Recommended Equipment

1. High-Resolution Industrial Microscope Camera

Recommended Model: DKP Medicam (or equivalent industrial microscope camera)

  • Resolution: 52MP or higher (ideal: 9000×6752 pixels)
  • Built-in LED Lighting: Bright, even illumination with adjustable intensity
  • Connection: HDMI/USB cable to connect directly to computer, monitor, or TV
  • Focus: Manual or auto-focus with sharp yarn visibility
2. Micro SD Card
  • Capacity: As per your need. 32GB will be sufficient.
  • Purpose: Store high-resolution images directly from the camera
3. Micro SD Card Reader
  • Type: USB 3.0 or higher for fast transfer
  • Purpose: Transfer images from Micro SD card to your computer
Software Requirement
OBS (Open Broadcaster Software)
  • Download: https://obsproject.com (Free & Open Source)
  • Purpose: Real-time preview of what the camera is capturing
  • Use Case: Connect camera via HDMI/USB → OBS displays live feed → ensures perfect focus, lighting, and framing before capturing
Note: Regular smartphone cameras are not recommended — they lack the resolution, magnification, and lighting control needed for reliable EPI/PPI analysis.
Pro Setup Tip: Use OBS in full-screen preview mode on a large monitor for precise alignment and focus adjustment.

Image Capturing Steps

1. Prepare Calibration Square
  • Print a 0.5 square inch calibration square in black color on white paper
  • Ensure edges are clean and unbroken (broken edges cause analysis failure)
  • Place on a flat surface
2. Capture Calibration Image
  • Position the square under the camera and adjust the distance so that the square occupies the maximum visible area without being cut off on any side
  • Ensure the square is properly aligned (not rotated)
  • The square must be clearly visible and in sharp focus
  • Capture the image of the square — it will be required along with the fabric image during upload
3. Capture Fabric Image
  • Use the same camera distance as the calibration image
  • Ensure the fabric is flat without wrinkles
  • Avoid shadows, reflections, or obstructions
  • Save in JPEG format (recommended) or PNG
Fabric Orientation Guidelines (Critical for Accuracy)

Best Practice: Always capture the fabric with warp and weft yarns aligned parallel to the image edges. This allows the system to process images faster and more accurately without needing orientation correction. You should uncheck the “Enable Orientation Correction” option to speed up image processing, provided you have captured the fabric image in proper orientation.

  • Do NOT rotate fabric more than ±45° — exceeding this will interchange the EPI and PPI results which is not recommended at all.
  • Never interchange warp and weft directions — this will interchange EPI/PPI results which is not recommended.
Orientation Correction Option
  • Use only if necessary: Select “Enable Orientation Correction” during upload if the fabric is rotated.
  • Warning: This can slightly slow down processing.

Special Rule for Twill Weaves:
Always position twill fabrics in correct orientation (warp/weft parallel to edges) and uncheck “Enable Orientation Correction”.
Reason: Few Twill weave patterns can confuse auto-rotation detection, leading to incorrect rotation of fabric and wrong EPI/PPI values.

Pro Tip: Keep your calibration image! You can reuse it for multiple fabric samples captured at the same distance.

Using SmartInspect Platform

Single Image Analysis
  1. Go to Upload page
  2. Upload your fabric image
  3. Upload your calibration image
  4. Click "Analyze"
  5. Wait around 30 seconds for results
  6. Review EPI/PPI results.
Batch Upload (Premium Only)
  1. Go to Batch Upload page
  2. Select multiple fabric images
  3. Upload one calibration image (applied to all)
  4. Analyze all images at once
  5. Review results individually
Additional Features
  • Count Calculation: Calculate average warp/weft yarn count
Note: This feature gives average yarn count. Results are valid only when you know in advance that warp and weft yarns are of the same type of fabric and same count.
  • Count Verification: Verify known yarn counts
How to review Results
  1. Visit the result page showing annotated image
  2. Check yarn orientation to make sure fabric is in proper orientation
  3. Look for any missed yarns where lines are not drawn
  4. Use the "Request Refund" option if results are clearly incorrect due to system error
Fail Alert: If it says "Failed" in result page and there is no annotated image, it means that EPI/PPI results were not reliable and system chose to not report the output.

When analysis may fail

Image Quality Issues
  • Out of Focus: Blurry images prevent yarn detection
  • Low Resolution: Images having very low resolution
  • Poor Lighting: Shadows, glare, or uneven illumination
  • Obstructions: Dirt, debris, or foreign objects on fabric
Calibration Problems
  • Broken Square Edges: Damaged or unclear calibration square
  • Distance Mismatch: Different distance between calibration and fabric images
  • Square Not Visible: Calibration square too small or unclear
Fabric Characteristics
  • Irregular Weave: Fabric belonging to exceptions for which our system is not designed. Check exception section for more details.
  • Textured Fabrics: Yarns are in wavy patterns
  • Textured Fabrics: Yarns are of significantly different thickness
Quality Assurance: SmartInspect is a tool to assist your quality control process, not replace it. Always review critical measurements.
