Ubicept final month launched the Ubicept Toolkit, which it mentioned brings physics-based imaging to fashionable laptop imaginative and prescient methods. The corporate claimed that its method delivers high-quality, reliable knowledge.
The toolkit permits offline and reside processing of complementary metal-oxide-semiconductor (CMOS) movies and single-photon avalanche diode (SPAD) cameras, aiding in object recognition and spatial consciousness. Ubicept asserted that its SPAD sensors provide superior low-light and high-contrast imaging as compared with typical cameras.
Industrial cameras in use for the previous 4 a long time have used CMOS sensors. That is additionally the identical know-how utilized in digital pictures cameras and safety cameras, so their manufacturing quantity makes CMOS sensors comparatively low cost.
The issue with CMOS cameras is that low-light photographs may be noisy, and movies captured with a CMOS sensor are blurry when a single body.
The invention: higher low-light decision
Ubicept mentioned its novel method is to make use of SPAD sensors with a brand new image-processing pipeline to enhance the distinction and readability of the ensuing photographs and/or movies. This additionally presents quick picture high quality enhancements with present CMOS {hardware}, in response to the Boston-based firm.
For imaginative and prescient notion functions in low-light conditions, corresponding to autonomous driving at evening, Ubicept mentioned it system can successfully enhance a number of edge-case eventualities that confuse present camera-based navigation and notion pipelines.
The SPAD know-how, which captures every photon with sub-nanosecond decision, can improve picture high quality in numerous environments, the corporate claimed.
Ubicept plans to combine its software program with present {hardware}, corresponding to Qualcomm Snapdragon and NXP chips, to enhance notion fashions in robotics and automotive functions. The know-how is predicted to mature and turn out to be extra inexpensive inside the subsequent one to 2 years.

“Ubicept’s know-how revolutionizes how machines see the world by unlocking the total potential of as we speak’s and tomorrow’s picture sensors,” said Sebastian Bauer, CEO of Ubicept. “Our physics-based method captures the total complexity of movement, even in low-light or high-dynamic-range circumstances, offering extra reliable knowledge than AI-based video enhancement.”
“With the Ubicept Toolkit, we’re now making our superior single-photon imaging extra accessible for a broad vary of functions from robotics to automotive to industrial sensing,” he added.
{Hardware} versus software program
When ask concerning the product roadmap, Bauer replied, “What we’ve launched is a chunk of software program that folks can run with the GUI [graphical user interface], but in addition it has an API [application programming interface]. And what it does is you are able to do offline processing of present CMOS movies.”
“You may as well hook up CMOS cameras reside and have reside processed outputs,” he mentioned. “You possibly can join your laptop to a SPAD digicam and actually see the standard distinction with our imaging, consider the standard of enhance enchancment of CMOS versus SPAD, and construct your individual laptop imaginative and prescient utility.”
Ubicept mentioned its system is designed for probably the most superior sensors to maximise picture knowledge high quality and reliability. It famous that the Ubicept Toolkit can help any extensively accessible CMOS digicam with uncooked uncompressed output, giving notion builders quick high quality positive factors.
The corporate mentioned it needs to work with robotics builders and digicam producers to develop a brand new technology of good notion.
“We’re not planning on making sensors ourselves, however we have now actually good IP [intellectual property] for 3D stacked sensors, which means doing a little processing straight on the sensor chip, after which basically all the way in which as much as the notion,” mentioned Bauer. “If you concentrate on cameras, you may have a digicam that’s a sensor, plus an ISP or picture sign processing chip, after which you may have a notion mannequin.”
“Our considering is to to construct all that full stack, together with a full-blown ISP/processing pipeline by utilizing bodily optimum single full-term notion and changing that into into high-quality notion output, like object detection, simultaneous localization and mapping [SLAM], visible odometry,” he defined.
Ubicept companions with Pi Imaging Expertise
Pi Imaging Expertise is a pacesetter within the subject with its SPAD Alpha, a next-generation 1-megapixel digicam that it mentioned delivers zero learn noise, nanosecond-level publicity management, and body charges as much as 73,000 fps. Designed for demanding scientific functions, the digicam presents researchers and builders excessive temporal precision and lightweight sensitivity.
The businesses mentioned the Ubicept Toolkit builds on these strengths by remodeling the SPAD Alpha’s uncooked photon knowledge into clear, ready-to-use imagery for notion and evaluation.
“Ubicept shares our deep dedication to advancing notion know-how,” mentioned Michel Antolović, CEO of Pi Imaging Expertise. “By combining our SPAD Alpha’s state-of-the-art {hardware} with Ubicept’s real-time processing, notion engineers can get probably the most from what single-photon imaging has to supply.”
Ubicept mentioned its toolkit supplies engineering groups with all the things they should visualize, seize, and course of video knowledge effectively with the Ubicept Photon Fusion (UPF) algorithm. The SPAD Toolkit additionally contains Ubicept’s FLARE (Versatile Mild Acquisition and Illustration Engine) firmware for optimized photon seize.
As well as, the Ubicept Toolkit comes with “white-glove help to early adopters for a extremely customized and premium expertise,” mentioned the corporate.
