In addition to education, HLD projectors are also being deployed in the home market. At this year’s CCBN2018 exhibition, a product called “Natural Light TV” has attracted the attention of many people. In fact, this product is a reflective ultra-short focus product that uses an HLD light source. However, the green laser pointer in the domestic field…
The service life of HLD is also similar to that of green laser pointer, which can theoretically reach about 20,000 hours. But compared with laser, HLD has higher tolerance, which means HLD has a longer life at the same temperature. It is well known that the temperature inside the projector is high, so this will affect…
Although the sales volume of the home projection market has increased significantly in recent years, it still occupies a pivotal position in the field of education in the entire market. Therefore, industry leaders in the education market have always attached great importance to it. In 2018, major manufacturers launched HLD light source products for the…
In recent years, autonomous driving technology has taken the world by storm and is considered to be the next innovation in technology. In addition to the large-scale layout of traditional car manufacturers, technology companies have played an important role in promoting, such as Google, Uber, Baidu, Nvidia and so on. With the continuous advancement of green…
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…
