High-speed counting with Event-based Vision

Event Camera Vision Cam EB by Imago Technologies supports high-speed counting for transparent, low-contrast gel capsules 

Gel capsules falling from a vibratory feeder.  They are counted at high-speed by a line scan camera.

Processing with line scan technology:

Gel capsules cannot be recognized as an object by the software in the transmitted light process and therefore cannot be counted.

One capsule can appear as two objects.



Transparent, yellow capsules are to be counted at high-speed falling from a vibrating chute. Previous image processing solutions with a line scan camera using the transmitted light method reached their limits.

The gel capsules could not be counted at high speeds due to the transparency of the capsules and the lack of contrast caused by the yellow color.



The line scan camera with integrated real-time computer was replaced by the revolutionary event camera. Event-based image sensors record changes in a scene instead of capturing test objects line by line.

This means that Event-based algorithms can track objects even at very high speeds. The PSM module included in Metavision® Intelligence Software Suite was used as a starting point and fine-tuned to reach this solution.

Processing with event-based technology: Gel capsules can easily be recognized and counted.



IMAGO’s Event-based camera counts moving objects at a throughput of 1,000 objects per second. The technology can be used to count a wide range of products, giving many industries a new competitive edge.

The processing of the data takes place in the smart camera itself. There is no longer a need for expensive high-performance computers for ultrafast counting.
