As a science that explores human history and culture, archaeology has always relied on excavation and manual recording to preserve artifacts and cultural relics. However, this discipline has ushered in a technological revolution in recent years. The introduction of 3D scanning technology has changed the traditional way of working, making archaeological research more efficient, accurate and interactive. With its unique non-contact measurement method, 3D scanners have completely changed the way archaeologists obtain, store and analyze data, bringing great changes to cultural heritage protection. 1. How 3D Scanning Works 3D scanners capture point cloud data on the surface of an object through lasers, structured light or other sensors to generate a three-dimensional model of the object. These devices can perform high-precision scans of objects of various materials, from tiny artifacts to entire archaeological sites, and can be digitally preserved. Different types of scanners have their own...

In the field of modern 3D scanning technology, structured light and laser 3D scanners are two widely used scanning methods. They provide precise 3D model building tools for the manufacturing, medical, conservation and entertainment industries. However, there are significant differences between structured light and laser scanners in terms of principles, performance, and applicable scenarios. This article will provide an in-depth analysis of their similarities, differences, advantages and disadvantages to help users choose the appropriate scanning technology. 1. The difference between scanning principles Structured light 3D scanner How it works: A structured light scanner uses a projector to project a preset grating pattern (such as stripes or dots) onto the target object. These patterns deform as they pass through the object's surface, and the camera captures these deformed light images. By calculating the degree and angle of pattern deformation, the system is able to generate a thr...
