Today, with the rapid development of artificial intelligence and intelligent manufacturing technologies, autonomous systems have moved from the laboratory to practical application scenarios. Self-driving cars, industrial AGVs (automated guided vehicles), drones, and household robots have gradually entered the public eye and become convenient and reliable tools in our daily lives and work. Autonomous systems, with their core capabilities of "perception - positioning - planning - decision-making - execution", are driving the replacement of social tools. Among these capabilities, laser ranging technology, with its unique technical advantages, becomes the core support for the perception layer and provides indispensable data support for the precise decision-making of autonomous systems. ERDI, as a professional provider of laser ranging technology solutions, systematically outlines the mechanism of laser ranging technology's role in autonomous systems and elaborates on its core value in autonomous systems.
I. Laser Ranging Technology: The "Perception Foundation" of Autonomous Systems
Laser ranging technology is a technology that emits laser signals and uses the propagation characteristics of light to calculate the distance between the emission point and the target object. It has advantages such as high precision and strong anti-interference ability. It is the cornerstone of autonomous perception systems. Compared with traditional visual sensing, microwave radar, and ultrasonic sensors, the main advantages of laser ranging technology are as follows:
1: Ultra-high-precision three-dimensional perception ability.
Visual sensing is affected by lighting and viewing angles; microwave radar can quickly obtain the distance and speed of the target, but has low resolution and cannot distinguish obstacles, while laser ranging technology can directly output three-dimensional point cloud data, accurately identify the target, distinguish objects, and provide clear and direct target environment information for autonomous systems.
2: Strong environmental adaptability and reliability.
Visual sensing is affected in complex weather conditions, and sometimes even loses its sensing ability; microwave radar has experienced signal degradation in dense obstacle scenes, affecting the sensing ability. However, laser ranging technology is not affected by lighting conditions, and the laser signal has strong anti-interference ability. Even in harsh weather or complex environments, it can still output data stably, ensuring the continuity and reliability of the perception layer of the autonomous system, which is the key to ensuring the safe operation of the autonomous system.
3: High data density.
When autonomous systems operate in dynamic environments, they need to obtain real-time information about environmental changes, such as when an autonomous vehicle is traveling at high speed, it needs to respond promptly to sudden situations such as the braking of the vehicle in front or pedestrians crossing the road. Some laser ranging technologies have a measurement frequency of over 5kHz, which can quickly capture environmental dynamic changes and meet the real-time data requirements of the autonomous system.
4: Good compatibility with multi-sensor fusion.
The data format of laser ranging technology is standardized and the features are clear, making it easy to fuse with GPS, IMU, cameras, etc. Sensors' data. Through multi-sensor fusion, it can make up for the shortcomings of a single sensor and improve the accuracy of the autonomous system's perception and positioning, providing a more reliable basis for subsequent planning and decision-making.
II. Applications of Laser Ranging in Various Autonomous Systems
1. Autonomous Vehicles Autonomous vehicles rely on high-precision sensors for real-time perception of the environment. Laser ranging technology is undoubtedly a key technology. Its main applications are as follows: - **Distance measurement and obstacle detection** Laser ranging devices can scan the vehicle's surroundings in real time and accurately detect pedestrians, vehicles, and obstacles on the road, reducing the probability of accidents. - **Environmental perception and 3D map construction** Through high-density point cloud data collection, the autonomous system can draw detailed 3D maps, achieve precise positioning and path planning, significantly improving driving safety and efficiency.
2. Drones and Robots The fields of drones and robots have high requirements for spatial perception capabilities. Laser ranging technology can assist with the following aspects - **Path planning and tracking** Laser ranging helps drones dynamically identify obstacles and achieve intelligent obstacle avoidance and autonomous flight, effectively enhancing operational capabilities. - **Spatial mapping and obstacle avoidance** Service robots or logistics robots rely on laser ranging to scan the indoor layout in real time, establish spatial maps, and intelligently adjust their movement trajectories based on environmental changes.
3. Industrial Automation Systems Industrial automation is undergoing an intelligent revolution. - **Intelligent warehousing handling, logistics robots** Laser ranging supports warehouse robots in precise positioning and path selection, significantly optimizing the efficiency of automatic handling and sorting. - **Automatic sorting and assembly** On automatic assembly lines, laser ranging can be used to detect the position and posture of parts, ensuring assembly accuracy and achieving precise operations.
4. Intelligent Security and Monitoring Laser ranging is also indispensable in the field of intelligent security: In modern border patrols and military ISR missions, harsh border environments and complex reflected light can easily interfere with security and monitoring. For this, laser ranging modules combined with thermal imaging, radar, and artificial intelligence form a 24/7 perception defense line, capable of judging target levels and improving the accuracy of security and monitoring.
