Laser scanning technology plays an important role in the science and engineering arena. The aim of the scanning is usually to create a digital version of the object surface.
Multiple scanning is sometimes performed via numeroase cameras to obtain all slides of the scene under study.
Usually, optical tests are used to elucidate the power of laser scanning technology in the modern industry and in the research laboratories.
This book describes the recent contributions reported by laser scanning technology in different areas around the world.
The main topics of laser scanning described in this volume conÈ›ine full body scanning, traffic management, 3D survey process, bridge monitoring, tracking of scanning, human sensing, three-dimensional modelling, glacier monitoring and digitizing heritage monuments.

Safety Laser Scanner with Monitoring Case Switching on an S7-1500

An assembly cell with a robot has two workstations that can alternately be freely accessed by an operator. During operation, the situation changes due to the movement of the robot: The hazardous area becomes the working area and vice versa.

The following monitoring cases are defined:
Case 1: While the robot works at station 1,  the operator can load or unload at station 2.
Case 2: While the robot works at station 2,  the operator can load or unload at station 1.

To monitor this assembly cell, a SICK safety laser scanner S3000 is to be used in conjunction with a fail-safe SIMATIC S7-1500 (F-CPU).
The laser scanner monitors a danger area, depending on the robot’s position, and shuts down its safe OSSD output (Output Signal Switching Device) upon entering the protective field, which causes the F-CPU to shut down the robot.
