lights should be 20–30% longer than the FOV. **Cameras**—5-megapixel industrial cameras paired with industrial lenses (focal lengths of 8, 12, 16, 25, 35, and 50mm available); line-scan cameras for high-resolution, wide-FOV continuous imaging (suitable for automotive parts, 3C electronics, stamping, and plastics); specialized cameras (IP67 waterproof/dustproof ratings, MTBF >50,000 hours, suitable for harsh outdoor environments). **Algorithms**—Deep learning for precise recognition (micron-level defect detection and stable operation in complex conditions); AI algorithms combined with multi-view optical inspection (eliminating missed detections and false positives); proprietary AI algorithms for real-time, precise classification and verification of massive defect datasets. **Inspection Dimensions**—Appearance, dimensions, weld points, character reading, and positioning guidance (robot guidance, dimensional measurement, code scanning, and character inspection). **Customization**—Lighting solutions, camera selection, and algorithm models are all fully tailored (we do not offer generic machines; we build practical, customized systems). The “four-part formula” for lighting and algorithms: light dimensions 10–30% larger than the FOV; cameras selected based on required defect precision; algorithms trained on specific samples; and solutions customized to operating conditions—only when these four elements are properly matched can detection rates meet the required standards.
V.
Vendor Selection and Acceptance
How to select a manufacturer and conduct acceptance testing.
Based on industry procurement practices, here is how to make your selection: **Process**—A four-step guide to purchasing visual inspection equipment (define inspection scenarios, evaluate technical compatibility, assess service coverage, and verify qualifications); **Pre-selection**—Request a prototype for real-world testing to avoid production line rework (lighting setups and algorithms can cause vast differences in detection rates) and provide actual defective samples (along with a photo list of defect types); **Qualifications**—Look for “Specialized, Refined, Unique, and Innovative” (SRUI) status, authorized distributorships (e.g., LMI, FOCALSPEC, ZIVID, Hexagon), 15 years of vision industry experience, and participation in standard drafting (such as the MIIT White Paper on AI Industrial Quality Inspection Applications); **Service**—On-site operational compatibility and post-sales implementation capabilities (don’t prioritize low price alone when choosing industrial vision systems), long-term maintenance, and continuous algorithm iteration (using on-site sample feedback); **Acceptance**—Actual testing of detection, missed detection, and false alarm rates (e.g., Jiebaili’s false alarm rate is <0.05%), precision (0.01mm/micron level), speed (1,000 units/minute), stability (IP67 rating, MTBF of 50,000 hours), and system integration (PLC/MES interfaces); **Contract**—Clearly specify the inspection checklist, acceptance criteria, delivery schedule, warranty, and post-sales response terms.
**The Five Key Gates for Vision Vendors:** Prototype testing, lighting/algorithm solutions, qualification/authorization, service coverage, and acceptance criteria—make payment only after passing all five gates.
