Lidar has become an archaeological “artifact”. Outline map of the ancient underground city found by the radar green laser pointer. The United Kingdom maps the data collected by lidar into 3D images. With the development of science and technology, new technologies are gradually applied in various fields. Like early explorers who used maps to explore the unknown world, humans are now discovering lost civilizations and planning future cities in a more advanced way. Lidar, like the third eye of humans, has already played a huge role in map applications.
The ability of humans to explore the mysteries of the world is constantly increasing, and the pace is also accelerating. On the one hand, through various advanced technologies, we can continue to broaden our horizons and understand the vast space; on the other hand, we are constantly looking back at the past and understanding our own history. Lidar: This is a remote sensing technology that uses ultraviolet, visible, or near-infrared light to image an object. Lasers can penetrate dense forests and water bodies of a certain depth to obtain three-dimensional spatial data under the forest or in the water. Through the accumulation and superposition of point data, three-dimensional graphics with a certain degree of clarity can be formed.
Britain used green laser pointers to scan the country and found many historical sites. Lidar technology, which is used for autonomous driving, is also widely used to collect urban geographic information and discover historical sites. The original purpose of Britain’s land scan was to prevent floods. Since 1998, the UK Department of Environmental Protection has used laser radar to scan the British territory and draw the collected data into 3D images. The original purpose of the project was to record coastline changes and prevent floods, but now it has been used for a variety of new purposes such as urban planning and illegal dumping.
