PRINCIPLES

OF

OPERATION

HDL-64E

S2

and

S2.l

User's

Manua

l

The

sensor

operates

,

instead

of

a

single

laser

firing

through

a

rotating

mirror

,

with

64

lasers

fixed

mounted

on

upper

and

lower

laser

blocks

,

each

housing

32

lasers.

Both

laser

blocks

rotate

as

a

single

unit.

With

this

design

each

of

the

lasers

fires

tens

of

thousands

of

times

per

second

,

providing

ex

ponentially

more

data

points/second

and

a

more

data-intensive

point

cloud

than

a

rotating

mirror

design

.

The

sensor

delivers

a

360°

horizontal

Field

of

View

(HFOV)

and

a

26.8°

vertical

FOV

(31.5°

VFOV

for

the

S2

.

1).

Additionally

,

state-of-the-art

digital

signal

processing

and

waveform

analysis

are

employed

to

provide

high

accuracy

,

extended

distance

sensing

and

intensity

data.

The

sensor

is

rated

to

provide

usable

returns

up

to

120

meters.

T

he

sensor

employs

a

direct

drive

motor

system

with

no

belts

or

chains

in

the

drive

train.

•

The

sensor

can

be

mounted

at

any

angle

from

O

to

90°

with

respect

to

its

base

.

Refer

to

Appendix

A

for

complete

dimensions.

For

all

mounting

options,

mount

the

sensor

to

withstand

vibration

and

shock

w~hout

risk

of

detachment.

Although

helpful

for

longer

life

,

the

unit

doesn

't

need

to

be

shock

proofed

as

it's

designed

to

withstand

standard

automotive

G-forces.

The

sensor

is

weatherproofed

to

withstand

wind

,

rain

and

other

adverse

weather

conditions.

The

spinning

of

the

sensor

helps

it

shed

excess

water

from

the

that

could

The

following

provides

more

detail

on

each

of

the

above

steps

.

1.

Establish

communication

with

the

sensor

.

The

sensor

broadcasts

UDP

packets

.

By

using

a

network

monitoring

tool

,

such

as

Wireshark

,

you

can

capture

and

observe

the

packets

as

they

are

generated

by

the

sensor.

See

Appendix

E

for

the

UDP

packet

format.

The

default

sou

r

ce

IP

address

for

the

sensor

is

192.168.3.043

,

and

the

destination

IP

address

is

192.168.3.255.

To

change

these

IP

addresses

,

see

page

11.

2.

Create

an

internal

calibration

table

either

from

the

calibration

data

included

in-stream

from

the

sensor

or

from

the

included

db.xml

data

file

.

This

table

must

be

built

and

stored

internal

to

the

po

i

nt-cloud

processing

software.

The

easiest

and

most

reliable

way

to

build

the

calibration

table

is

by

reading

the

calibration

data

directly

from

the

UDP

data

packets

.A Matlab

example

of

reading

and

building

such

a

table

can

be

found

in

Appendix

and

on

the

CD

included

with

the

sensor

named

Alternatively

,

the

can

be

in

the

included
