1. Welcome

Product Introduction

Mech-Eye 3D Laser Profiler (“laser profiler”) is developed by Mech-Mind and can output high-quality

intensity images, depth maps, and point clouds, suitable for applications of high-accuracy

inspection and measurement in industries such as consumer electronics, automobile, EV battery,

and home appliances.

You can configure and control the laser profiler through the graphical interface software Mech-Eye

Viewer or the application programming interface Mech-Eye API developed by Mech-Mind. Mech-

Eye Viewer is only available on Windows.

Meanwhile, the laser profiler is also compliant with the GenICam standard and can be controlled by

third-party machine vision software also compliant with the GenICam standard (“GenICam

clients”).

How the Laser Profiler Works

The following topics provide the basic knowledge on laser profiler, including how the laser profiler

scans an object and generates data, as well as how the laser profiler can be integrated to work

with other devices in a system. These topics are the foundation for understanding how to use and

configure the laser profiler.

•Understand how the laser profiler scans an object and generates data

•Understand how the laser profiler can be integrated into a system

•Getting started with the laser profiler

Use the Laser Profiler

The following topics provide instructions on using Mech-Eye Viewer or Mech-Eye API to adjust the

parameters of the laser profiler and acquire data.

•Use Mech-Eye Viewer to adjust parameters and acquire data

•Understand the functional hierarchy and operation workflow of Mech-Eye API

Check Ports and Indicator Lights

The laser profiler consists of a sensor head and controller. The following sections introduce the

sensor head and controller of the laser profiler.

Sensor Head

Refer to the following diagrams and table and check the function of each part of the sensor.

No. Name Function

①Laser emitter Emits laser light.

②Receiver unit Receives the laser light reflected by the target surface.

③Controller port Used to connect to the controller.

④LINK indicator light

Off: not connected to network

Blinking green: data in transmission (2.5 Gbps)

Blinking yellow: data in transmission (10/100/1000 Mbps)

⑤LASER ON indicator

light

Off: laser light not emitted

Solid on: laser light being emitted

⑥POWER indicator

light

Off: not connected to power

Solid green: normal voltage

⑦Shading device

mounting hole Used to mount shading device onto the sensor head.

Controller

Please refer to the following figures and tables and check the functions of the ports and indicator

lights on the controller.

Mech-Eye 3D Laser Profiler User Manual

No. Name Function

①Sensor head port Used to connect to the sensor head.

②RUN indicator light On: data acquisition in progress

Off: no ongoing data acquisition

③PWR indicator light Solid green: normal voltage

Off: abnormal voltage or not connected to power

④ERR indicator light Blinking: malfunctioning

Off: operating normally

⑤Power connector

24V: +24 V DC input

0V: 0 V DC input

PE: grounding

⑥Input Signal

Blinking: data transmission in progress

Solid: no ongoing data transmission

⑩RJ45 Ethernet port Used to connect the RJ45 connector of the Ethernet cable.

Mounting and Connection

Mount the Sensor Head

Mech-Eye 3D Laser Profiler User Manual

Before Mounting the Sensor Head

Before mounting the sensor head, please check the following precautions:

•The shape of the target object may produce blind spots in the measurement range. Please

evaluate the effect of blind spots on scanning before mounting the sensor head. The laser light

of this product is emitted almost in parallel, and therefore blind spots are rarely present.

Shadowed area represents blind spot Obtained profile

•Make sure that the laser light reflected by the target object is not blocked and can reach the

receiver unit.

Incorrect Correct

•Stray light is produced if the laser light is reflected by surrounding objects such as walls.

Please evaluate the effect of stray light on scanning before mounting the sensor head.

Mech-Eye 3D Laser Profiler User Manual

•To ensure that the heat from the sensor head is well dissipated, please mount it to a metal

plate that has at least one surface with an area of 200 square centimeters or more.

Mounting Method

If the mounting plate is too thick, please prepare M5 bolts with the appropriate length. Please

prepare M5 nuts and open-end wrench.

When installing the laser profiler, please refer to the reference distance of the laser profiler.

Method 1

As shown below, place four M5 × 8 bolts in the holes, use the 4 mm hex key to loosely screw on

the bolts in the specified order, and then fully tighten all the bolts in the specified order.

Method 2

As shown below, place the Φ5 gaskets and then the M5 × 70 bolts in the holes, and then use an

open-end wrench to tighten the nuts.

Connect the Sensor Head and Controller

Connect the right-angle connector of the sensor-head-to-controller cable to the controller port on

the sensor head and the straight connector to the sensor head port on the controller.
