ZED 2 Depth Camera

ZED 2: a new stereo vision technology

The ZED 2 camera offers greater depth detection with a 120° wide-angle field of view. The aim here is to combine depth-of-field detection (up to 20 m) with object detection, in particular human beings in movement.

The stereoscopic camera uses two high-resolution sensors to detect vehicles and objects. It can therefore combine different view points, with the help of an IMU and efficient motion sensors, to perform multiple operations:

• Simultaneous localisation and mapping
• Floor plane detection
• Skeleton tracking

The camera can be managed remotely using a dedicated cloud platform to control streaming, collection and analysis of 3D data and to run applications.

An assistant for maintaining social distancing

The ZED 2 camera sets itself apart by allowing you to simply run a robot vision application for the purposes of social distancing.

The camera can track individuals to measure the distances between different people in a given place. You can then program a loudspeaker to be triggered to remind people of the health regulations.
