Chromasens 3DPIXA dual 200 µm HR employs factory-calibrated stereo cameras.

Chromasens extended its 3DPIXA family of high-performance 3D line scan cameras with a new model that provides a 55-inch FOV (field-of-view) for complete high-speed scans of large, complex and irregularly-shaped objects or textures to achieve accurate identification of defects in automobile manufacturing, food processing and in natural objects such as wood or ceramic tiles.

Poway, CA-based Chromasens’ newest camera, the 3DPIXA dual 200 µm HR employs factory-calibrated stereo cameras that enable the simultaneous acquisition of 2D color images along with either a height map or 3D point cloud. The 3DPIXA dual 200µm HR reduces overall operational costs by improving efficiencies in product validation. For example, it works in surface inspection of automobiles for cosmetic flaws like dings, dents and wrinkles in body panels, as well as for detection of functional flaws such as irregularities on the bearing surfaces of automotive rocker arms or the correct spacing and size of mounting holes on disk brake pads.

The 3DPIXA dual 200 µm HR can also verify the presence or absence of parts and the correctness of their shapes such as in the case of gears, which can have missing or malformed teeth. Finally, the camera can be used in assembly verification to insure error-free assembly, as is the case with closure panels that include doors, hoods, lift gates and tail gates, resulting in the automation and acceleration of production processes.

“The auto industry is characterized by highly automated mass production, strict quality requirements and a high degree of cost sensitivity,” said Jeremy Jowers, North American Sales Manager for Chromasens. “The new 3DPIXA dual 200 µm HR delivers savings to a variety of processes in the auto industry’s value chain, such as production, quality assurance and logistics, to achieve rapid and unambiguous detection of objects. It reduce scrap and the cost of manual inspection leading to a fast return on investment.”

Other key features of the 3DPIXA dual 200 µm HR are:
• 5940 mm/s maximum speed for image acquisition (19.48 ft/s)
• Height resolution up to 60 micron, range up to 400mm 
• 10 μm x 10 μm (10 μm pitch) pixel size 
• 7296 pixels per line (29.7 kHz line frequency) 
• Throughput up to 6.8 Gbit/s or 850 MB/s
