3D laser scanning measurement uses a laser beam to scan the surface of an object, obtain its 3D coordinate data, and generate a model. It is widely used in architecture, engineering, cultural heritage protection and other fields.
Working principle
Laser emission and reception: The laser emits a laser beam and the receiver records the reflected light.
Scanning and data acquisition: Cover the entire surface of the object by rotating or moving the scanning head.
Data processing: Convert the collected data into a model.
Main technology
Time of flight (TOF): Calculate the distance by measuring the round-trip time of the laser.
Phase difference method: Calculate the distance by measuring the phase change of the reflected laser.
Triangulation method: Calculate the distance using the geometric relationship between the laser source, receiver and object.Application areas
Architecture and engineering: used for building measurement, construction monitoring and quality inspection.
Cultural heritage protection: used for digital recording and restoration of cultural relics and monuments.
Manufacturing: used for product design, quality inspection and reverse engineering.
Topographic mapping: used for topographic measurement, geological disaster monitoring and urban planning.
Advantages
High precision: can reach millimeter or even sub-millimeter level.
High efficiency: quickly obtain large amounts of data.
Non-contact: avoid damage to objects.
Comprehensive: can obtain complete three-dimensional information on the surface of an object.<\/figcaption><\/figure>\n\n\n\n
