Example system: 3D shape recognition with a single camera

A simple and effective machine vision system for 3D capture and shape recognition.

How it works

As an example of our solutions in industrial machine vision, we show a 3D machine vision system with one camera and a rotary table.

The object is placed on the rotary table and captured from different perspectives as it turns. From the image data, the 3D geometry of the object can be captured and analysed. This makes it possible to determine, for example, its shape, dimensions and characteristic features.

Applications

The system can be used for a wide range of objects and applications, transparent objects included, and offers many possibilities for:

  • 3D shape recognition and measurement
  • Object identification and pose estimation
  • Quality control
  • Detection of shape deviations
  • Automated handling and positioning
  • Inspection of complex geometries

Modest hardware requirements

The approach stands out for its simple set-up with just one camera and a rotary table, and can be adapted and extended to suit the application.

The example shows how powerful 3D machine vision solutions for industrial applications can be realised with modest hardware requirements.
