3D HDR Imaging

Germany-based Automation Technology (AT) announced C4-2040-GigE comes with a resolution of 2048 x 1088 pixels and delivers more than 66 million 3D points with a profile frequency of up to 32 kHz. The camera is also available in its C4-2040-4M-GigE version, with a resolution of 2048 x 2048 pixels.

The 3D measurements come from active triangulation based on laser scanning:


The new 3D-sensor uses a global shutter and supports the HDR-3D technology allowing scanning materials and surfaces with inhomogeneous reflectivity properties. To cope with 3D HDR scenes up to 90db AT combines two approaches:

Multiple exposure (up to 3 exposures):


and non-destructive readout (up to 7 readouts) making possible to read out the recording of highly reflective objects shortly after the start of the exposure, the image of darker areas being read at the end of the integration time:


Thanks to TK for sending me the link!

  2. Cmosis produce imagers with those resolutions.
