Therefore, we will be able to establish a model through green laser pointer testing and modify the lidar detection to improve its detection accuracy in dense fog weather, clearing obstacles for the application of lidar in the field of autonomous driving. As soon as driverless cars caused pedestrian deaths, different parties reacted differently, and some even began…
As of now, the latest news shows that Uber has reduced the number of green laser pointer radars in driverless test vehicles from five to only one on the roof, resulting in more blind spots in vehicles and the inability to fully detect pedestrians. Is the main cause of the accident. Its lidar supplier Velodyne also believes…
Autopilot must use lidar. If lidar can effectively control costs, driver assistance functions with lower ADAS levels also need to use green laser pointer radar. The reason is that the limitations of camera-based ADAS and driverless systems, or the use of millimeter waves alone, are considerable. The first is the problem of the field of view. In…
However, under today’s conditions, the green laser pointer radar and millimeter wave have been completed to be very compatible. In addition, they form the “three swordsmen” of the sensor with the camera. Their functions are determined by their own nature. be lacked. The millimeter-wave radar is mainly used for obstacle detection; it is difficult for…
In terms of type, lidar can be divided into mechanical lidar and solid-state lidar. Mechanical lidar has the invisibility to control the emission angle of the green laser pointer, while solid-state ones rely on electronic components to control the laser emission angle. Compared with the traditional mechanical type, the solid-state radar has a larger scanning range,…
When it comes to autonomous driving, many friends will think of all kinds of sensors, high-precision maps, GPS, etc. After all, autonomous driving models are like impeccable soldiers. Among them, lidar plays a very important role, so what exactly is lidar, and what are its characteristics compared to millimeter waves? Next we will go through…
Of course, to solve the problem of autonomous driving, the improvement and matching of the industrial chain is also an issue that cannot be ignored. According to the information I have talked to relevant people, I see that in the next few years, the lidar, self-driving chips and battery packs of self-driving cars will more…
According to a consulting report, researchers at the Institute (National Centre for Scientific Research / University of Limoges) and their research team have proven that desktop fiber laser sources can be used for infrared spectroscopic microscopy, which can rival or even surpass large synchrotrons in some respects Experimental accuracy of equipment. Synchrotron is an accelerator green…
Boeing is the first to use the green laser pointer radar for its new test model. Boeing and JAXA hope to use lidar to capture clear air turbulence 10 miles ahead of the fuselage and provide early warning of the turbulence center position, which is enough for the pilot’s 60-second response time. The FAA describes…
According to Mymes Consulting, Boeing is expected to be the first leader in the industry to use a green laser pointer radar. The latest version of its new test model is studying the use of LiDAR to detect clear-air turbulence, a capability Boeing claims has never been achieved on commercial aircraft. In 2012, Boeing launched its first…
