Laser point cloud data D20 can be SLAM mapping
It can see objects within 20 meters of the surrounding 360-degree range, which is larger than the field of view of bees, and can produce flat point cloud map data in the space
High precision brushless motor customized with bearings imported from Japan is used under standard conditions with a service life of 50,000 hours
In terms of optics, they use TOF laser ranging method and a level of human eye safety to protect the laser, in line with international and domestic standards, and the high-power laser emitter tube uses fiber compression (company patent) for divergence Angle compression, making its spot smaller, thus greatly improving my vision.
In terms of machinery, they use electromagnetic non-contact rotation patent technology and passive photoelectric coding patent technology to make the structure simple, and by using a large rotating shaft external rotor motor to make its machine performance very stable, so that I greatly improve the sense of orientation.
Quality Control
- Optical component
For the laser in the laser emission module, the parameters such as wavelength accuracy and output power stability need to be strictly tested. For example, the deviation of the wavelength may affect the accurate reception and resolution of the light reflected by the liDAR on the target object, and the wavelength deviation is generally required to be controlled within a very small range, such as ±5nm.
The quality of the optical lens is also crucial. The curvature accuracy of the lens, the surface flatness and the transmittance of different wavelengths of laser light are all carefully tested. Any small flaw, such as a scratch or uneven curvature on the lens surface, can cause the laser to scatter or focus inaccurately, thus affecting the detection accuracy of the liDAR. The transmittance is generally required to reach more than 90% in a specific band.
- Electronic component
The chip on the circuit board is the "brain" of the lidar, and when conducting quality control, it is necessary to ensure that the performance of the chip meets the design requirements. For example, to test whether its data processing speed can meet the needs of liDAR to acquire and process large amounts of point cloud data in real time. At the same time, it is also necessary to check the stability of the chip in different temperature environments, because the lidar may generate heat during the working process, and the chip performance must be stable within a certain temperature range (such as -40 ℃ -85 ℃).
The parameter accuracy of capacitors, resistors and other discrete components can not be ignored. The deviation range between the nominal value and the actual value of these components should be controlled within a certain limit, such as the resistance value deviation of the resistance does not exceed ±1%, to ensure the normal operation of the circuit and the accuracy of signal transmission.
