History and Technological of 3D Laser Scanning is a process of capturing the physical shape and appearance of objects or environments in a digital format. It allows for the creation of highly accurate and detailed three-dimensional representations of real-world objects or spaces.
History of 3D laser scanning through a period
Leveraging laser sources and digital cameras, 3D scanning technology, particularly laser scanning, enables the capture of highly precise data encompassing 3D coordinates, shapes, and surface colors of real-world objects. History and Technological of 3D laser scanning technology advanced exceptional accuracy, color fidelity, and remarkable speed in acquiring data. The collected data serves as the foundation for generating 3D models of objects on a 1:1 scale. Various 3D scanning technologies exist, each with distinct advantages and limitations.
FARO Technologies Inc (USA), a renowned precision measurement technology company, gained global recognition in 2017 as the most trusted provider of 3D scanners. With more than 15 years of experience, FARO has consistently improved and expanded its line of 3D scanners, enhancing accuracy, accelerating data acquisition, and widening the range of potential applications across numerous fields.
How does FARO scanner work in real-life construction
The FARO 3D scanning technology operates based on the principles of laser scanning. FARO 3D scanners use a combination of lasers, sensors, and cameras to capture detailed data about the geometry, texture, and color of objects or environments. Here’s an overview of the operation of FARO Scan 3D:
- Laser Scanning: The FARO 3D scanner emits laser beams that sweep across the object or scene being scanned. The lasers are typically of a specific wavelength and are carefully controlled to ensure accuracy and precision.
- Time-of-Flight Measurement: As the laser beams hit the object’s surface, they reflect back to the scanner. The scanner’s sensors measure the time it takes for the laser beams to travel to the object and return, allowing for precise distance calculations.
- Data Capture: The scanner captures the reflected laser beams and records the corresponding distance measurements for each point on the object’s surface. This data is collected as a point cloud, which is a set of three-dimensional coordinates that represent the object’s geometry.
- Color and Texture Acquisition: In addition to capturing the point cloud data, FARO scanners often include built-in cameras. These cameras capture high-resolution images of the object’s surface, capturing color and texture information. The collected images are then integrated with the corresponding points in the point cloud.
- Real-Time Feedback: FARO scanners offer real-time feedback, allowing the user to see the scanned data as it is captured. This feature enables immediate verification of the scanning quality, coverage, and data accuracy, ensuring that the desired information is being captured effectively.
- Data Processing: Once the scanning process is complete, the captured data, including the point cloud and color/texture information, is transferred to specialized software. The software provided by FARO, such as FARO SCENE or FARO As-Built, allows for data registration, alignment, filtering, and fusion of multiple scans.
- 3D Model Generation: Using the processed data, the software generates a comprehensive 3D model of the scanned object or environment. This model can be visualized, analyzed, and further manipulated for various applications, such as CAD, reverse engineering, inspection, documentation, or virtual reality.
