TIME-OF-FLIGHT CAMERA FOR AUTOMATION TECHNOLOGY

3D view of intralogistics processes 

A 3D camera expands the options offered by sensor systems in intralogistics by another dimension. This allows the camera to offer precise real-time capture of fill levels or a comprehensive view of the process. In addition, it can also be used as the ‘eye’ of IIoT applications, allowing it to determine KPIs such as ‘Overall Equipment Efficiency’ (OEE).
