Background knowledge

In the world of speed and passion, safety is always the first element. With the rapid development of science and technology, 3D vision technology is gradually infiltrating into the bicycle manufacturing industry, especially in the field of precision detection of brake pads, which has brought a revolutionary improvement, ensuring the safety of every cyclist and making every brake full of confidence.

The 3D vision system can capture the size differences of micron or even sub-millimeters, from thickness, shape, surface roughness and material defects. This means that each brake pad has been strictly checked before leaving the factory, to ensure the fit with the wheel hub, improve the braking efficiency, reduce wear, extend the service life, and ensure the safety of the rider.

Camera selection

Today for you to introduce the application of technology LVM2540 line laser 3D camera in the bicycle manufacturing industry testing case!
