According to reports, the green laser pointer radar sensor uses light pulses to achieve remote detection of the target, the light emitted by the sensor will be reflected by the clearcoat, or by the basecoat. Reflected or absorbed by the internal pigments.
Today, there is an information gap between the paint manufacturer and the Lidar technology company, because the latter does not stipulate the most efficient paint, ensuring that enough light can be reflected back and applied to all colors.
In addition to the darker paint, which can pose a challenge to the green laser pointer reflection, a metallic color that is too bright may cause too much reflection. When using the background color of the simulator, as the position of the vehicle changes, the surface light reflection will also change, which will affect the optical signal of the laser radar.
It is said that if it is white paint, the light emitted by the laser radar can be returned to the vehicle 100%, which is convenient for the sensor to realize all-round exploration of roads and targets from various angles and directions.
To ensure optimum performance of the self-driving in-vehicle lidar, it may be necessary to contact the paint shop to ensure that the vehicle's paint is continuously updated.
Autopilot vehicles using lidar will need to ensure that all vehicles on the road have good performance, which is inseparable from the cooperation of the paint shop, and the current painting process has not yet seen its impact.
The lidar green laser pointer requires a custom-colored paint to match, ensuring its useful light reflection performance. The paint shop will play an important role.
