3D Laser Scanning Services - The Workflow

Technology Overview - 3D Laser Scanning Services

3D laser scanning / digitising is a technology that captures the digital shape of physical objects.Its use can decrease engineering costs, allow reverse engineering, shorten programmes, generate “as-built”documentation and provide a whole new perspective to projects.

How 3D Laser Scanning Works

Laser scanning technology is referred to as "terrestrial laser scanning" or "high definition surveying" and is a precise method of 3D data acquisition. The tripod mounted scanner emits a narrow laser beam to scan objects of interest, producing a 360 degree three dimensional "point-cloud" of survey information.
Sweeping its beam (using internal mirrors and motors) over the surrounding scene, virtually blanketing the selected scene with laser measurements. As the beam hits objects in the surrounding area the laser light is reflected back to the scanner. The scanner detects the return signal and calculates a distance measurement. 
Combining these distance measurements with internal angle measurements of the scanner's rotating mirrors, relative X, Y, Z co-ordinates can be established for each point on a surface that the beam hits. A laser scanner collects hundreds of thousands of closely spaced surface geometry measurements (points), to high accuracy, in just minutes. These surface points can then be displayed on a computer system; the resulting "point cloud" looks like a dense, 3D bit-map image of the surveyed area. It can be viewed and navigated much like a 3D model. However, each of these scanned points is not simply a "dumb" pixel, it has true site X, Y and Z coordinates that can be interrogated.

What is 3D Laser Scanning used for ?

3D laser scanning is commonly used to accurately capture and store "as-built" or "existing" information, often from safe remote locations, to assist the design process. From mechanical plant to buildings and structures, its function is always the same; to record and transfer the survey area into a digital computer format that can be successfully interrogated remotely.

For example, the 3D model would offer not only infinite viewpoint options but can be sliced horizontally for plan presentation or sliced vertically for sectional information.Utilising specialist software allows us to cross-examine this data to establish inaccessible pipework/equipment centre lines/details remotely without requirement for scaffolding, plus the ability to model these areas for export or cross/clash check against other CAD systems.

Quality, Accuracy & Efficiency

Laser scanning offers an ideal input for designing modificationsto existing sites or facilities. Clash detection within the software ensures that component conflicts can be avoided during design. Due to its ability to quickly record even the most complex arrangements within a potentially hazardous process installation, with both range and accuracy, 3D laser scanning has proved its potential to add value to Projects.

 

3D Laser Scanning Survey Services

Our company is based in Indonesia and we can provide a world wide services for 3D Laser Scanning survey services.

We work to a quality management system that complies with ISO 9001:2000 and we are currently working towards formal accreditation.

Since inception, we have grown in size and we now employ sixty people in total, all of who can capture the data and produce the engineering deliverable. We are committed to our staff development programme.

We now own our laser scanners equipment. This new product can capture 10,000 points per second with a 360° x 270° field of view and 5mm accuracy over 50m range. We have developed the laser scanning technique in conjunction with several customers and our ability to capture data in various technical environments and produce accurate engineering deliverables is second to none.

Traditionally engineering and construction methods rely on engineers collecting and assembling information from existing drawings and taking many manual field measurements. These tedious and time-consuming activities, historically, expose projects to unacceptable schedule and financial risks because of inaccurate data. Today, as-built 3D laser scanning technology offers a very cost-effective solution for both 2D or 3D as-built retrofit project. We works with this technology in both industrial and civil applications and offers a complete and proven implementation as-built package.

We produce the required deliverables in a number of :

• 3D or 2D CAD and / or Microstation or CadWorx formats.
• Produce a 3D Dumb PDMS or PDS model.
• Clash Detection Analysis between existing 3D model vs as-built survey data.
• Architectural
• Dimension Control and Volume Calculation
• And also for land topography, hydrography and 3D scanning under water
• Air Photography using remote control airplane
