Glass Beads for Road Marking and Machine Vision in Automatic Driving Technology

Glass beads are commonly used in road marking to enhance visibility and retroreflectivity of the markings, particularly in low-light conditions. These beads are embedded in the paint or thermoplastic material used for road markings, and reflect light back towards the source, making the markings more visible to drivers.

Some people wonder whether automatic driving technology will eliminate road markings. At present, the answer is no.

In the context of machine vision in automatic driving technology, the retroreflective properties of glass beads can also be useful for helping automatic vehicles navigate roadways. Specifically, the reflective properties of the glass beads can help sensors on the vehicle detect and identify the location and boundaries of the road markings. This information can be used to help the vehicle stay centered in its lane and navigate safely and accurately.

To make the most of the retroreflective  properties of glass beads in automatic driving， it is important to carefully select the type and quality of glass beads used in road marking. Factors such as the size, shape, and refractive index of the beads can all affect their retroreflective properties and the accuracy of the information they provide to sensors on automatic vehicles.

Overall, glass beads used in road marking can be an important tool for improving safety and visibility on roadways, and can also be useful for machine vision in automatic driving technology. By carefully selecting and using high-quality glass beads, it is possible to enhance the effectiveness of road markings and improve the accuracy and safety of automatic vehicles.
