3D Laser Radar (3DLR)'s Features and Performance

■Features

Illustration of the 3DLR's moving obstacle detection method.

■Performance

◎Accurately captures the form, position and movement of an object in real time.

◎Informs the object's location with high precision by directly measuring the distance from 　object to 3DLR head.

◎IH I's 3DLR is set apart from simple image sensors by its ability to provide consistent and 　reliable detection and tracking of objects regardless of bad weather conditions and 　poor lighting.

◎The 3DLR has no adverse effect on electronic devices as its laser uses light instead of radio 　waves.

●Two-axis scanning mechanism

Laser light emitted within measuring range.The distance to each point is calculated.

By scanning the laser light along the horizontal and vertical axis of

the detection area a 3D detection result is possible.

●Sensing performanceDetection time is 0.1 sec (min) to 3. sec (max) for a frame with

angles of 90 h゚orizontally and 60 ゚vertically.

●Unique moving-object detection algorithm.The 3DLR's unique moving-object detection algorithm enables

precise detection and tracking of objects such as pedestrians

and vehicles on the road.

●Consistently logical detection even in 　snowfallBased on it's unique noise elimination method the 3DLR

performs reliable object detection and tracking regardless of bad

environmental conditions such as snow and rail fall.

●Highly precise measurement performance 　even over long distances.The 3DLR uses pulsed laser light to capture objects. It employs

the TOF (Time of �ight) method which calculates the time taken for

the laser light to return to its point of emittance once re�ected

off of a detected object.

Instantly capturing pro�le, location and movement.The 3DLR detects objects in real time to enhance safety regardless of bad environmental conditions and poor lighting.

■ Junction Safety SystemInstalled at over 50 junctions to date●One 3D Laser Radar(3DLR) unit can monitor a large area (90 h゚orizontal, 60 v゚erticle and up to 200m ahead).

●The 3DLR detects vehicles and pedestrians instantly at an intersection. A warning message is then relayed 　to the driver in real time.

●The 3DLR is utilized as an infrastructure sensor for DSSS(Driving Safety Support System) across cities in Japan.

The 3DLR is already being actively used in many aspects of the town around us.

◎Road condition and 3DLR detection image

●One 3D Laser Radar (3DLR) unit can cover the whole detection area of a level crossing＊

(＊A general size of the level crossing. The possible detection area is 60 h゚orizontal, 30゜vertical and up to 30m ahead.)

●The 3DLR is contributing to the prevention of accidents at level crossings by detecting obstacles (vehicles etc.), when they are trapped inside a closed crossing.

●The 3DLR's installation and after-care maintenance is carried out with ease as it is not placed within the track clearance.

Oncoming vehicles and pedestrians can besimultaneosly detected by one 3DLR unit.

■Ship MonitoringThe 3DLR can be used to

monitor ships entering a

harbor, a �ood-gate or etc.

■Crowd MonitoringThe 3DLR can be used to

relieve overcrowding by

detecting the human traf�c

�ow in a set area.

■Multiple Vehicle 　Collision prevention

The 3DLR detects slow

moving and stationary

vehicles up-ahead to avoid

a multiple vehicle collision

around a sharp curve.
