What do customers need?

Traditional inspection tools can’t get the full data and reach high precision when detecting large workpieces of machinery manufacturing. Handheld 3D laser scanner is user-friendly, easy carrying and can accurately obtain 3D data if we need to measure large volumes, workings with photogrammetry system will realize a better effect.

ScanTech 3D solution

ScanTech puts forward a 3D solution: simultaneously use handheld 3D laser scanner HSCAN and MSCAN photogrammetry system.

Metrological 3D scanner HSCAN can fast acquire 3D scanning data with 480,000 measures/s and reach 0.03mm accuracy.

The two 3D measuring devices will quickly acquire the full 3D data of large mining machinery equipment, shorten the work time and extremely enhance the scanning accuracy.

Time cost

  •  Attaching markers: 10 minutes
  •  Scanning: 20 minutes
  •  Detection report: 5 minutes

Scanning process

Step 1: MSCAN photogrammetry system to recognize markers

Although the 3D inspection of mining machinery equipment requires high data precision, ScanTech 3D solution can capture the complete and accurate 3D data in a short time by combining HSCAN 3D scanner and MSCAN. The self-developed software will realize contrast detection between scanned data and data model so as to get the color map. Machinery manufacturers will benefit from controlling cost and improve work efficiency.

ScanTech is always dedicated itself to research and develop 3D scanners for industrial 3D inspection. For large volume measuring, AXE 3D scanner enjoys unique advantages. It doubles scan area with only half markers and saves 50% work time, but still keeps the 3D data precise.
