Introduction
A Line Laser 3D Camera, often referred to as a 3D Laser Profile Sensor, is a precision measurement device that utilizes laser triangulation to capture the three-dimensional shape of objects. By projecting a laser line onto a surface and capturing the reflected light at a specific angle, the system calculates precise height (Z-axis) and width (X-axis) data. This technology is essential for high-speed automated lines where sub-millimeter accuracy is required for displacement measurement, surface defect detection, and complex 3D contour mapping of moving parts.
Working Principle
1. Laser Projection
A structured laser beam is flattened into a thin line and projected onto the target surface, creating a continuous light contour that follows the object's geometry.
2. Triangulation
The internal image sensor observes the laser line at a fixed angle. As the object height changes, the position of the line on the sensor shifts according to geometric triangulation.
3. Profile Extraction
Embedded FPGA processors analyze each frame to calculate the center of the laser line with sub-pixel precision, converting optical data into a 2D profile (X-Z coordinates).
4. 3D Cloud Assembly
By moving either the camera or the object, consecutive profiles are stacked to reconstruct a high-resolution 3D point cloud for volumetric and dimensional analysis.
