Lidar uses laser light to detect distance and image. Its main functions include: precise ranging and modeling, for terrain mapping, architectural scanning and archaeological survey. 3D imaging, generating point clouds for virtual reality, object recognition and architectural analysis. Self-driving cars provide three-dimensional environmental maps and sense obstacles and road conditions. Industrial automation for robot navigation, product inspection and automated warehousing. Remote sensing and atmospheric observations, detecting clouds, measuring vegetation height and measuring wind speed.
The role of lidar
Lidar (LiDAR) is a method that uses laser pulses for distance detection and imaging remote sensing technology. Its main functions include:
1. High-precision ranging and modeling
Lidar emits laser pulses, and by measuring the time difference between the pulses reflected back to the sensor, the target object can be accurately calculated distance and shape. This capability makes lidar ideal for the following applications:
2. Three-dimensional imaging
Lidar can generate highly detailed three-dimensional images (point clouds) by scanning target objects and recording the distance information of each point. These point clouds can be used to:
3. Self-driving cars
Lidar is one of the key sensors for self-driving cars. It provides a high-resolution three-dimensional map of the surrounding environment, allowing the car to accurately perceive obstacles, traffic and road conditions.
4. Industrial automation
Lidar is also widely used in industrial automation, such as:
5. Remote Sensing and Atmospheric Observation
Lidar is also used for remote sensing and atmospheric observation, such as:
