AI Technical Summary

Problems solved by technology

Building a 3D lidar imaging system plays an important role in studying the principle of laser ranging, the construction method of three-dimensional imaging, and improving the performance of lidar. Single-point laser rangefinders on the market are relatively common, but they can only measure specific areas on the target. Compared with laser range finders, the price of laser radar products on the market is much higher. Reducing the cost of laser radar and making it closer to civilian use is an important problem to be solved.

[0003] With the increasing shortage of energy and the seriousness of environmental problems, more and more attention has been paid to energy-saving and environmentally friendly products. In the lighting street lamp industry, scientific and technological workers have invented semiconductor diode (LED) street lamps. It plays an immeasurable role. Although LED street lights have many advantages of energy saving and reducing environmental pollution, if they work under high current for a long time, they will generate a lot of heat. Excessive heat will easily cause the aging of LED emitters and cause LED lamps to burn. The light decay seriously affects the service life of street lights. In addition, the LED street lights on the market cannot provide different illuminance according to the environment. A few LED street lights with adjustable light simply use light sensors to compensate for light intensity. In the weather conditions with less fog and severe haze, it is impossible to intelligently distinguish whether someone is passing by, and the street lights are usually fully lit, resulting in a waste of energy
