Five Applications for Intelligent Sensors in the Retail Industry: Part 3
2D LiDAR Sensors
2D and 3D Vision Sensors
As another option, 3D vision sensors work well for empty tote and level monitoring in the retail industry. SICK’s TriSpector1000 3D vision sensor is a configurable stand-alone sensor for this exact purpose. First, it records height profiles of moving totes with its laser line and puts them together as a high-resolution 3D image with intensity overlay.
Using configurable tools, the TriSpector1000 detects the position and alignment of totes. It also detects and measures the interior of the tote. It is also able to switch between different parameter sets via the trigger for fast adjustment to different tote types.
Empty tote monitoring done with ultrasonic sensors can also prove useful for retailers. The high measurement accuracy due to internal temperature compensation, the color-independent detection of optically challenging objects, and the immunity to dirt and dust all enable reliable operation, even under the most challenging conditions. Synchronization and multiplexing of several sensors ensure efficient area monitoring without the sensors experiencing mutual interference.
