human retina, each pixel of the Metavision sensor embeds its own intelligence and activates themselves independently, triggering events. Prophesee has also partnered with Sony
Semiconductor Solutions to integrate the Prophesee advantages with a new generation stacked, event-based vision sensor, co-developed with Sony. Prophesee has released two evaluation kits that give developers early access to the sensor, which features 4.86µm pixel pitch and 1,280 x 720 pixel resolution. Key to implementing the Prophesee
solution is the Metavision Intelligence Software Suite. It can be used to perform a variety of design exploration steps and incorporate customised software to meet specific market requirements.
Use cases for the two sensors include
high-speed counting, vibration monitoring, object tracking, particle size monitoring and other critical, vision-enabled processes in manufacturing, assembly, logistics, quality control and inspection. As one example, the platform can be used to improve predictive maintenance by measuring and monitoring equipment vibrations from 1Hz to 10kHz remotely, continuously and in real time under normal lighting conditions. In automotive and mobility, DTS from
Xperi has used the sensor to develop a neuromorphic driver monitoring solution, registering saccadic eye movement and micro-expressions. In addition, VoxelFlow, developed by Terranet in conjunction with Mercedes-Benz, uses Metavision to enhance existing radar, lidar and camera
systems for autonomous driving. Another outstanding application of
neuromorphic event-based vision can be witnessed in the study conducted by Gensight Biologics. Te study, published in
‘The Metavision Intelligence Software Suite can be used to improve predictive maintenance’
Nature Medicine, is the first case reported of partial recovery of visual function in a blind patient with late-stage retinitis pigmentosa. Te patient is the subject of the ongoing trial of GenSight Biologics’ GS030 optogenetic therapy. Te study combines gene therapy with a light-stimulating medical device in the form of goggles that uses Prophesee’s Metavision sensing technologies.
Zeiss AICell trace – a revolutionary generation of inline measurement technology
By Manuel Schmid, Carl Zeiss Automated Inspection
Te new generation of inline measuring technology, Zeiss AICell trace, forms the basis for the Zeiss strategy, ‘Metrology goes inline’. It provides improved quality assurance in the automotive sector with regard to productivity, efficiency and economic sustainability. Previously, it was mainly only process
control that was carried out on the production line. Now, Zeiss’ inline measuring system opens up real traceable metrology tasks in accordance with DIN- standards directly on the production line
‘By using this new technology, absolute inline measurement results can be achieved’
which, in the past, were only possible with CMMs in dedicated measurement rooms. By bundling process control and inline
metrology in one single cell, Zeiss AICell trace opens up new possibilities for customers when defining quality assurance strategies. Te system provides high- precision digital quality information through point cloud-based feature detection in real time. Te system contains the following components: fixed floor markers with integrated LEDs that act as a temperature-

independent reference in the coordinate system; tracking cameras that capture both the exact position of the sensors in each measurement position, as well as their own position; and the Carbon Fiber Navigation Tool with integrated active LEDs which forms a fixed unit with the 3D point cloud sensor, AIMax Cloud. By using this new optical tracking
technology in combination with the AIMax Cloud sensor, absolute inline measurement results can be achieved that were previously not possible on car body construction lines. Tis opens up the potential for cost
saving and process optimisation, thanks to the ability to carry out traceable inline measurements in the production environment. Te automotive industry is

currently going through a radical change, with the shift from the combustion engine to e-mobility, as well as an increase in efficiency in factories and the digital transformation of production plants. To implement these changes as quickly
as possible, the original equipment manufacturers have set up various strategy programmes, some incorporating the new Zeiss inline metrology solution. Zeiss has already implemented this inline measurement technology several times at stations with individual components, sub- assemblies and for complete car bodies for customers in the body shop. Zeiss is also working with Gom to integrate
digital inline metrology products into the production lines of car body shops. O
