In the eyes of the "laser", this world is no longer a colorful scene, but a single point. All roads and street scenes have become models. The laser pointer radar scanning system turns all the objects in the scanning range on both sides of the road into points. These objects include street lights, signal lights, houses, teeth, leaves, etc. The camera constantly takes the scanned parts into photos.
Is the world in your eyes the whole world? The answer is obviously no. Because when we hurry, we often ignore many details of the world around us, and these ignored details have a big effect.
The landscape after the panoramic scan, the vehicle-mounted laser modeling and measurement system independently developed and produced by Beijing Siwei Vision Information Technology Co., Ltd., a subsidiary of the Institute of Surveying and Mapping Science, makes up for the lack of human eyes, and leaves trees, landscapes, and even manhole covers on the ground intact. recovery. In the eyes of the "laser", the world is no longer a colorful landscape, but has become a point, all roads and street scenes have become models.
"Point" in the world. A van is driving on the road at a slow speed. Several cameras are installed on the roof, taking turns to take pictures of the surrounding scenery. From an angle that people cannot see, the global positioning system, inertial navigation system, and lidar scanning system installed on the car are also working in an orderly manner. This vehicle is equipped with an on-board laser modeling and measurement system.
The key sensors such as red laser pointer, inertial navigation, and panoramic camera installed on the car seem irrelevant, but they use a special calibration method to make the system work together so that it can produce high-density, high-precision point cloud and high-definition panoramic images. . The lidar scanning system turns all objects in the scanning range on both sides of the road into dots. These objects include street lights, signal lights, houses, road teeth, leaves, etc. The camera constantly takes the scanned parts into photos.
