Chromasens

The Chromasens 3DPIXA camera is based on the stereo principle, whereas two images are captured from the same object. Height data is calculated from these two images in real time with advanced pattern matching algorithms running on GPUs. This innovative merging of line scan technology and ultra-fast 3D stereo algorithms opens up the potential for new machine vision applications that demand precise and fast 2D and 3D measurements. The 3DPIXA stereo camera simultaneously provides color images alongside either the height map or 3D point cloud.

Included with the camera is easy-to-integrate CS-3D-API software that makes 2D images and 3D data available. Integration of CS-3D-API in machine vision libraries is an ongoing process for Chromasens and support for the most commonly used libraries will be available soon. To date, the CS-3D-API is available in National Instruments LabView software and Coake 7 from SAC.

Line scan technology is ideal for fast moving objects because it provides both high speed and high resolution images. Simultaneous capturing of 2D images and 3D height maps opens up combined 2D and 3D image processing. Optical resolution up to 5 micron delivers unprecedented height resolutions up to 1 micron, opening up new 3D inspection applications that could not be attempted in the past due to resolution and speed limitations. Because the 3D-PIXA applies the stereo approach to capturing images, it allows for illuminations that are optimal for the nature of the object surfaces. This is crucial because high precision and robust results depend on an evenly illuminated surface. The Chromasens Corona series is ideal for this type of application since it provides different kinds of high intensity illuminations suitable for the 3DPIXA stereo camera.

Applications include high precision inspection of metallic surfaces e.g. for the medical and automotive sectors, inspection of printed circuit boards and measuring of solder joints and connectors. The high resolution allows for capturing of small structures and connectors in the microelectronics and semiconductors sector. Inspection of color and shape of pharmaceutical and natural products are applications making use of the combination of color and 3D.
