Metavision® sensor is first mass production chip to allow commercial-scale adoption of breakthrough machine vision technology in Industry 4.0 and Industrial IoT
Prophesee inventor of the most advanced neuromorphic vision systems has introduced the first industry-standard packaged chip that leverages Event-Based Vision technology, a significant advancement over traditional frame-based vision approaches.
Under development for the past five years and commercially tested by several customers, this third generation version houses a Prophesee-enabled VGA-resolution sensor and represents the industry’s first implementation of Event-Based Vision technology in a commercially-viable, industry standard package.
This new packaged version of Prophesee’s Metavision® sensor is aimed at developers of cameras to enable next-generation vision in industrial automation and IoT systems such as robots, inspection equipment, monitoring and surveillance devices.
It leverages Prophesee’s use of neuromorphic vision technology to offer highly-efficient machine vision capabilities for a variety of use models, two including ultra high-speed part counting, vibration measurement and monitoring or kinematic monitoring for predictive maintenance. It allows for unprecedented speed, dynamic range, data volume, and power efficiency.
“This is a major milestone for Prophesee and underscores the progress in commercialising our pioneering Event-Based Vision sensing technology,” said Luca Verre, co-founder and CEO of Prophesee.
“After several years of testing and prototyping, we can now offer product developers an off-the-shelf means to take advantage of the benefits of our machine vision inventions that move the industry out of the traditional frame-based paradigm for image capture.”
In Prophesee Metavision® sensors, each pixel is independent and asynchronous. Each pixel only activates itself if it senses a change in the scene, a movement – an event.
This proprietary Event-based approach allows for major reductions of power, latency and data processing requirements imposed by traditional frame-based systems. It enables sensors to achieve much higher dynamic ranges than commonly associated with highspeed vision. And it allows cost-efficient sensors and systems to record events that would otherwise require conventional cameras to run at 10,000 images/second and more.
The sensor can be used by system developers to improve and in some cases create whole new industrial uses, including accelerating quality assessment on production lines; positioning, sensing and movement guidance for robots to enable better human collaboration; and equipment monitoring (e.g. caused by vibration, kinetic deviations) making the system an asset for predictive maintenance and reduced machine downtime.
The sensor is supported by a robust development environment that includes a comprehensive software development kit (SDK), a full set of drivers, the Prophesee Player tool for recording sequences and visualizing data and access to the Prophesee Online Portal, a detailed knowledge centre containing useful resources for developers.
The chip, available in a 13×15 mm mini PBGA package, integrates Prophesee’s third generation CMOS Image Sensor (CIS) vision module. It features 640 x 480-pixel resolution with 15 μm pixels in a 3/4” optical format. It is manufactured in a .18 micron specialized CIS process. The packaging was realised by Kingpak, an expert in CMOS Image Sensor (CIS) micro packaging.
