3D laser scanners for precise measurements
3D laser scanners are advanced devices used in industry, engineering, architecture, medicine and many other fields to obtain precise and accurate measurement data from 3D objects. Thanks to their advantages, they are increasingly popular and used in various industries where accurate surface and shape measurements are required.
3D laser scanners work by measuring the distance between the device and the surface of the scanned object. The scanner uses a laser beam that is directed at the surface of the object and then detects the reflection of this beam. The time it takes for the beam to return to the scanner is analysed to determine the distance between the scanner and the surface. With advanced Time of Flight or laser interferometry technologies, the scanners are able to obtain highly accurate measurements.
Advantages:
- Precision: They are extremely precise, allowing detailed measurement data to be obtained with micrometre-level accuracy.
- They can operate very quickly, allowing large areas to be scanned in a short period of time.
- Non-contact scanning: Thanks to the use of laser beams, the scanners can operate non-contact, which is particularly useful for scanning delicate and complex surfaces that may be damaged by traditional measuring methods.
- They are versatile and can be used in a wide variety of industries, from automotive and aerospace to architecture, medicine, surveying or art.
- Replication and modelling: With obtained 3D data, it is easy to create digital models of objects that can be used for analysis, design and 3D printing.
- They provide an advanced and versatile tool that enables precise measurement and creation of 3D digital models of objects. Their accuracy, speed and non-contact scanning capability make them an invaluable tool in many fields where precise and accurate surface and shape measurements are required.
Stationary or handheld 3D scanner?
Stationary 3D laser scanners are permanently mounted on a tripod or base. They are characterised by high measurement precision and long range, making them ideal for scanning larger objects such as buildings, infrastructure or factory equipment. Additionally, due to their stable positioning, scanning with stationary scanners is easier and more precise. However, due to their size and weight, they are less mobile and more limited in terms of scanning hard-to-reach areas.
On the other hand, handheld 3D laser scanners allow the scanning of any shape and size of objects, making them more flexible in application. Because of the manual operation, a handheld 3D scanner can achieve the same precision with the latest models as their stationary counterparts.
When it comes to choosing between a stationary and handheld 3D scanner, the needs and requirements of the specific project must be taken into account. For scanning larger objects in a precise and controlled manner, a stationary 3D laser scanner may be suitable. If, on the other hand, mobility and scanning flexibility are key, a handheld 3D may be better. One sure solution on the market is the ZG-branded scanners, specifically the RigelSLAM-S model, which is used for measuring large objects, but with this device we can do this manually by walking around the scanned objects
3D laser scanner for precise measurements – what to look for when choosing one
When choosing a 3D laser scanner, there are a number of factors to look at in order to select the right model for your needs. The most important factor is to look at the scanning distance parameter and see if the scanner can collect data at close tange and over longer distances. This is important if we will be scanning a variety of objects of different sizes. Another factor we need to consider is the resolution of the scan. Higher accuracy is particularly important when collecting data for design purposes and quality control. Scanning speed is also particularly important for the latter option. Faster 3D scanners allow the process of capturing data for measurement purposes to be carried out efficiently, and here we enter the area of software, as its type is very often coupled with its speed. Another point is that good software will allow the data obtained to be more easily edited and analysed, which will also streamline the whole process. Other parameters to pay attention to are:
- Lighting requirements: Some 3D scanners require adequate lighting for good results. Make sure your environmental conditions are compatible with the scanner’s requirements.
- Ease of use: Make sure your scanner is easy to use and not too complicated to set up.
- Scanning frequency: If you plan to scan objects on a regular basis, pay attention to the maximum number of scans that can be performed within a certain time period.
- Technical support and warranty: Check the warranty terms and conditions and what technical support the scanner manufacturer offers.
Stationary 3D laser scanner for volumetric measurements
With the Leica RTC360 scanner we provide precise volumetric scanning services. The scanner is perfect for 3D scanning of buildings, industrial installations and large objects. The accuracy of these devices reaches up to 1mm. Contact us for service with this or any other scanner. We have over a dozen other scanners for professional tasks
Hand-held 3D laser scanner for volumetric measurements
A very interesting 3D laser scanner for precise volumetric measurements. It is the first scanner designed for scanning large objects such as buildings, installations, green areas, large machinery and vehicles, or earth masses, which are not scanned stationary, but while walking. The RigelSlam scanner is a unique tool that, thanks to its algorithms, can scan without reference points. It creates a real-time visualisation of the object being scanned, which speeds up work in an unprecedented way. Add to this a precision of 2-5 cm at a distance of 120 metres (0 – 3 cm under normal conditions) and you have an interesting tool that is worth looking into. The scanner is available for sale
3D laser scanner for precise measurements without reference points
An innovative handheld 3D laser scanner for ultra-precise measurements equipped with a photogrammetry system. Photogrammetry assists the laser scanner in determining its position, so that in a room where we have once taken measurements, we can take subsequent scans without reference points. Simply turn the scanner on and scan. the lack of taping translates into speed of use, which can be important in some industries such as quality control, The MarvelScan scanner also has a scanning function using photogrammetry and reference points, so we are able to achieve the highest possible scanning precision (down to 0.01 mm). The scanner is available for sale
3D laser scanners, worth its price
The price of laser scanners is influenced by many factors, the most important of which are the measurement capabilities, the build quality and the technical solutions to facilitate the work. The accuracy and resolution of scanners is the element that influences the price the most and if you expect higher precision the more you have to pay for the scanner, The dependence of the price of scanners on the quality of measurements is closely related to the more advanced technology, especially in the form of optical components. Laser scanners have different scanning areas, which is also a factor in the price of the equipment. Scanners that can scan larger areas at a time tend to be more expensive than those with a smaller scanning area. The situation is similar with scanning speed, and here the standard will be that the faster the scanner scans, the faster it processes the data and presents the computed results in real time, the greater the burden on our budget. In this case, the speed of the whole system is influenced by factors such as the development of specialised software, the quality of the data processing components used. To sum up, the price of 3D laser scanners will depend on the quality and speed of measurements, and additional facilitations such as scanning in difficult conditions and the mobility of equipment will increase this price.
Small and precise 3D laser scanner – the ideal scanner for quality control
A scanner from ZG that impresses with its scanning precision, yet is small lightweight and comfortable. It is the ergonomics of this scanner that makes it an interesting proposition for people who scan a lot. The CereScan scanner weighs just 650 grams so it is easy to hold and take long measurements. The size of the scanner not only helps in its use, but also affects the placement of the sensors. With less spacing between them, it catches cavities and holes well.
