2 Smart Sensor
2.1 Functions
The O3M151 Smart Sensor is an optical system which measures the distance between the sensor and
the next surface� An additional illumination unit illuminates the scene and the sensor process the light
reflected by the surface�
The Smart Sensor is optimised and matched to requirements and needs on mobile driven machines� It is
intended for use in outdoors and for difficult ambient light situations�
The principle is based on PMD technology for outputting 3D image data� In addition to new options for
vehicle automation (AGV, automated guided vehicle), it also provides new assistance functions for auto-
mation tasks�
Communication is possible via Ethernet or CAN� System parametrisation and monitoring of the 3D data
arecarriedoutviatheifmVisionAssistant.→ Ifm Vision Assistant programming manual
The pre-processed functional data are output via the CAN bus, with via CANopen or SAE J 1939�
→Chapter"7 Interface" on Page 20
The Basic Function with functions such as measurement of minimum, maximum and average distance
are available for simple distance tasks�
The Object Detection function provides for automatic object detection of up to 20 objects� This function
can, for example, be used as a collision warning�

O3M151 3D Smart Sensor Basic Function

2.2 Measuring principle
The device measures according to the light runtime method based on a phase measurement with modu-
lated light�
Based on this principle, the following points must be taken into account during the measurements:
●Clean sensor window
– Cleanliness is a basis for the reliable operation of optical sensors� Dirt or liquids reduce the light
transmission and cause light scatter� This effect can affect the resolution and the measuring range
of the sensor system�
– Water droplets on the sensor glass can lead to unclear detection of the scene� The objects are de-
tected as larger than they are in reality�
►Installation in areas of the system which become heavily soiled must be avoided�
►Keep sensor window clean�
●Illumination/Range
– The measurement of objects is carried out based on the active illumination by the additional illumi-
nation unit� The emitted infrared light makes the sensor virtually independent of the ambient lighting
conditions� In case of bright sunlight, restrictions in the system range can result due to increased
signal noise�
– The measurement range is dependent on the reflectivity of the object to be detected�
– Due to the optical measuring principle the system performance can be considerably increased by
using reflective materials (Factor 3)�
●Clear in immediate vicinity
– Objects in the immediate vicinity (1 m distance) can falsify the measured values of the sensor�
– The wall on which the sensor is mounted should not be within the sensor area�
►Keep the illuminated area of the illumination unit in the immediate vicinity (up to 50 cm) of attached
parts clear�

2.3 Operating check
With an optical system, detection faults can occur in case of poor visibility (e�g� under very dense fog, a
great deal of dust, very heavy snowfall, etc�)� The O3M151 Smart Sensor is equipped with sensory fault
detection in the system and generates a message when faults occur�
●the "Blockage Detection" function actively detects relevant soiling, condensation on or icing-up of the
sensor;
(This function is not yet available with the SW Version OD 2�2�4 and OD 2�2�5� It will be possible to
activate this function later in a firmware update�)
●The "Diffuse Scene" function actively detects diffuse faults, such as dense fog or clouds of dust in the
sensor area�
Internal diagnosis of the hardware for faults → Operating instructions
●Application-specific solutions can result simply and especially conveniently with a controller (e�g�
CR040X) or display (e�g CR108X) based on the functional output�
There are special CODESYS libraries for receiving and interpreting the CAN signals of the O3M151
Smart Sensor� In addition, various application examples on a CODESYS basis are also available�

3 Object Detection
3.1 Functions
Object detection
Reflector tracking
Collision prediction
Do not attach sensor at a height of under 50 cm�
Object detection
3D data are used via a CAN interface for object detection�
Up to 20 independent objects are detected and tracked from the measured distance values� A broad
range of information is available for each object:
●Position and orientation in the space (x, y, z)
●Size of the object
●Relative speed of the object
●Qualitative evaluation (quality) of this information
Reflector detection
Reflectors can be used for marking and individual tracking of interesting objects� These are detected
separately and with a greater range� Depending on the reflectivity, it is possible, for example, to use warn-
ing vests as reflectors�
Collision prediction
The Smart Sensor can predict potential collisions very accurately by evaluating the vehicle's own speed
and its yaw rate�
This function offers a major advantage compared to collision warnings based purely on a distance meas-
urement� In addition, the speed and direction of the own vehicle and objects are also taken into account�
(This function is not yet available with the SW Version OD 2�2�4 and OD 2�2�5� It will be possible to acti-
vate this function later in a firmware update�)
3.2 Possible applications
●Area monitoring with static attachment and with attachment to a vehicle (from several user-definable
areas simultaneously)
●Marking, identification and specific tracking of reflected objects
●Vehicle automation (AGV: automated guided vehicle)
●Collision prediction

5 Application examples
5.1 Area monitoring
5.1.1 Introduction
With static attachment and with attachment on a vehicle, the Object Detection function enables area
monitoring of several user-defined areas simultaneously�
Functions:
●Monitoring of an area in front of a door or access point
●Control and/or signalling of opening via the controller based on the CAN sensor signals�
●Attachment to a vehicle and monitoring of areas in the driving path
●Selective distinction between normal and reflective objects
●Evaluation of the presence of the object in the sensor's field of vision
●Filtering of the objects by size and speed
●Monitoring of access to tunnel boring machines or to other accessible machines
When using an ifm controller or display, the included CODESYS module can be used to receive and inter-
pret the CAN signals� CODESYS program examples of various applications are available in the Download
area�
→www.ifm.com→myifm→Download

Attachment on vehicle
Automatic object tracking is also suitable for somewhat difficult and/or rough terrain� It recognises the next
20 objects (adjustable) next to the vehicle and passes on information such as the distance, size and posi-
tion of each object to the machine controller�
The Object Detection function enables area monitoring by attaching the Smart Sensor to a vehicle�
►Mount the Smart Sensor tilted downward on the vehicle�
►Mounting position values in the ifm Vision Assistant operating software�
5.1.3 Parametrisation
There is a separate template/wizard for area monitoring
→ Ifm Vision Assistant programming manual
Object detection range (height)
A minimal and a maximal object detection height can be defined�
●The minimal height provides for a clear separation between the floor and the objects�
●The maximal height limits the object recognition in the height (height-adjustable objects)�
> The minimal height (Zmin) should be set to 0,5 m and the maximal height (Zmax) should correspond
to the vehicle height less a tolerance (~20 cm)�
Frame rate
►Set the frame rate to 33 Hz�
Object detection type
►Set the Object Detection parameter to "Standard Mode"� (Parameter ObjectListCust_objectDetection-
Variant=0)
If a distinction is to be made between normal objects and objects with retro reflectors, the parameter
ObjectListCust_objectDetectionVariant=1 can be set�
►Set noise suppression filter to "Level 2"�
If the load on the CAN bus is too great, it can be reduced with the setting
CANoutputcycleModulo.→Operatinginstructions

5.1.4 Relevant output
The CAN messages with the result values of the detected objects (e�g� position or relevant speed) can be
received and interpreted on the controller used�
The objects are filtered via the object position for area monitoring� Objects which are located within a criti-
cal area result in a reaction, e�g� a warning signal or stopping of the vehicle�
The vehicle's own data are expected on the CAN bus (if parameter egodatamode=2, the data are not
expected)�
SeeOutput→Chapter"7 Interface" on Page 20�
5.1.5 Operating property/performance
●The detection performance is dependent on the distance, size and reflectivity of an object�
●For attachment from above:
The minimum detectable object height is dependent on the system parametrisation� Under the poorest
conditions, this is 50 cm�
●For frontal attachment:
The minimum range for the detection of persons in the monitoring area is 1 m to 15 m with normal
ambient conditions�

5.2 Reflector tracking of marked driverless vehicles
5.2.1 Introduction
The Object Detection function enables marking and identification of objects with reflectors and their
specific tracking�
Driverless transport systems (DTS) in harbour logistics can automatically detect and track other DTSs us-
ing the sensor� The distance between the DTSs can be defined depending on the speed difference�
In addition, it is possible to define areas in front of the vehicle and to monitor them for any desired objects�
5.2.2 Attachment options
►Attach Smart Sensor horizontally on vehicle at a height between 50 cm and 1�50 m�
►Mark vehicles with reflectors�
►Mounting position values in the ifm Vision Assistant operating software�
