Machine vision that inspects, measures and sorts on your line.
Cerox Engineering designs and builds camera-based inspection systems for factories: shade segregation, fabric inspection, label and code checks, measurement and grading. We also supply the cameras and lenses behind them.
What we build
Vision Systems We Build
Stations designed around one job on the line, added to the equipment you already run.
Shade Segregation
Sort fabric rolls, cut panels and washed garments into buyer shade bands with CIELAB measurement and 555 codes.
Learn moreVision Sorting System
Sort by color, size, or defect at line speed.
Learn moreVision Inspection Cell
Checks dimensions, print, and assembly, pass/fail per unit.

The inspection and measurement problems a camera can take over from the human eye.
Automated Fabric Inspection
Camera-based fabric inspection for woven and knit rolls. Line-scan cameras detect holes, stains, slubs and dropped stitches across the full width, map every defect and grade rolls to the 4-point system.
Barcode, 2D Code & OCR
Industrial code reading and traceability: read and grade barcodes, QR and Data Matrix codes to ISO/IEC 15415 and 15416, verify printed date and lot codes with OCR, and reject every unreadable or wrong code.
Label & Packaging Inspection
Vision inspection for labels, caps, fill levels, seals and cartons. Check the right label is present, straight and legible, caps are fitted, containers are filled and packs are sealed, on every unit at line speed.
Dimensional Measurement
Non-contact measurement of lengths, diameters, hole positions, gaps and profiles with telecentric optics and 3D laser profiling. Measure every part in-line, pass or fail it against tolerance, and log data for SPC.
Surface Defect Inspection
Automated surface inspection for scratches, dents, cracks, porosity, stains and coating faults on metal, plastic, rubber and glass. Specialised lighting and deep learning find cosmetic and functional defects on every part.
Glossy & Moulded Part Inspection
Vision inspection for glossy and injection moulded parts: scratches, sink marks, short shots, flash and gloss faults, found with deflectometry and dome lighting.
Automatic Counting
Automatic counting of parts, garments, cartons and packs by camera, sensor or weight, with counts sent to your PLC or ERP. Designed and built in Sri Lanka.
PPE & Safety Monitoring
AI on your CCTV detects missing helmets, vests, gloves and hairnets, danger zone entry, forklift near misses and smoke. Processed on site, PDPA ready.
Automated Weighbridge & ANPR
Unmanned weighbridges with number plate recognition, load photos and automatic gross and tare matching, for tea factories, cement plants and quarries.
Tile Shade & Defect Grading
Automated ceramic tile grading: CIELAB shade sorting, calibre measurement and detection of cracks, chips, pinholes and glaze defects, to ISO 10545-2.
Rubber Glove Inspection
Automated inspection of latex and nitrile gloves for holes, tears, thin spots and stains, on the former line or after stripping. Supports EN 455 and AQL.
Garment Measurement & Stitch QC
Camera measurement of every point of measure against the spec sheet, plus seam inspection for skipped stitches, puckering and open seams. For apparel QC.
Tea Leaf Quality Assessment
Computer vision that estimates the fine leaf share of green tea leaf at factory intake, on the device without internet. In development; trial partners wanted.
Empty Bottle Inspection
Empty bottle inspection for returnable glass: chipped finishes, cracks, dirt, foreign objects and leftover liquid caught between the washer and the filler.
Vision-Guided Robotics
Give robots eyes: 2D and 3D vision locates parts on conveyors, in trays and in bins so robots can pick, place, pack, palletise and tend machines without precise fixtures. Hand-eye calibration and conveyor tracking included.
Assembly Verification
Vision error-proofing (poka-yoke) for assembly lines: confirm every component is present, correct, oriented and seated, count parts, and keep an image record of each assembly for traceability.
Food & Agricultural Grading
Optical sorting and grading for tea, spices, coconut, nuts, grains and fresh produce. Colour, NIR and hyperspectral vision remove stalks, foreign matter and defective product, and grade by colour and size.
PCB & Electronics Inspection
Automated optical inspection for electronics: solder paste inspection, pre and post-reflow AOI, through-hole and conformal coating checks. Find missing, wrong, misaligned and reversed parts and solder faults to IPC-A-610.
How We Work
We start from your product and your quality problem, and prove the measurement on your own samples before anything is built.
Vision System Design
Camera, lens and lighting chosen for your product and your defect, then proven on your own samples.
Fits Your Existing Line
Stations are added to the line you already run, with a pass or fail signal to your controls.
Records and Reporting
Every measurement is stored, so you have evidence per piece, per batch and per shift.
Cameras and Lenses Supplied
Hikrobot and Basler industrial cameras, lenses and barcode readers, sourced and supplied.
Software and Design Services
The software and mechanical design work that supports our vision systems, also available on its own.
Software Development
Dashboards, reporting and custom software, including the systems that sit behind a vision station.
Web and App Development
Web applications, e-commerce and mobile apps built with React, Next.js and modern stacks.
3D / CAD Design
Mechanical design for camera mounts, lighting brackets, enclosures and product development.
3D Printing
Functional prototypes, jigs, fixtures and enclosures printed in house.
Engineered and Supported in Sri Lanka
A vision system is only as good as the people who tune it. Ours is designed, installed and supported by a local engineering team, so changes to your products, standards or line are handled here, not through an overseas vendor.
Proven on Your Samples
We measure product your own team has already graded, so you can compare the two.
Built Around Your Line
Sized to your product, your speed and your buyer standards after a look at the plant.
Evidence You Can Show a Buyer
Stored results per piece and per batch, ready when a shade or a defect is questioned.
Registered Sri Lankan Engineering Company
