Prophesee (“predicting and seeing where the action is”), based in France, uses its event-based cameras for AVs, Advanced Driver Assistance Systems (ADAS), industrial automation, consumer applications and healthcare.
Recogni’s solution is currently in trials at multiple automotive Tier 1 suppliers. Competitors using integer math are > 10X lower on this metric. The solution provides 1000 TOPS (trillion operations per second) with 6 ms latency and 25W power consumption (40 TOPS/W), which leads the industry. Anand, the range data is accurate to within 5% (at long ranges) and close to 2% (at shorter ranges). nighttime conditions RecogniĪccording to Mr. Anand, their machine learning implementation is so efficient that it can extrapolate depth estimates beyond the training ranges provided by the calibration LiDAR (which provides the ground truth to a range of 100 m).įigure 2: Recogni's perception stack trained on daytime data also performs under lower light level. Further efficiencies are realized by clustering weights optimally in the trained neural network.ĭuring the training phase, a commercial LiDAR is used as ground truth to train high resolution, high dynamic range stereo camera data to extract depth information and make it robust against misalignment and vibration effects. Recogni’s ASIC design is optimized for logarithmic math and uses addition. Minimizing off-chip storage and multiplication operations which are power intensive and create high latency.This network provides the perception and includes object classification & detection, semantic segmentation, lane detection, traffic signs and traffic light recognition

Proprietary machine learning algorithms to process millions of data points offline to create the trained neural network, which can then operate efficiently and learn continuously.These are fabricated on a TSMC 7 nm process, with a chip size of 100 mm², operating at a 1 GHz frequency. Custom-designed ASICs to process the data efficiently and produce accurate and high-resolution 3D maps of the car environment.Tesla expects FSD to eventually lead to autonomous vehicles (AVs), which provide complete autonomy in certain operational design domains with no human driver engagement required (also referred to as L4 autonomy). The trained network executes planning and control actions through an onboard, redundant architecture of purpose-built compute electronics.

~75K updates of the neural network have occurred over the past 12 months (~1 update every 7 minutes) as new data is continually collected and labeling errors or manoeuvering mistakes are detected. Camera (and other) data from these vehicles are used to train its neural network (which uses auto-labeling) to recognize objects, plot potential vehicle trajectories, select optimum ones and activate the appropriate control actions. A suite of 8 cameras on each vehicle provides a 360° occupancy map. Currently, this option is available on 160,000 vehicles purchased by customers in the U.S. FSD requires the human driver to be engaged in the driving task at all times (which is consistent with L2 autonomy).

During the company’s recent AI Day event, Elon Musk and his engineers provided an impressive presentation of its AI, data management and computing capabilities that support, amongst other initiatives, the Full Self Driving (FSD) feature on multiple Tesla models. Tesla TSLA is a dominant proponent of using passive camera-based computer vision to provide passenger vehicle autonomy. Transportation is one area that has benefitted significantly. Recent advances in deep learning and artificial intelligence have further accelerated the application of computer vision to provide real-time, low latency perception and cognition of the environment, enabling autonomy, safety and efficiency in various applications. It progressed dramatically in the next four decades as significant advances in semiconductor and computing technologies were made. Computer vision as an academic discipline took off in the 1960s, primarily at universities engaged in the emerging field of artificial intelligence (AI) and machine learning. With an increase in AoT™ (Autonomy of Things) in diverse applications ranging from transportation and agriculture to robotics and medicine, the role of cameras, computing and machine learning in providing human-like vision and cognition is becoming significant. It enables complex tasks and processes we take for granted. Vision is a powerful human sensory input.
