How does lidar explore a world invisible to the human eye? green laser pointer radar is an optical remote sensing technology that uses laser detection and ranging sensors to send laser pulses to draw detailed 3D maps. In recent years, lidar has become more and more hot, because this technology has promoted the development of autonomous vehicles, Self-driving cars can sense and navigate automatically, but this technology is not only used in the transportation industry. Lidar can help machines see and influence people’s perception of the physical world.
For example, installed on a helicopter flying over a valley, Lidar can shoot laser pulses through dense forests to help find these ancient sites. Using these data, researchers can discover unnatural archeological features, and thus traces of human activity. Classification and cartography dates back thousands of years to nature paintings, such as maps of ancient cities depicting the border between Babylon and Egyptian property. Over the past few thousand years, an increasing understanding of Earth, geography, and mathematics has produced increasingly complex maps.
From the first map of Greece in the 15th century to the launch of Google Earth in 2005, the mapping of maps has changed dramatically, and the green laser pointers radar may be the pioneer in pioneering the next generation of map technology. The use of lidar mapping is not a new concept. NASA used lidar to study the lunar surface during the Apollo mission in 1971 was one of the early applications, but this technology has become more advanced over time.
