Linescan camera with 3D stereo inspects complex objects for defects
31 January 2025 
The German machine vision specialist Chromasens has announced an industrial camera that merges linescan imaging technology with fast 3D stereo computation to tackle inspection and measuring challenges that arise when scanning large, complex or irregularly-shaped objects for flaws.
The 3DPIXA pro dual camera boasts 29.7kHz line rate speeds, an optical resolution of 200µm/pixel, and a 1.4m field-of-view. It can simultaneously capture 2D colour images and height maps or 3D point clouds for “unmatched” quality inspection capabilities. The camera can also detect overlapped or non-aligned parts, displaying different colours on a depth map based on height differences.
The camera is claimed to cut operational costs by improving efficiencies in product validation. For example, in automotive manufacturing, it can enhance surface inspection of large body panels for cosmetic flaws such as dents and wrinkles, or detect flaws such as irregularities on bearing surfaces, or the correct spacing and size of mounting holes on disk brake pads. This reduces scrap and cuts the cost of manual inspections, leading to faster ROIs.
The camera simplifies the process of configuring 3D systems with support for libraries from Halcon (MVTec), MIL (Matrox), LabView (National Instruments), and Coake (SAC), as well as Chromasens’ own 3D-API. The IP50-protected camera measures 220.3 x 463 x 98.5mm.
Imaging performance is enhanced by an advanced trilinear CCD line RGB sensor with 10 x 10μm pixels, and a Camera Link interface.
