Frequently Asked Questions About 3D Laser Scanner

The unprecedented speed of technological change has made the 3D laser scanner a very common device in many industries today. 3D measurement tools are cost-effective methods to capture data so individuals can visualise as well as analyse objects quickly and efficiently.


How does 3D scanning work?

3D laser scanning involves digitally capturing and measuring the details of physical environments or objects with laser light. A laser scanner sends light pulses at high speeds which reflect off objects and return to the scanner’s sensor.

3D laser scanning devices allow for more precise models of a given space and reduces the possibility of human error. The greater the number of scans taken, the more accurate the results will be.


Will 3D laser scanning destroy the object? What can be scanned?

3D laser scanners make use of non-contact and non-destructive technology that does not destroy the object. The scanner emits a laser beam which will reflect off objects and return to the scanner’s sensor.

Many types of objects can be scanned. Due to their odd angles, some objects may require extra scans to get enough information.

3D scanning is mainly used for objects with complex shapes and contoured surfaces, even in darkness. In these cases, due to the great amount of data needed, it is impractical to use traditional measurement methods like gauges, callipers and coordinate measuring machines.

What are point clouds and why are they important?

Point clouds represent spatial data as a collection of coordinates. They deliver data sets so individuals can visualise and analyse the 3D data.

In other words, for better visualisation and analysis, point clouds are points in a 3D series that depict an environment or object that was digitally scanned.


Which is the best 3D laser scanner?

Every object is different so deciding which 3D laser scanner to use requires an evaluation of various factors. It is generally recommended to follow the few tips below:

Accuracy: The accuracy of data is of the utmost importance because many individuals rely on the 3D data to make decisions. To ensure that the laser scanner meets the optimal standards, the machine should be calibrated on-site.

High resolution: Choose a high-resolution 3D scanner if you require a detailed 3D model of the object.  Do note that the higher the resolution, the longer it typically takes to process the data and the bulkier the scanner will be.

Up-to-date software: The software powers the 3D scanner. An updated software can handle data quickly and are usually more user-friendly

Speed: Many manufacturers prefer a 3D laser scanner that has a high number of frames and a high number of points captured per second.

Object being scanned: The best scanner depends on the size of the object, the material of the object’s surface and the amount of detail one wants to capture. Different 3D laser scanners are recommended for different uses.

The Ultimate Guide To Selecting A Good Vision Measuring System

Vision Measuring Systems

Vision measuring systems, also known as video measuring machines, are measuring instruments widely used in different industries. Many components and products in these industries have to meet a high degree of geometrical conformance and few metrology equipment can sufficiently address such rigorous demands. This is where the video measuring system comes in – it is able to inspect, measure, evaluate and/or identify objects in a fast and accurate manner.


How Are Vision Measuring Systems Different from Optical Comparators?

A vision measuring system makes use of zoom optics with better lighting and multiple sensors for a clearer resulting image. With these features, they can measure both 2D and 3D parts up to a certain precision, depending on the accuracy of the machinery. 

On the other hand, the optical comparator can only measure the 2D profile contouring of the object. 

So now you understand how a vision measuring system works. With so many companies offering a large selection of vision measuring systems, which do you choose? Below are some things to consider when selecting a good vision measuring system to meet all your metrology needs.

1. Work with an established company with a good track record.

An established vendor, preferably with over 5 years of experience, typically manufactures their own machines or has partnerships with various distributors, giving you a wide range of products to choose from at a much lower cost. Their products offered also have significant uptime and low failure rates.

Your vendor should always be up to date with the latest functions and technological trends. As vision measuring systems make use of PC-based software, it must be regularly updated so you can get the most accurate results in an efficient manner.  

It is also wise to ask for benchmarks and sample reports so you can have a good gauge on their past track record. This is proof that they will provide reliable equipment with uncompromising quality, giving you a peace of mind that you’re in good hands.

2. Good staff training is key to getting the most out of your measurement machines.

Some vision measuring systems require trained operators to operate them. Ample support, like training and metrology seminars, should be provided by your vendor.  Some vendors even provide in-house training on the operation of the machines. Well-trained operators who understand the ins and outs of the video measuring machines can make a world of difference to your research applications, production quality, design and performance specifications.

3. Opt for a machine that meets your needs.

There are many variations of the video measuring machines, each with their own unique features to suit your needs. Some machines can be manually adjusted while others are equipped with a digital colour camera.

A few vision measuring systems also have multiple sensors like a touch probe or laser on a single machine. These multi-sensor video measuring machines are highly useful for difficult-to-reach part features. Measurement accuracy varies amongst them too.

Discuss with your vendor and opt for a machine that best suits your specific needs to maximise your budget.

4. Get a vendor that provides responsive and reliable technical support.

If your machine goes down, you need answers fast. Nothing is more frustrating than having an unresponsive vendor. Relieve yourself from this stress and work with a vendor who has fully trained service engineers that can fix and calibrate your machines quickly.

Exploring 3D Laser Scanners and 3D Measurement Technology

What is 3D laser  scanning?

A popular type of measurement tool is the 3D laser scanner. 3D scanners digitally capture and measure the details of physical objects with a line of laser light. They make use of non-contact and non-destructive technology.

3D scanning is mainly used for objects with complex shapes and contoured surfaces. In these cases, due to the great amount of data needed, it is impractical to use traditional measurement methods like gauges, callipers, and coordinate measuring machines (CMM).

The 3D scanning process: Time of Flight Measurement

Light waves from the laser scanning system bounce off surfaces and are reflected back to the sensor. The sensor then calculates how far away the surface is by measuring the time taken for the light waves to be reflected back.

Within a few seconds, the distance measured is used to calculate a coordinate of the surface hit by the laser beam. During a single scan, a laser scanner collects millions of 3D coordinates. 

When the point clouds from laser scans are processed, they form a digital representation of the scanned object.


Advantages of 3D Scanning

1. Fast measurement and inspection time

Compared to traditional scanning methods, 3D scanning greatly reduces measurement and inspection time, regardless of the object’s shape or complexity.

2. More accurate for objects with complex shapes and contoured surfaces
