Data Encoding Formats
Prophesee’s event-based sensor are producing data in two different types of proprietary formats:
Those event formats have been designed to strike a balance between compactness and robustness, while taking into account constraints imposed by the processing platforms.
For an overview on event stream data formats, you can watch our training video.
Event Stream Data Formats
Event Stream Data formats are the most native formats for our event-based sensor, as they transmit the raw events detected by the pixels (timestamp, coordinates and polarity). The following schemes of encoding can be used:
The availability of the formats depends on the sensor:
Event Frame Data Formats
Those formats are producing frames of data made of arrays of values representing the number of pixels having spiked during an integration period or until reaching an event rate threshold.
Those formats accumulate event-data received during an integration period or until reaching an event rate threshold, and represent it in framed form. These formats enable avoiding the cost of decoding, pre-processing and formatting the event stream in software, and are therefore particularly useful for light-weight computing platforms.
The following formats are available:
