VRmagic Imaging will present the LineScan3D at booth 2352, a 3D sensor with a field of view of 74mm width and 76mm height at a sub-pixel resolution in the area of 1.5μm. This version of the GigE-Vision compatible 3D sensor is especially fitted for automatic optical inspection of printed circuit boards.

With an integrated laser, optics, protective circuitry and a GigE-Vision interface, the LineScan3D is housed in robust IP65/67 aluminium, has a 24V power supply and an isolated RS485 interface for ABZ rotary encoder input and trigger. Multi-sensor setups can also be realised without additional hardware with the LineScan3D.

Real time extraction of the laser line is carried out in the FPGA of the sensor at 1,000Hz and with an area of interest of 360 lines and 2,048 points per profile. The extraction algorithm is configurable and can be adapted to suit particular applications. An optional high dynamic range (HDR) mode further enhances the laser line extraction for materials with varying surface reflectivity characteristics.

In addition to the 3D range map, the sensor also supplies the brightness values of the laser line, the so-called intensity image. This grey value image enables efficient 2D image processing in parallel to the 3D measurement, e.g. for surface inspection or object identification via bar codes. The extracted 3D profiles and 2D image data are recorded at the same time and from exactly the same perspective – this provides optimum preconditions for combined evaluation.
