that can be achieved with modern 3D sensing technology, in addition to the price point that it is coming down to, [it] gives the potential to open up massive opportunities in the food [retail] industry. ‘Looking at the new Amazon supermarkets,
The Intel Realsense D400 offers 3D stereovision at a reduced price thanks to a powerful, mass-produced ASIC chip designed for consumer electronics
a future in retail is the Intel Realsense D400, which comprises a pair of stereo infrared cameras combined with a pattern projector and an additional RGB camera. Released in January, the D400 – through its use of low-cost ASIC technology – is available at £170 as a house product and below £100 at the module level, making it much more suitable for retailers looking to deploy the technology in multiple instances. ‘With the D400 Intel are looking to get
the price point down, enabling it to be very disruptive and have applications everywhere,’ Williamson commented. ‘Te camera delivers 3D data in full HD at up to 90fps. A lower cost rolling shutter version is also available, along with a higher cost global shutter version for fast-moving objects.’ Tese cameras could all be very significant in the retail sector, according to Williamson, especially for producing rapid results when identifying what products are being picked off a shelf. ‘Te Realsense D400 could play a big role
in the food [retail] industry and is a major step up from any stereovision technology in the past,’ said Williamson. ‘While time-of- flight technology could achieve similar depth sensing results, its price point is currently in the thousands. In a controlled environment Realsense gives you excellent results at fraction of the price, which is the main factor for supermarkets looking to purchase multiple systems. It’s a product that touches the old machine vision world and the new embedded machine vision world.’ ‘I think that this could be very interesting for
retail, going forward,’ Williamson continued. ‘I’m aware of a lot of research departments within supermarkets that are exploring this sort of technology. Tey’ve started off by trialling more automated checkouts and hand-held scanners, but they need to investigate in a different way to work out the best options for automating their retail experience. ‘I think that with the high level of quality

for example, if a Realsense camera was used every three metres along the aisles to see when customers pick items up, with an additional embedded board each system could be built for around $500. At these price points this use of [3D] vision in retail suddenly becomes a lot more viable.’ In regard to how the introduction of cashier-
less supermarkets could impact the machine vision market, Fischer concluded: ‘We will see that the machine vision market will adopt the technology which is nowadays already being used in the retail market – this is embedded vision technology, where you enable customers to design very cost-effective systems and lean solutions by utilising technology like ARM- based processing capabilities and consumer- driven interfaces like MIPI.’ O
VISION TO ID CHECK SHOPPERS
Retailers in the US and UK are expected to trial an age verification vision system at checkouts for customers buying age- restricted items. NCR, a technology firm specialising in financial transaction hardware, has integrated a camera-based age verification platform that uses facial recognition software into its self-checkout system. The US and UK retailers will trial the solution in the coming months.
The self-checkout’s built-in camera system, with age detection technology from Yoti, can estimate a customer’s age and flag any customers determined to be under the required age limit for a product. This threshold is configurable by the retailer and is generally ten years above the legal limit. ‘Waiting for age approval at self-checkouts is a source of frustration for many shoppers, who just want to get home as quickly as possible,’ said Robin Tombs, CEO and co-founder of Yoti, a company offering digital solutions for proving identity. ‘Our integration with NCR delivers a frictionless and innovative way for customers to prove their age in seconds. It’s a simple process that helps retailers meet the requirements of regulators worldwide. Customers will spend less time at the self-checkout, and employees can assist with other tasks, improving the overall shopping experience.’
