List of robotic vision sensors and image libraries

A 2D vision sensor or an ordinary camera delivers 2D image frames of the surroundings, whereas a 3D vision sensor delivers 2D image frames and an additional parameter called the depth of each image point. We can find the x, y, and z distance of each point from the 3D sensor with respect to the sensor's axis.

There are quite a few vision sensors available on the market. Some of the 2D and 3D vision sensors that can be used in our robot are mentioned in this chapter.

Pixy2/CMUcam5

The following picture shows the latest 2D vision sensor, called Pixy2/CMUcam5 (https://pixycam.com/pixy-cmucam5/), which is able to detect color objects with high speed and accuracy, and can be...
