The output of the lidar is no longer the original point cloud data, but also the location and classification of each obstacle space, which type is it, and speed information. There are many things that laser pointer radar can do, including positioning, obstacle detection, classification and tracking, lane line detection, roadside detection, and so on. Lidar plays a very important role in the work of perception.
Whether it’s a low-speed car, a park car, a logistics car, or a car driving on a highway, we hope that we can contribute. Based on lidar lane line detection and road edge detection. The detection of lane lines based on laser radar is still relatively good. The lane lines on the road are generally white and yellow, so we will make the reflection intensity method in advance, so that the lidar can easily extract the lane lines. Because it is disturbed during the day and night.
The roadside detection can do some training according to the geometry of the roadside, and now the height of the roadside can be extracted by more than ten centimeters. Lidar is used to track objects, which is equivalent to calculating each object that is recognized, and dividing whether it is a bicycle, truck, pedestrian or private car. After recognition, in addition to the speed of the self-driving car, we can also track the speed of the car in front, as well as the horizontal and vertical distance of the car in front of the car.
In the fiber amplification of ultra-fast laser pulses, a single fiber has achieved a power of nearly 1 kW, and through the bundling technology, it is now feasible to upgrade to 5 kW. Although these systems are being developed for research centers such as ELI, developing reliable beam transmission methods remains a major challenge for industrial systems.
The upgrade of single-mode fiber red laser pointer and femtosecond fiber amplifier will require a lot of additional research work. This effort will be supported by a brand new building next to it. The construction of this new fiber optic technology center was completed in 2016 and has a dedicated laboratory for manufacturing and characterizing active optical fibers, passive optical fibers, and nanostructured optical fibers. A separate drawing tower for manufacturing special optical fibers will also be installed.
