Prophesee, Event-based sensors - Real-time vision for real-time results

Prophesee, a key partner of Macnica ATD Europe, is reshaping the future of machine vision with its innovative Event-based technology.

 

Inspired by the way the human eye and brain work together, Prophesee’s solutions use a patented sensor design and advanced AI algorithms to capture and process visual information in a more efficient and intelligent way.

By mimicking biological vision, this technology reveals details that conventional frame-based systems simply cannot detect, opening up new possibilities for precision and performance in industrial applications.

What is an Event-based Sensor (EVS)?

Metavision sensor

 

 

 

Event-based sensors represent a major advancement over traditional image sensors. Instead of capturing static images at set intervals, these sensors detect and record changes in real time. This means they only respond to significant visual changes, providing a faster, more efficient way to process and analyze visual data.

 

This technology forms the backbone of Prophesee's Metavision, a system designed to leverage these sensors to deliver superior performance.

Understanding Metavision

Prophesee’s technology is powered by Metavision, a revolutionary concept that transforms machine vision by mimicking the way humans perceive motion and change. By using Event-based sensors, Metavision provides high-resolution, high-speed, and low-latency vision.

This breakthrough not only enhances the precision and speed of visual data processing but also unlocks new possibilities across a wide range of applications, from improving quality control to enabling predictive maintenance.

Key Industry Benefits

  • Boost Productivity: Achieve over 1,000 object counts per second and inspect items at speeds above 10 m/s, with 100 times less data to process
  • Unprecedented Quality Control: Lower reject rates with real-time feedback and advanced processing, featuring a 5 µs time resolution and blur-free asynchronous event output.
  • Predictive Maintenance: Identify early signs of machine failure by measuring vibration frequencies from Hz to kHz, reducing spare parts and downtime.
  • Monitoring + Safety: Enhance safety by monitoring worker and machine interactions in real time without capturing images, even in complex lighting.
  • Cut Complexity and Costs: Simplify processes by using the frameless, low data rate, high dynamic range sensor, eliminating the need for frame grabbers, industrial PCs, and custom lighting.

One sensor, Many applications

Safety: Object tracking

Prophesee’s event-based sensors excel at tracking moving objects within their field of view, leveraging their low data-rate and sparse information capabilities.

 

This approach allows for precise object tracking with minimal computational resources, eliminating traditional "blind spots" that occur between frame acquisitions. Additionally, the sensors offer native segmentation, focusing solely on movement while disregarding static backgrounds, enhancing overall tracking accuracy and efficiency.

Productivity: High-speed counting

With Prophesee’s technology, objects can be counted at unprecedented speeds with high accuracy and minimal motion blur.

 

The sensors independently trigger each pixel as objects pass through the field of view, achieving a throughput of over 1,000 objects per second and an accuracy of more than 99.5% at 1,000 objects per second. This capability ensures rapid, precise counting even in high-speed environments.

Predictive Maintenance: Vibration monitoring

Prophesee’s sensors offer continuous, remote vibration monitoring with pixel-level precision.

 

By tracking the temporal evolution of every pixel in the scene, they record each event's pixel coordinates, polarity of change, and exact timestamp. This detailed data enables a comprehensive understanding of vibration patterns across frequencies from 1Hz to the kHz range, providing valuable insights for predictive maintenance.

Quality: Particle/Object size monitoring

In high-speed production environments, Prophesee’s sensors allow for real-time control, counting, and measurement of particle or object sizes on channels or conveyors.

By capturing instantaneous quality statistics, the sensors ensure accurate process control with speeds up to 500,000 pixels per second and a counting precision of 99%, optimizing quality assurance in production lines.
