[0002] Unmanned aerial vehicles (UAVs) are robotic systems capable of autonomous flight and are widely used in military, industrial, agricultural, and scientific research applications. The earliest UAVs originated in the early 20th century and were initially used primarily for military reconnaissance and targeting. With technological advancements, their applications have rapidly expanded. Modern UAVs are typically equipped with high-performance sensors, infrared cameras, and Global Positioning Systems (GPS), enabling them to perform a variety of missions. The rapid development of UAVs, fueled by advances in computer technology, wireless communications, and battery technology, has led to their increasing popularity in the military sector.

[0003] In the existing technology, although drones can realize ground infrared camera detection, they are unable to perform laser ranging processing on specific positions, so that they cannot perform distance measurement and dotting processing between the starting point and the point to be measured. At the same time, due to the one-way ranging of traditional laser rangefinders, when in use, a beam of rays is emitted to illuminate the target to achieve ranging, which limits its ranging range and can only achieve ranging processing of a single point position. It cannot better cooperate with infrared cameras to perform large-area scanning and ranging, which makes its ranging area. Therefore, there is an urgent need to provide a ranging and dotting drone to solve the above technical problems. Utility Model Content
