Fraunhofer eye tracker – a calibration-free solution with scalable and configurable Hough IP Core Prof. Peter Husar, Dr Frank Klefenz Fraunhofer-Institut für Digitale Medientechnologie (IDMT), Ernst-Abbe- Zentrum (EAZ)


Eye tracking for machine vision is a very demanding task regarding accuracy and speed. A positioning error of the pupil of less than 1mm is required and capturing fast saccades at 1,000fps is necessary. Nowadays, eye trackers are proprietary, expensive and cumbersome to use as they require a tedious calibration procedure before image processing. The new eye tracker solution


from


Fraunhofer IDMT with a scalable and configurable Hough


IP core overcomes all these obstacles. There is no calibration step necessary. Depending on the limited image size, the eye tracker can process frame rates of more than 1,000fps and fulfils all requirements regarding the positioning error. www.idmt.fraunhofer.de


Brain-inspired machine vision Frans Kanters Inviso


Inviso’s ImageBoost is a novel image processing platform inspired by the human visual


system. The human visual system is very robust and capable of handling a wide variety of lighting conditions. One important reason for this is its use of contextual information from the image at a low level. At the Eindhoven University of Technology,


the orientation-sensitive cells of the primary visual cortex are mathematically modelled, and this model is implemented by Inviso on an FPGA, resulting in the Inviso ImageBoost platform. This platform can be used in a wide variety of applications, delivering high speed and accurate detection under hard lighting conditions. Some examples include crack detection in natural stone slabs, line enhancement and quantification of fibre alignment in medical imaging, distance measuring between semi-transparent sheets and ball detection for soccer robots. www.inviso.eu

AOI light application consists of three LED arrays, which have different colours and radiation angles. This structure can map the slant surface shape of the components, with different colours representing different slant surfaces. The system can therefore judge the situation of the slant surface by the colour reflection. The AOI illumination system can be the


basis of various types of defect detection, for example, salient point, pits, and scratches, all of which are more difficult to detect under standard illumination. The lighting system is ideal for PCB inspection, such as PCB assembly inspection in surface mounting technology, especially for detecting defects of solder joints, and inspection of the pins of ball grid arrays, a type of IC packaging. www.optmv.com


Native WDR: a radical, innovative breakthrough in CMOS sensors based on the Magic technology Yang Ni, Nicolas Baroan New Imaging Technologies (NIT)


New Imaging Technologies (NIT) offers CMOS imaging sensors based upon a unique and patented pixel technology, which provides intrinsic high dynamic range response of more than 120dB, no noticeable fixed pattern noise, and operability without image artefacts to more than 90°C. NIT’s Native WDR (Native Wide Dynamic


Range) sensors are based on a new generation of CMOS imaging technology named Magic (Matrice Active à Génération d’Image indexée sur Contraste), capable of generating a highly stable image even under very wide intra-scene dynamic range (>120dB). This is in a single frame time and without multi-exposure, any setting of knee points or external control. NIT offers a complete range of standard, customised and full custom CMOS imaging sensors for a variety of applications where performance, cost, quality and reliability are key requirements. www.new-imaging-technologies.com
