Pixy 2.1 Smart Vision Sensor-Object Tracking Camera

Recently Pixy has upgraded their Pixy 2.1 Smart Vision Sensor camera from 2.0 to 2.1. An improved Pixy version 2.1. loaded with below up-gradation: Wider field-of-view — the previous Pixy version (2.0) had a 60-degree horizontal field-of-view. The new version has an 80-degree field of view. Most users want the larger field of view because of the ability to see more of the environment per image. There is some spherical distortion with the new lens, which comes with a wider field of view.

Replaceable lens — the M12 lens mount allows you to substitute a different lens if you wish

Adjustable focus — the M12 lens has an adjustable focus that allows focusing on objects at practically any distance, including as close as 0.25”.

Less chromatic distortion — the new lens has virtually no chromatic distortion at the edges, whereas the previous Pixy version had a small amount of chromatic distortion.

Less pixel noise — the new lens has an F-stop of 2.0 vs the previous lens which had an F-stop of over 3.0. This means better light gathering ability, more signal and less noise for a given amount of ambient light. Less noise means better detection accuracy for this new Pixy version. Image sensor: Aptina MT9M114, 1296×976 resolution with integrated image flow processor

Everything else about Pixy 2.1 is the same — software, firmware  and feature set. Pixy 2.1 is slightly larger, however, adding 0.25 inches to the height and depth of the camera versus Pixy 2.0.

The new algorithms can detect intersections and “road signs” as well. The road signs can tell your robot what to do, such as turn left, turn right, slow down, etc. And Pixy2 does all of this at 60 frames-per-second, so your robot can be fast, too.
