Automotive Industry Laser Scanning

The global automotive industry continues to be one of the largest markets for metrology equipment and in particular hand-held laser scanning devices.

The passenger car segment dominates the automotive tool and die market due to the frequent introduction of new models and updates to existing models creating a consistent demand for dies, molds and tooling.

Exterior parts are manufactured worldwide for the automotive market and are crucial for the vehicle’s outer body. The growing innovation is encouraging suppliers to enhance manufacturing techniques.

Automotive mold and dies carries a large importance for the vehicle industry as produced parts have a prominent vehicle position and directly affect the car structure and are also fundamental to successfully assembly. It is conceivable how precise the automobile body structure parts must be.

Technological upgrades and enhanced production methodology remain highly crucial in the market. 3D scanning is a non-contact and non-destructive technology that digitally captures the shape of the objects and collect data on its shape. It also has a wide range of applications in other manufacturing industries producing products used in our daily lives.

But how does 3D scanning help automakers stand out in the highly competitive automotive manufacturing market?

The handheld 3D scanner has been favored by more and more enterprises in recent years due to the following features:

  • High-precision
  • Time-saving & labor-effective
  • Easy to operate

However, constrained by its working principles, handheld 3D scanner can’t overcome some deficiencies when confronted with large-scale objects:

  • Cumulative errors generated
  • Difficult to obtain small product details

This necessitates a need for an alternative measuring device (or something that has a photogrammetry system incorporated) to improve scanning accuracy, without increasing the budget and be time-consuming in operation.

The ScanTech 3D Solution

A versatile 3D scanner offering simultaneously the functions of normal handheld 3D scanner and a photogrammetry system. The Scantech KSCAN 3D scanner, a professional metrology-grade 3D scanner satisfies a wide range of scanning applications, and delivers on its extraordinary capabilities compared with normal handheld 3D scanners:

  • Built-in photogrammetry system: bring more convenience for scanning large workpieces; improve volumetric accuracy up to 0.035 mm/m
  • Dual laser scan mode – red and blue
  • Flexible measuring range: excellent performance on scanning both large and small objects
  • 650,000 measurement points acquisition rate under red laser scanning mode
  • Resolution up to 10μm

Case Study

  • Physical object: Commercial Vehicle Roof
  • Size: 3.5 m x 2.5 m

Four Steps To Obtain Accurate 3D Data

Step 1. Attaching markers and capture each of them via built-in photogrammetry system of the KSCAN 3D scanner.


Step 2. Quick scanning

Step 3. Get clean 3D point cloud data


Step 4. Data comparison between point cloud data and CAD model using 3D software ScanViewer to calculate data deviations and generation of inspection report.

The KSCAN 3D scanner performs precise large-scale measuring without the help of other measuring devices, reaching an accuracy of 0.020 mm and volumetric accuracy of 0.035 mm/m. This versatile 3D scanner greatly streamlines operation procedures and effectively tackles the difficulties for automakers.

KSCAN 3D scanner can be applied for reverse engineering, 3D printing, product development, 3D visualization, numerical simulation, etc.
