Introduced in the late 1990s, laser scanners quickly became a hit in the engineering industry. Unlike previous data collection methods, which were time consuming, costly and inaccurate, 3D laser scanning was fast, affordable and highly accurate. Compared to scanning, older surveys are exorbitantly expensive for two reasons. It requires more involvement of the surveyor and the creation of 2D and 3D drawings. Scans, on the other hand, minimize investigator involvement and generate computer data models that customers can manipulate as they see fit, eliminating the need for further research to provide a new perspective on topics that have already been investigated. increase.
Some companies buy their own scanning equipment, while others spend their needs on scanning services that specialize in laser scanning design. In most cases, the decision to scan internally or outsource will determine if the company can save more by outsourcing rather than buying 6-digit costly scanning equipment. However, regardless of company decisions, data for tasks such as pipeline collision control, 3D terrain site scanning, building and site modeling, 3D animation, and BIM modeling are typically used using one or more of the three types of scanners.

Laser Scan Engineer: Three Commonly Used Scanners
In engineering, scan data is first used to conceptualize and model the design. But in the end, information links between architects and construction companies will be easier. Depending on your business focus, you can use all of the following types of scanners for both contact, flight time, and triangulation purposes: 1. Contact scanner
As the name implies, the contact model collects data from the recording object by contacting it with a sensitive probe that can collect very accurate data. The advantage of the contact model is its very high accuracy. Their drawbacks are that they cannot scan large objects and that the recording function can damage sensitive objects.
2.2. Tim-of-Flight Scanner
The flight time model is the opposite of the contact scanner. A special rangefinder is used to measure the round-trip time from the scanner to the subject and vice versa to fire the laser at a larger, more distant study subject. The advantage of time-of-flight scanning is that you can collect data from a wide range of topics such as large buildings, the natural environment, and terrain areas. The downside is that it provides detailed data, but not infinitely detailed data, but when the latter is needed, companies don’t use it.
3. Triangulation scanner
The triangulation model provides a pattern of light passing through the object to be recorded, with a special camera for recording deviations due to the quality of the surface of the subject. The advantage is very high accuracy and the ability to mount multiple stations on a large scan target to record the entire dataset. There are no predictable drawbacks when used within those capacities.
