Data Encoding Formats

Prophesee’s event-based sensor are producing data in proprietary event stream formats (EVT that stands for EVent Type). Those event formats have been designed to strike a balance between compactness and robustness, while taking into account constraints imposed by the processing platforms.

The following schemes of encoding are used depending on the sensor and the EVK:

Gen3 sensors are using EVT 2.0 by default. Gen4 and IMX636 sensors are using EVT 3.0 by default and can use EVT 2.1 when embedded in EVK3 or EVK4.
