  • Operation possible even with supply voltages from 9 V DC

  • 4-layer laser scanner technology provides reliable, trouble-free detection of objects, even on a slope

  • Easy sensor integration due to compact design

  • Lower power consumption reduces costs

  • Real-time output of measurement data

  • IP 69K-rated housing provides accurate measurements in all weather conditions

4-layer technology

The LD-MRS scans four scanning layers simultaneously. Combining the data from several scanning layers allows, for example, the pitching movements of vehicles or sloping lanes to be detected – the reliable detection of objects is thus always guaranteed. As a result of the 4-layer technology, measurements of the ground can also be differentiated from measurement on objects. The result is a reliable and trouble-free use of the LD-MRS.

Collision avoidance for trains and trams with the help of Long range SICK LD-MRS laser scanners

Long range SICK LD-LMRS or IBEO laser scanners with multi echo can help in context perception in front of the TRAM or train.  The laser scanner can detect the true nature of the RISK by combining the the contextual data given by a GPS with the object level information given by the laserscanner and generating or forcing the required action for example applying brakes or firing an alarm.


The object classification by the laserscanner can be done using Kalman filter by detecting the current position of the object and predicting where the object can be.  The profiling of the object is performed by the object outlines.  The object classification and context analysis helps in calculating the risk assessment and the system can be designed to take action accordingly.


The SICK LD-MRS laserscanner can scan an area of around 100° in front of the train or tram and also gives 3.2° vertical field of view through its multi-layer (up to four layers or 8 layers) technology. The laserscanner can detect objects up to 200m.  It has a distance resolution of 4cm and horizontal angular resolution of 0.125°.

Ibeo LUX Laserscanner Vs SICK LD-LMRS Laserscanner

In the longrange multiecho categories IBEO and SICK provide ltheir own laserscanners which have the same features and characteristics.  We carry all range of SICK LD-MRS laserscanners and so wanted to see if there are any differences between the two.  In this blog post we will do a model comparison of both brands.

  IBEO miniLUX


This shows that the SICK LD-MRS series laserscanner with S01 extension correspond with the IBEO laserscanners.  While IBEO has one more laser scanner the IBEO miniLUX.  In future blog posts we will be writing more about the potential uses for autonomous robotics of the SICK LD-MRS laser scanner with built in object tracking features.  This feature is especially helpful for the autnomous cars applications.
