What is three-dimensional measurement
Three-dimensional measurement (also known as three-dimensional measurement) is a technology that obtains three-dimensional coordinate data of objects through high-precision equipment. It is widely used in industrial manufacturing, quality control, reverse engineering and other fields. With the development of intelligent manufacturing, three-dimensional measurement technology has become an indispensable link in modern industry. This article will combine the hot topics on the Internet in the past 10 days to analyze the principles, applications and latest technology trends of three-dimensional measurement.
1. Basic principles of three-dimensional measurement
Three-dimensional measurement captures the spatial coordinates (X, Y, Z values) of the object surface through sensors or probes, and generates three-dimensional point cloud data. Its core equipment includes:
| Device type | Working principle | Accuracy range |
|---|---|---|
| Contact coordinate measuring machine (CMM) | Mechanical probe contacts the surface of the object to collect data | ±1~5 micron |
| laser scanner | Non-contact laser reflection ranging | ±10~50 microns |
| Optical measurement system | Multi-camera stereo vision reconstruction | ±5~100 microns |
2. Recent popular application cases (last 10 days)
According to data monitoring across the entire network, three-dimensional measurement technology in the following fields is the most discussed:
| Industry | Application scenarios | Hot search index |
|---|---|---|
| New energy vehicles | Battery module size detection | ★★★★☆ |
